# Contributing
PhotonCloud uses Nix as the primary development and validation entrypoint.
## Setup
```bash
nix develop
```
## Before sending changes
Run the strongest local validation you can afford.
```bash
nix run ./nix/test-cluster#cluster -- fresh-smoke
```
For smaller changes, use the narrower commands under `nix/test-cluster`.
## Expectations
- keep service startup on file-first `--config` paths
- prefer Nix-native workflows over ad hoc host scripts
- do not commit secrets, private keys, runtime state, or generated disk images
- document new validation entrypoints in `README.md` or `docs/`
- when changing multi-node behavior, validate on the VM cluster rather than only with unit tests

# PlasmaCloud/PhotonCloud と Nix-NOS の統合分析
## Architecture Decision (2025-12-13)
**決定:** Nix-NOSを汎用ネットワークモジュールとして別リポジトリに分離する。
### Three-Layer Architecture
```
Layer 3: PlasmaCloud Cluster (T061)
- plasmacloud-cluster.nix
- cluster-config.json生成
- Deployer (Rust)
depends on ↓
Layer 2: PlasmaCloud Network (T061)
- plasmacloud-network.nix
- FiberLB BGP連携
- PrismNET統合
depends on ↓
Layer 1: Nix-NOS Generic (T062) ← 別リポジトリ
- BGP (BIRD2/GoBGP)
- VLAN
- Network interfaces
- PlasmaCloudを知らない汎用モジュール
```
### Repository Structure
- **github.com/centra/nix-nos**: Layer 1 (汎用、VyOS/OpenWrt代替)
- **github.com/centra/plasmacloud**: Layers 2+3 (既存リポジトリ)
---
## 1. 既存プロジェクトの概要
PlasmaCloud（PhotonCloud）は、以下のコンポーネントで構成されるクラウド基盤プロジェクト：
### コアサービス
| コンポーネント | 役割 | 技術スタック |
|---------------|------|-------------|
| **ChainFire** | 分散KVストア（etcd互換） | Rust, Raft (openraft) |
| **FlareDB** | SQLデータベース | Rust, KVバックエンド |
| **IAM** | 認証・認可 | Rust, JWT/mTLS |
| **PlasmaVMC** | VM管理 | Rust, KVM/FireCracker |
| **PrismNET** | オーバーレイネットワーク | Rust, OVN連携 |
| **LightningSTOR** | オブジェクトストレージ | Rust, S3互換 |
| **FlashDNS** | DNS | Rust, hickory-dns |
| **FiberLB** | ロードバランサー | Rust, L4/L7, BGP予定 |
| **NightLight** | メトリクス | Rust, Prometheus互換 |
| **k8shost** | コンテナオーケストレーション | Rust, K8s API互換 |
### インフラ層
- **NixOSモジュール**: 各サービス用 (`nix/modules/`)
- **first-boot-automation**: 自動クラスタ参加
- **PXE/Netboot**: ベアメタルプロビジョニング
- **TLS証明書管理**: 開発用証明書生成スクリプト
---
## 2. Nix-NOS との統合ポイント
### 2.1 Baremetal Provisioning → Deployer強化
**既存の実装:**
```
first-boot-automation.nix
├── cluster-config.json による設定注入
├── bootstrap vs join の自動判定
├── マーカーファイルによる冪等性
└── systemd サービス連携
```
**Nix-NOSで追加すべき機能:**
| 既存 | Nix-NOS追加 |
|------|-------------|
| cluster-config.json (手動作成) | topology.nix から自動生成 |
| 単一クラスタ構成 | 複数クラスタ/サイト対応 |
| nixos-anywhere 依存 | Deployer (Phone Home + Push) |
| 固定IP設定 | IPAM連携による動的割当 |
**統合設計:**
```nix
# topology.nix（Nix-NOS）
{
nix-nos.clusters.plasmacloud = {
nodes = {
"node01" = {
role = "control-plane";
ip = "10.0.1.10";
services = [ "chainfire" "flaredb" "iam" ];
};
"node02" = { role = "control-plane"; ip = "10.0.1.11"; };
"node03" = { role = "worker"; ip = "10.0.1.12"; };
};
# Nix-NOSが自動生成 → first-boot-automationが読む
# cluster-config.json の内容をNix評価時に決定
};
}
```
### 2.2 Network Management → PrismNET + FiberLB + Nix-NOS BGP
**既存の実装:**
```
PrismNET (prismnet/)
├── VPC/Subnet/Port管理
├── Security Groups
├── IPAM
└── OVN連携
FiberLB (fiberlb/)
├── L4/L7ロードバランシング
├── ヘルスチェック
├── VIP管理
└── BGP統合（設計済み、GoBGPサイドカー）
```
**Nix-NOSで追加すべき機能:**
```
Nix-NOS Network Layer
├── BGP設定生成（BIRD2）
│ ├── iBGP/eBGP自動計算
│ ├── Route Reflector対応
│ └── ポリシー抽象化
├── topology.nix → systemd-networkd
├── OpenWrt/Cisco設定生成（将来）
└── FiberLB BGP連携
```
**統合設計:**
```nix
# Nix-NOSのBGPモジュール → FiberLBのGoBGP設定に統合
{
nix-nos.network.bgp = {
autonomousSystems = {
"65000" = {
members = [ "node01" "node02" "node03" ];
ibgp.strategy = "route-reflector";
ibgp.reflectors = [ "node01" ];
};
};
# FiberLBのVIPをBGPで広報
vipAdvertisements = {
"fiberlb" = {
vips = [ "10.0.100.1" "10.0.100.2" ];
nextHop = "self";
communities = [ "65000:100" ];
};
};
};
# FiberLBモジュールとの連携
services.fiberlb.bgp = {
enable = true;
# Nix-NOSが生成するGoBGP設定を参照
configFile = config.nix-nos.network.bgp.gobgpConfig;
};
}
```
### 2.3 K8sパチモン → k8shost + Pure NixOS Alternative
**既存の実装:**
```
k8shost (k8shost/)
├── Pod管理（gRPC API）
├── Service管理（ClusterIP/NodePort）
├── Node管理
├── CNI連携
├── CSI連携
└── FiberLB/FlashDNS連携
```
**Nix-NOSの役割:**
k8shostはすでにKubernetesのパチモンとして機能している。Nix-NOSは：
1. **k8shostを使う場合**: k8shostクラスタ自体のデプロイをNix-NOSで管理
2. **Pure NixOS（K8sなし）**: より軽量な選択肢として、Systemd + Nix-NOSでサービス管理
```
┌─────────────────────────────────────────────────────────────┐
│ Orchestration Options │
├─────────────────────────────────────────────────────────────┤
│ Option A: k8shost (K8s-like) │
│ ┌─────────────────────────────────────────────────────┐ │
│ │ Nix-NOS manages: cluster topology, network, certs │ │
│ │ k8shost manages: pods, services, scaling │ │
│ └─────────────────────────────────────────────────────┘ │
│ │
│ Option B: Pure NixOS (K8s-free) │
│ ┌─────────────────────────────────────────────────────┐ │
│ │ Nix-NOS manages: everything │ │
│ │ systemd + containers, static service discovery │ │
│ │ Use case: クラウド基盤自体の管理 │ │
│ └─────────────────────────────────────────────────────┘ │
└─────────────────────────────────────────────────────────────┘
```
**重要な洞察:**
> 「クラウドの基盤そのものを作るのにKubernetesは使いたくない」
これは正しいアプローチ。PlasmaCloudのコアサービス（ChainFire, FlareDB, IAM等）は：
- K8sの上で動くのではなく、K8sを提供する側
- Pure NixOS + Systemdで管理されるべき
- Nix-NOSはこのレイヤーを担当
---
## 3. 具体的な統合計画
### Phase 1: Baremetal Provisioning統合
**目標:** first-boot-automationをNix-NOSのtopology.nixと連携
```nix
# nix/modules/first-boot-automation.nix への追加
{ config, lib, ... }:
let
# Nix-NOSのトポロジーから設定を生成
clusterConfig =
if config.nix-nos.cluster != null then
config.nix-nos.cluster.generateClusterConfig {
hostname = config.networking.hostName;
}
else
# 従来のcluster-config.json読み込み
builtins.fromJSON (builtins.readFile /etc/nixos/secrets/cluster-config.json);
in {
# 既存のfirst-boot-automationロジックはそのまま
# ただし設定ソースをNix-NOSに切り替え可能に
}
```
### Phase 2: BGP/Network統合
**目標:** FiberLBのBGP連携（T055.S3）をNix-NOSで宣言的に管理
```nix
# nix/modules/fiberlb-bgp-nixnos.nix
{ config, lib, pkgs, ... }:
let
fiberlbCfg = config.services.fiberlb;
nixnosBgp = config.nix-nos.network.bgp;
in {
config = lib.mkIf (fiberlbCfg.enable && nixnosBgp.enable) {
# GoBGP設定をNix-NOSから生成
services.gobgpd = {
enable = true;
configFile = pkgs.writeText "gobgp.yaml" (
nixnosBgp.generateGobgpConfig {
localAs = nixnosBgp.getLocalAs config.networking.hostName;
routerId = nixnosBgp.getRouterId config.networking.hostName;
neighbors = nixnosBgp.getPeers config.networking.hostName;
}
);
};
# FiberLBにGoBGPアドレスを注入
services.fiberlb.bgp = {
gobgpAddress = "127.0.0.1:50051";
};
};
}
```
### Phase 3: Deployer実装
**目標:** Phone Home + Push型デプロイメントコントローラー

**ChainFireとの連携:**
DeployerはChainFireを状態ストアとして使用：
```rust
// deployer/src/state.rs
struct NodeState {
hostname: String,
status: NodeStatus, // Pending, Provisioning, Active, Failed
bootstrap_key_hash: Option<String>,
ssh_pubkey: Option<String>,
last_seen: DateTime<Utc>,
}
impl DeployerState {
async fn register_node(&self, node: &NodeState) -> Result<()> {
// ChainFireに保存
self.chainfire_client
.put(format!("deployer/nodes/{}", node.hostname), node.to_json())
.await
}
}
```

## 6. 結論
PlasmaCloud/PhotonCloudプロジェクトは、Nix-NOSの構想を実装するための**理想的な基盤**：
1. **すでにNixOSモジュール化されている** → Nix-NOSモジュールとの統合が容易
2. **first-boot-automationが存在** → Deployerの基礎として活用可能
3. **FiberLBにBGP設計がある** → Nix-NOSのBGPモジュールと自然に統合
4. **ChainFireが状態ストア** → Deployer状態管理に利用可能
5. **k8shostが存在するがK8sではない** → 「K8sパチモン」の哲学と一致
**次のアクション:**
1. Nix-NOSモジュールをPlasmaCloudリポジトリに追加
2. topology.nix → cluster-config.json生成の実装
3. BGPモジュール（BIRD2）の実装とFiberLB連携

# Project Overview
これは、日本発のクラウド基盤を作るためのプロジェクトです。
OpenStackなどの既存の使いにくいクラウド基板の代替となり、ついでに基礎技術を各種ソフトウェアに転用できるようにする。
# Principal
Peer Aへ：**自分で戦略を**決めて良い！好きにやれ！
# Current Priorities
一通り実装を終わらせ、使いやすいプラットフォームと仕様が完成することを目標とする。
実装すべきもの：
1. クラスター管理用KVS（chainfire）
- これは、ライブラリとして作ることにする。単体でとりあえずKVSとして簡易的にも使えるという想定。
- Raft+Gossip。
2. IAM基盤（aegisという名前にしたい。）
- 様々な認証方法に対応しておいてほしい。
- あと、サービス感の認証もうまくやる必要がある。mTLSでやることになるだろう。IAMとしてやるのが正解かどうかはわからないが。
3. DBaaSのための高速KVS（FlareDB）
- そこそこクエリ効率の良いKVSを作り、その上にSQL互換レイヤーなどが乗れるようにする。
- 超高速である必要がある。
- 結果整合性モードと強整合性モードを両方載せられるようにしたい。
- Tsurugiのような高速なDBが参考になるかも知れない。
- DBaaSのためでもあるが、高速分散KVSということで、他のもののメタデータストアとして使えるべき。
- Chainfireとの棲み分けとしては、Chainfireは単体で使う時用と、大規模な場合はクラスター管理に集中させ、メタデータのストア（特に、サービ ス感の連携をするような場合は他のサービスのメタデータにアクセスしたくなるだろう。その時に、このKVSから読めれば良い。）はFlareDBにすると良 さそう。
4. VM基盤（PlasmaVMC）
- ちゃんとした抽象化をすることで、様々なVMを扱えるようにしたい（KVM,FireCracker,mvisorなどなど）
5. オブジェクトストレージ基盤（LightningSTOR）
- この基盤の標準的な感じの（ある程度共通化されており、使いやすい）APIと、S3互換なAPIがあると良いかも
- メタデータストアにFlareDBが使えるように当然なっているべき
6. DNS（FlashDNS）
- PowerDNSを100%完全に代替可能なようにしてほしい。
- Route53のようなサービスが作れるようにしたい。
- BINDも使いたくない。
- 逆引きDNSをやるためにとんでもない行数のBINDのファイルを書くというのがあり、バカバカしすぎるのでサブネットマスクみたいなものに対応すると良い。
- DNS All-Rounderという感じにしたい。
7. ロードバランサー（FiberLB）
- 超高速なロードバランサーとは名ばかりで、実体としてはBGPでやるので良いような気がしている。
- AWS ELBみたいなことをできるようにしたい。
- MaglevによるL4ロードバランシング
- BGP AnycastによるL2ロードバランシング
- L7ロードバランシング
- これらをいい感じにできると良い（既存のソフトウェアでできるかも？これは要確認。）
8. Kubernetesクラスタをいい感じにホストできるもの？
- k0sとかk3sとかが参考になるかも知れない。
9. これらをNixOS上で動くようにパッケージ化をしたりすると良い（Flake化？）。
- あと、Nixで設定できると良い。まあ設定ファイルを生成するだけなのでそれはできると思うが
10. Nixによるベアメタルプロビジョニング（Deployer）
- Phone Home + Push型のデプロイメントコントローラー
- topology.nix からクラスタ設定を自動生成
- ChainFireを状態ストアとして使用
- ISO自動生成パイプライン対応
11. オーバーレイネットワーク
- マルチテナントでもうまく動くためには、ユーザーの中でアクセスできるネットワークなど、考えなければいけないことが山ほどある。これを処理 するものも必要。
- とりあえずネットワーク部分自体の実装はOVNとかで良い。
12. オブザーバビリティコンポーネント（NightLight）
- メトリクスストアが必要
- VictoriaMetricsはmTLSが有料なので、作る必要がある
- 完全オープンソースでやりたいからね
- 最低限、Prometheus互換（PromQL）とスケーラビリティ、Push型というのは必須になる
- メトリクスのデータをどこに置くかは良く良く考えないといけない。スケーラビリティを考えるとS3互換ストレージの上に載せたいが…？
- あと、圧縮するかどうかなど
13. クレジット・クオータ管理（CreditService）
- プロジェクトごとのリソース使用量と課金を管理する「銀行」のようなサービス
- 各サービス（PlasmaVMCなど）からのリソース作成リクエストをインターセプトして残高確認（Admission Control）を行う
- NightLightから使用量メトリクスを収集して定期的に残高を引き落とす（Billing Batch）
# Recent Changes (2025-12-11)
- **Renaming**:
- `Nightlight` -> `NightLight` (監視・メトリクス)
- `PrismNET` -> `PrismNET` (ネットワーク)
- `PlasmaCloud` -> `PhotonCloud` (プロジェクト全体コードネーム)
- **Architecture Decision**:
- IAMにクオータ管理を持たせず、専用の `CreditService` を新設することを決定。
- `NightLight` を使用量計測のバックエンドとして活用する方針を策定。
# Next Steps
1. **CreditServiceの実装**:
- プロジェクトごとのWallet管理、残高管理機能
- gRPC APIによるAdmission Controlの実装
2. **NightLightの実装完了**:
- 永続化層とクエリエンジンの完成
- `CreditService` へのデータ提供機能の実装
3. **PlasmaVMCの改修**:
- `CreditService` と連携したリソース作成時のチェック処理追加
- プロジェクト単位のリソース総量制限の実装
# 守るべき事柄
1. Rustで書く。
2. 全部のソフトウェアにおいて、コードベースの構造や依存ライブラリ、仕様や使い方を揃えて、統一感があるようにする。
3. テスト可能なように作る。また、テストをちゃんと書く。スケーラブルかどうかや、実際に動くかどうかもテスト可能なように良く考えたうえで作る。
4. スケーラビリティに気をつけて書く。ボトルネックになる箇所はないか？と常に確認する。
5. 統一感ある仕様をちゃんと考える。（specificationsの中にmdで書いていってほしい。1ソフトウェアごとにフォルダを作り、その中に仕様を書く。 ）
6. 設定ファイルについても統一感ある仕様が必要。
7. マルチテナントに関して最初から考慮したうえで設計する（次の年にAWSやGCPでそのまま採用されてもおかしくないような性能や使いやすさが必要）。
8. ホームラボ用途も満たすようにしたい。
9. NixのFlakeで環境を作ったり固定したりすると良い。
10. 前方互換性は気にする必要がない（すでにある実装に縛られる必要はなく、両方を変更して良い）。v2とかv3とかそういうふうにバージョンを増やしていくのはやめてほしい。そうではなく、完璧な一つの実装を作ることに専念してほしい。
11. ライブラリは可能な限り最新版を使う。この先も長くメンテナンスされることを想定したい。
# 実戦テスト
全ての作ったコンポーネントについて、実践的なテストを作ってバグや仕様の悪い点を洗い出し、修正する。
NixやVM、コンテナなどあらゆるものを活用してよい。
これにより、実用レベルまで持っていくことが期待される。
実用的なアプリケーションを作ってみるとか、パフォーマンスを実際に高負荷な試験で確認するとか、そのレベルのものが求められている。
また、各コンポーネントごとのテストも行うべきだが、様々なものを組み合わせるテストも行うべきである。これも含まれる。
また、設定のやり方がちゃんと統一されているかなど、細かい点まで気を配ってやる必要がある。

# PhotonCloud
# PhotonCloud (旧 PlasmaCloud)
PhotonCloud is a Nix-first cloud platform workspace that assembles a small control plane, network services, VM hosting, shared storage, object storage, and gateway services into one reproducible repository.
**A modern, multi-tenant cloud infrastructure platform built in Rust**
The canonical local proof path is the six-node VM cluster under [`nix/test-cluster`](/home/centra/cloud/nix/test-cluster/README.md). It builds all guest images on the host, boots them as hardware-like QEMU nodes, and validates real multi-node behavior.
> NOTE: プロジェクトコードネームを PlasmaCloud から PhotonCloud に改称。コンポーネント名も Nightlight → NightLight へ統一済み（詳細は `PROJECT.md` の Recent Changes を参照）。
> 併存する「PlasmaCloud」表記は旧コードネームを指します。PhotonCloud と読み替えてください。
## Components
PhotonCloud provides a complete cloud computing stack with strong tenant isolation, role-based access control (RBAC), and seamless integration between compute, networking, and storage services.
- `chainfire`: replicated coordination store
- `flaredb`: replicated KV and metadata store
- `iam`: identity, token issuance, and authorization
- `prismnet`: tenant networking control plane
- `flashdns`: authoritative DNS service
- `fiberlb`: load balancer control plane and dataplane
- `plasmavmc`: VM control plane and worker agents
- `coronafs`: shared filesystem for mutable VM volumes
- `lightningstor`: object storage and VM image backing
- `k8shost`: Kubernetes-style hosting control plane
- `apigateway`: external API and proxy surface
- `nightlight`: metrics ingestion and query service
- `creditservice`: minimal reference quota/credit service
- `deployer`: bootstrap and phone-home deployment service
- `fleet-scheduler`: non-Kubernetes service scheduler for bare-metal cluster services

## Tenant Isolation Model
PlasmaCloud enforces tenant isolation at three layers:
### Layer 1: IAM Policy Enforcement
Every API call is validated against the user's JWT token:
- Token includes `org_id` and `project_id` claims
- Resources are scoped as: `org/{org_id}/project/{project_id}/{resource_type}/{id}`
- RBAC policies enforce: `resource.org_id == token.org_id`
- Cross-tenant access results in 403 Forbidden
### Layer 2: Network VPC Isolation
Each VPC provides a logical network boundary:
- VPC scoped to an `org_id`
- OVN overlay ensures traffic isolation between VPCs
- Different tenants can use the same CIDR without collision
- Security groups provide intra-VPC firewall rules
### Layer 3: VM Scoping
Virtual machines are scoped to tenant organizations:
- VM metadata includes `org_id` and `project_id`
- VMs can only attach to ports in their tenant's VPC
- VM operations filter by token scope
- Hypervisor isolation ensures compute boundary
**Validation**: All three layers tested in [cross-tenant denial tests](docs/por/T023-e2e-tenant-path/e2e_test.md#test-scenario-2-cross-tenant-denial).
## Example Workflow
### Create a Tenant with Network and VM
```bash
# 1. Authenticate and get token
grpcurl -plaintext -d '{
"principal_id": "alice",
"org_id": "acme-corp",
"project_id": "project-alpha"
}' localhost:50080 iam.v1.IamTokenService/IssueToken
export TOKEN="<your-token>"
# 2. Create VPC
grpcurl -plaintext -H "Authorization: Bearer $TOKEN" -d '{
"org_id": "acme-corp",
"project_id": "project-alpha",
"name": "main-vpc",
"cidr": "10.0.0.0/16"
}' localhost:50081 prismnet.v1.VpcService/CreateVpc
export VPC_ID="<vpc-id>"
# 3. Create Subnet
grpcurl -plaintext -H "Authorization: Bearer $TOKEN" -d '{
"org_id": "acme-corp",
"project_id": "project-alpha",
"vpc_id": "'$VPC_ID'",
"name": "web-subnet",
"cidr": "10.0.1.0/24",
"gateway": "10.0.1.1",
"dhcp_enabled": true
}' localhost:50081 prismnet.v1.SubnetService/CreateSubnet
export SUBNET_ID="<subnet-id>"
# 4. Create Port
grpcurl -plaintext -H "Authorization: Bearer $TOKEN" -d '{
"org_id": "acme-corp",
"project_id": "project-alpha",
"subnet_id": "'$SUBNET_ID'",
"name": "vm-port",
"ip_address": "10.0.1.10"
}' localhost:50081 prismnet.v1.PortService/CreatePort
export PORT_ID="<port-id>"
# 5. Create VM with Network
grpcurl -plaintext -H "Authorization: Bearer $TOKEN" -d '{
"name": "web-server-1",
"org_id": "acme-corp",
"project_id": "project-alpha",
"spec": {
"network": [{
"id": "eth0",
"port_id": "'$PORT_ID'"
}]
}
}' localhost:50082 plasmavmc.v1.VmService/CreateVm
```

# Architectural Gap Analysis: Compute & Core
**Date:** 2025-12-08
**Scope:** Core Infrastructure (Chainfire, IAM, FlareDB) & Application Services (FlashDNS, PlasmaVMC)
## Executive Summary
The platform's core infrastructure ("Data" and "Identity" pillars) is in excellent shape, with implementation matching specifications closely. However, the "Compute" pillar (PlasmaVMC) exhibits a significant architectural deviation from its specification, currently existing as a monolithic prototype rather than the specified distributed control plane/agent model.
## Component Status Matrix
| Component | Role | Specification Status | Implementation Status | Alignment |
|-----------|------|----------------------|-----------------------|-----------|
| **Chainfire** | Cluster KVS | High | High | ✅ Strong |
| **Aegis (IAM)** | Identity | High | High | ✅ Strong |
| **FlareDB** | DBaaS KVS | High | High | ✅ Strong |
| **FlashDNS** | DNS Service | High | High | ✅ Strong |
| **PlasmaVMC** | VM Platform | High | **Low / Prototype** | ❌ **Mismatch** |
## Detailed Findings
### 1. Core Infrastructure (Chainfire, Aegis, FlareDB)
* **Chainfire:** Fully implemented crate structure. Detailed feature gap analysis exists (`chainfire_t003_gap_analysis.md`).
* **Aegis:** Correctly structured with `iam-server`, `iam-authn`, `iam-authz`, etc. Integration with Chainfire/FlareDB backends is present in `main.rs`.
* **FlareDB:** Correctly structured with `flaredb-pd`, `flaredb-server` (Multi-Raft), and reserved namespaces for IAM/Metrics.
### 2. Application Services (FlashDNS)
* **Status:** Excellent.
* **Evidence:** Crate structure matches spec. Integration with Chainfire (storage) and Aegis (auth) is visible in configuration and code.
### 3. Compute Platform (PlasmaVMC) - The Gap
* **Specification:** Describes a distributed system with:
* **Control Plane:** API, Scheduler, Image management.
* **Agent:** Runs on compute nodes, manages local hypervisors.
* **Communication:** gRPC between Control Plane and Agent.
* **Current Implementation:** Monolithic `plasmavmc-server`.
* The `server` binary directly initializes `HypervisorRegistry` and registers `KvmBackend`/`FireCrackerBackend`.
* **Missing Crates:**
* `plasmavmc-agent` (Critical)
* `plasmavmc-client`
* `plasmavmc-core` (Scheduler logic)
* **Implication:** The current code cannot support multi-node deployment or scheduling. It effectively runs the control plane *on* the hypervisor node.
## Recommendations
1. **Prioritize PlasmaVMC Refactoring:** The immediate engineering focus should be to split `plasmavmc-server` into:
* `plasmavmc-server` (Control Plane, Scheduler, API)
* `plasmavmc-agent` (Node status, Hypervisor control)
2. **Implement Agent Protocol:** Define the gRPC interface between Server and Agent (`agent.proto` mentioned in spec but possibly missing or unused).
3. **Leverage Existing Foundation:** The `plasmavmc-hypervisor` trait is solid. The `agent` implementation should simply wrap this existing trait, making the refactor straightforward.
## Conclusion
The project foundation is solid. The "Data" and "Identity" layers are ready for higher-level integration. The "Compute" layer requires architectural realignment to meet the distributed design goals.

# First-Boot Automation Architecture
## Overview
The first-boot automation system provides automated cluster joining and service initialization for bare-metal provisioned nodes. It handles two critical scenarios:
1. **Bootstrap Mode**: First 3 nodes initialize a new Raft cluster
2. **Join Mode**: Additional nodes join an existing cluster
This document describes the architecture, design decisions, and implementation details.

```
### Bootstrap Mode (bootstrap: true)
**When to use:**
- First 3 nodes in a new cluster
- Nodes configured with matching `initial_peers`
- No existing cluster to join
**Behavior:**
1. Service starts with `--initial-cluster` parameter containing all bootstrap peers
2. Raft consensus protocol automatically elects leader
3. Cluster join service detects bootstrap mode and exits immediately
4. No API calls to leader (cluster doesn't exist yet)
**Configuration:**
```json
{
"bootstrap": true,
"initial_peers": ["node01:2380", "node02:2380", "node03:2380"]
}
```
**Marker file:** `/var/lib/first-boot-automation/.chainfire-initialized`
### Join Mode (bootstrap: false)
**When to use:**
- Nodes joining an existing cluster
- Expansion or replacement nodes
- Leader URL is known and reachable
**Behavior:**
1. Service starts with no initial cluster configuration
2. Cluster join service waits for local service health
3. POST to leader's `/admin/member/add` with node info
4. Leader adds member to Raft configuration
5. Node joins cluster and synchronizes state
**Configuration:**
```json
{
"bootstrap": false,
"leader_url": "https://node01.example.com:2379",
"raft_addr": "10.0.1.13:2380"
}
```
**Marker file:** `/var/lib/first-boot-automation/.chainfire-joined`
## Idempotency and State Management
### Marker Files
The system uses marker files to track initialization state:
```
/var/lib/first-boot-automation/
├── .chainfire-initialized # Bootstrap node initialized
├── .chainfire-joined # Node joined cluster
├── .flaredb-initialized # FlareDB bootstrap
├── .flaredb-joined # FlareDB joined
└── .iam-initialized # IAM setup complete
```
**Purpose:**
- Prevent duplicate join attempts on reboot
- Support idempotent operations
- Enable troubleshooting (check timestamps)
**Format:** ISO8601 timestamp of initialization
```
2025-12-10T10:30:45+00:00
```
### State Transitions
```

│ First Boot │
│ (no marker) │
└──────┬───────┘
│
▼
┌──────────────┐
│ Check Config │
│ bootstrap=? │
└──────┬───────┘
│
├─(true)──▶ Bootstrap ──▶ Create .initialized ──▶ Done
│
└─(false)─▶ Join ──▶ Create .joined ──▶ Done
│
│ (reboot)
▼
┌──────────────┐
│ Marker Exists│
│ Skip Join │
└──────────────┘
```
## Retry Logic and Error Handling
### Health Check Retry
**Parameters:**
- Timeout: 120 seconds (configurable)
- Retry Interval: 5 seconds
- Max Elapsed: 300 seconds
**Logic:**
```bash
START_TIME=$(date +%s)
while true; do
ELAPSED=$(($(date +%s) - START_TIME))
if [[ $ELAPSED -ge $TIMEOUT ]]; then
exit 1 # Timeout
fi
HTTP_CODE=$(curl -k -s -o /dev/null -w "%{http_code}" "$HEALTH_URL")
if [[ "$HTTP_CODE" == "200" ]]; then
exit 0 # Success
fi
sleep 5
done
```
### Cluster Join Retry
**Parameters:**
- Max Attempts: 5 (configurable)
- Retry Delay: 10 seconds
- Exponential Backoff: Optional (not implemented)
**Logic:**
```bash
for ATTEMPT in $(seq 1 $MAX_ATTEMPTS); do
HTTP_CODE=$(curl -X POST "$LEADER_URL/admin/member/add" -d "$PAYLOAD")
if [[ "$HTTP_CODE" == "200" || "$HTTP_CODE" == "201" ]]; then
exit 0 # Success
elif [[ "$HTTP_CODE" == "409" ]]; then
exit 2 # Already member
fi
sleep $RETRY_DELAY
done
exit 1 # Max attempts exhausted
```
### Error Codes
**Health Check:**
- `0`: Service healthy
- `1`: Timeout or unhealthy
**Cluster Join:**
- `0`: Successfully joined
- `1`: Failed after max attempts
- `2`: Already joined (idempotent)
- `3`: Invalid arguments
**Bootstrap Detector:**
- `0`: Should bootstrap
- `1`: Should join existing
- `2`: Configuration error
## Security Considerations
### TLS Certificate Handling
**Requirements:**
- All inter-node communication uses TLS
- Self-signed certificates supported via `-k` flag to curl
- Certificate validation in production (remove `-k`)
**Certificate Paths:**
```json
{
"tls": {
"enabled": true,
"ca_cert_path": "/etc/nixos/secrets/ca.crt",
"node_cert_path": "/etc/nixos/secrets/node01.crt",
"node_key_path": "/etc/nixos/secrets/node01.key"
}
}
```
**Integration with T031:**
- Certificates generated by T031 TLS automation
- Copied to target during provisioning
- Read by services at startup
### Secrets Management
**Cluster Configuration:**
- Stored in `/etc/nixos/secrets/cluster-config.json`
- Permissions: `0600 root:root` (recommended)
- Contains sensitive data: URLs, IPs, topology
**API Credentials:**
- IAM admin credentials (future implementation)
- Stored in separate file: `/etc/nixos/secrets/iam-admin.json`
- Never logged to journald
### Attack Surface
**Mitigations:**
1. **Network-level**: Firewall rules restrict cluster API ports
2. **Application-level**: mTLS for authenticated requests
3. **Access control**: SystemD service isolation
4. **Audit**: All operations logged to journald with structured JSON
## Integration Points
### T024 NixOS Modules
The first-boot automation module imports and extends service modules:
```nix
# Example: netboot-control-plane.nix
{
imports = [
../modules/chainfire.nix
../modules/flaredb.nix
../modules/iam.nix
../modules/first-boot-automation.nix
];
services.first-boot-automation.enable = true;
}
```
### T031 TLS Certificates
**Dependencies:**
- TLS certificates must exist before first boot
- Provisioning script copies certificates to `/etc/nixos/secrets/`
- Services read certificates at startup
**Certificate Generation:**
```bash
# On provisioning server (T031)
./tls/generate-node-cert.sh node01.example.com 10.0.1.10
# Copied to target
scp ca.crt node01.crt node01.key root@10.0.1.10:/etc/nixos/secrets/
```
### T032.S1-S3 PXE/Netboot
**Boot Flow:**
1. PXE boot loads iPXE firmware
2. iPXE chainloads NixOS kernel/initrd
3. NixOS installer runs (nixos-anywhere)
4. System installed to disk with first-boot automation
5. Reboot into installed system
6. First-boot automation executes
**Configuration Injection:**
```bash
# During nixos-anywhere provisioning
mkdir -p /mnt/etc/nixos/secrets
cp cluster-config.json /mnt/etc/nixos/secrets/
chmod 600 /mnt/etc/nixos/secrets/cluster-config.json
```
## Service Dependencies
### Systemd Ordering
**Chainfire:**
```
After: network-online.target, chainfire.service
Before: flaredb-cluster-join.service
Wants: network-online.target
```
**FlareDB:**
```
After: chainfire-cluster-join.service, flaredb.service
Requires: chainfire-cluster-join.service
Before: iam-initial-setup.service
```
**IAM:**
```
After: flaredb-cluster-join.service, iam.service
Before: cluster-health-check.service
```
**Health Check:**
```
After: chainfire-cluster-join, flaredb-cluster-join, iam-initial-setup
Type: oneshot (no RemainAfterExit)
```
### Dependency Graph
```

## Logging and Observability
### Structured Logging
All scripts output JSON-formatted logs:
```json
{
"timestamp": "2025-12-10T10:30:45+00:00",
"level": "INFO",
"service": "chainfire",
"operation": "cluster-join",
"message": "Successfully joined cluster"
}
```
**Benefits:**
- Machine-readable for log aggregation (T025)
- Easy filtering with `journalctl -o json`
- Includes context (service, operation, timestamp)
### Querying Logs
**View all first-boot automation logs:**
```bash
journalctl -u chainfire-cluster-join.service -u flaredb-cluster-join.service \
-u iam-initial-setup.service -u cluster-health-check.service
```
**Filter by log level:**
```bash
journalctl -u chainfire-cluster-join.service | grep '"level":"ERROR"'
```
**Follow live:**
```bash
journalctl -u chainfire-cluster-join.service -f
```
### Health Check Integration
**T025 Observability:**
- Health check service can POST to metrics endpoint
- Prometheus scraping of `/health` endpoints
- Alerts on cluster join failures
**Future:**
- Webhook to provisioning server on completion
- Slack/email notifications on errors
- Dashboard showing cluster join status
## Performance Characteristics
### Boot Time Analysis
**Typical Timeline (3-node cluster):**
```
T+0s : systemd starts
T+5s : network-online.target reached
T+10s : chainfire.service starts
T+15s : chainfire healthy
T+15s : chainfire-cluster-join runs (bootstrap, immediate exit)
T+20s : flaredb.service starts
T+25s : flaredb healthy
T+25s : flaredb-cluster-join runs (bootstrap, immediate exit)
T+30s : iam.service starts
T+35s : iam healthy
T+35s : iam-initial-setup runs
T+40s : cluster-health-check runs
T+40s : Node fully operational
```
**Join Mode (node joining existing cluster):**
```
T+0s : systemd starts
T+5s : network-online.target reached
T+10s : chainfire.service starts
T+15s : chainfire healthy
T+15s : chainfire-cluster-join runs
T+20s : POST to leader, wait for response
T+25s : Successfully joined chainfire cluster
T+25s : flaredb.service starts
T+30s : flaredb healthy
T+30s : flaredb-cluster-join runs
T+35s : Successfully joined flaredb cluster
T+40s : iam-initial-setup (skips, already initialized)
T+45s : cluster-health-check runs
T+45s : Node fully operational
```
### Bottlenecks
**Health Check Polling:**
- 5-second intervals may be too aggressive
- Recommendation: Exponential backoff
**Network Latency:**
- Join requests block on network RTT
- Mitigation: Ensure low-latency cluster network
**Raft Synchronization:**
- New member must catch up on Raft log
- Time depends on log size (seconds to minutes)
## Failure Modes and Recovery
### Common Failures
**1. Leader Unreachable**
**Symptom:**
```json
{"level":"ERROR","message":"Join request failed: connection error"}
```
**Diagnosis:**
- Check network connectivity: `ping node01.example.com`
- Verify firewall rules: `iptables -L`
- Check leader service status: `systemctl status chainfire.service`
**Recovery:**
```bash
# Fix network/firewall, then restart join service
systemctl restart chainfire-cluster-join.service
```
**2. Invalid Configuration**
**Symptom:**
```json
{"level":"ERROR","message":"Configuration file not found"}
```
**Diagnosis:**
- Verify file exists: `ls -la /etc/nixos/secrets/cluster-config.json`
- Check JSON syntax: `jq . /etc/nixos/secrets/cluster-config.json`
**Recovery:**
```bash
# Fix configuration, then restart
systemctl restart chainfire-cluster-join.service
```
**3. Service Not Healthy**
**Symptom:**
```json
{"level":"ERROR","message":"Health check timeout"}
```
**Diagnosis:**
- Check service logs: `journalctl -u chainfire.service`
- Verify service is running: `systemctl status chainfire.service`
- Test health endpoint: `curl -k https://localhost:2379/health`
**Recovery:**
```bash
# Restart the main service
systemctl restart chainfire.service
# Join service will auto-retry after RestartSec
```
**4. Already Member**
**Symptom:**
```json
{"level":"WARN","message":"Node already member of cluster (HTTP 409)"}
```
**Diagnosis:**
- This is normal on reboots
- Marker file created to prevent future attempts
**Recovery:**
- No action needed (idempotent behavior)
### Manual Cluster Join
If automation fails, manual join:
**Chainfire:**
```bash
curl -k -X POST https://node01.example.com:2379/admin/member/add \
-H "Content-Type: application/json" \
-d '{"id":"node04","raft_addr":"10.0.1.13:2380"}'
# Create marker to prevent auto-retry
mkdir -p /var/lib/first-boot-automation
date -Iseconds > /var/lib/first-boot-automation/.chainfire-joined
```
**FlareDB:**
```bash
curl -k -X POST https://node01.example.com:2479/admin/member/add \
-H "Content-Type: application/json" \
-d '{"id":"node04","raft_addr":"10.0.1.13:2480"}'
date -Iseconds > /var/lib/first-boot-automation/.flaredb-joined
```
### Rollback Procedure
**Remove from cluster:**
```bash
# On leader
curl -k -X DELETE https://node01.example.com:2379/admin/member/node04
# On node being removed
systemctl stop chainfire.service
rm -rf /var/lib/chainfire/*
rm /var/lib/first-boot-automation/.chainfire-joined
# Re-enable automation
systemctl restart chainfire-cluster-join.service
```
## Future Enhancements
### Planned Improvements
**1. Exponential Backoff**
- Current: Fixed 10-second delay
- Future: 1s, 2s, 4s, 8s, 16s exponential backoff
**2. Leader Discovery**
- Current: Static leader URL in config
- Future: DNS SRV records for dynamic discovery
**3. Webhook Notifications**
- POST to provisioning server on completion
- Include node info, join time, cluster health
**4. Pre-flight Checks**
- Validate network connectivity before attempting join
- Check TLS certificate validity
- Verify disk space, memory, CPU requirements
**5. Automated Testing**
- Integration tests with real cluster
- Simulate failures (network partitions, leader crashes)
- Validate idempotency
**6. Configuration Validation**
- JSON schema validation at boot
- Fail fast on invalid configuration
- Provide clear error messages

## Overview
The first-boot automation system handles automated cluster joining for distributed services (Chainfire, FlareDB, IAM) on first boot of bare-metal provisioned nodes. It supports two modes:
- **Bootstrap Mode**: Initialize a new Raft cluster (first 3 nodes)
- **Join Mode**: Join an existing cluster (additional nodes)
### Features
- Automated health checking with retries
- Idempotent operations (safe to run multiple times)
- Structured JSON logging to journald
- Graceful failure handling with configurable retries
- Integration with TLS certificates (T031)
- Support for both bootstrap and runtime join scenarios
### Architecture
See [ARCHITECTURE.md](ARCHITECTURE.md) for detailed design documentation.
## Quick Start
### Prerequisites
1. Node provisioned via T032.S1-S3 (PXE boot and installation)
2. Cluster configuration file at `/etc/nixos/secrets/cluster-config.json`
3. TLS certificates at `/etc/nixos/secrets/` (T031)
4. Network connectivity to cluster leader (for join mode)
### Enable First-Boot Automation
In your NixOS configuration:
```nix
# /etc/nixos/configuration.nix
{
imports = [
./nix/modules/first-boot-automation.nix
];
services.first-boot-automation = {
enable = true;
configFile = "/etc/nixos/secrets/cluster-config.json";
# Optional: disable specific services
enableChainfire = true;
enableFlareDB = true;
enableIAM = true;
enableHealthCheck = true;
};
}
```
### First Boot
After provisioning and reboot:
1. Node boots from disk
2. systemd starts services
3. First-boot automation runs automatically
4. Cluster join completes within 30-60 seconds
Check status:
```bash
systemctl status chainfire-cluster-join.service
systemctl status flaredb-cluster-join.service
systemctl status iam-initial-setup.service
systemctl status cluster-health-check.service
```
## Configuration
### cluster-config.json Format
```json
{
"node_id": "node01",
"node_role": "control-plane",
"bootstrap": true,
"cluster_name": "prod-cluster",
"leader_url": "https://node01.prod.example.com:2379",
"raft_addr": "10.0.1.10:2380",
"initial_peers": [
"node01:2380",
"node02:2380",
"node03:2380"
],
"flaredb_peers": [
"node01:2480",
"node02:2480",
"node03:2480"
]
}
```
### Required Fields
| Field | Type | Description |
|-------|------|-------------|
| `node_id` | string | Unique identifier for this node |
| `node_role` | string | Node role: `control-plane`, `worker`, or `all-in-one` |
| `bootstrap` | boolean | `true` for first 3 nodes, `false` for additional nodes |
| `cluster_name` | string | Cluster identifier |
| `leader_url` | string | HTTPS URL of cluster leader (used for join) |
| `raft_addr` | string | This node's Raft address (IP:port) |
| `initial_peers` | array | List of bootstrap peer addresses |
| `flaredb_peers` | array | List of FlareDB peer addresses |
### Optional Fields
| Field | Type | Description |
|-------|------|-------------|
| `node_ip` | string | Node's primary IP address |
| `node_fqdn` | string | Fully qualified domain name |
| `datacenter` | string | Datacenter identifier |
| `rack` | string | Rack identifier |
| `services` | object | Per-service configuration |
| `tls` | object | TLS certificate paths |
| `network` | object | Network CIDR ranges |
### Example Configurations
See [examples/](examples/) directory:
- `cluster-config-bootstrap.json` - Bootstrap node (first 3)
- `cluster-config-join.json` - Join node (additional)
- `cluster-config-all-in-one.json` - Single-node deployment
## Bootstrap vs Join
### Bootstrap Mode (bootstrap: true)
**When to use:**
- First 3 nodes in a new cluster
- Nodes configured with matching `initial_peers`
- No existing cluster to join
**Behavior:**
1. Services start with `--initial-cluster` configuration
2. Raft consensus automatically elects leader
3. Cluster join service detects bootstrap mode and exits immediately
4. Marker file created: `/var/lib/first-boot-automation/.chainfire-initialized`
**Example:**
```json
{
"node_id": "node01",
"bootstrap": true,
"initial_peers": ["node01:2380", "node02:2380", "node03:2380"]
}
```
### Join Mode (bootstrap: false)
**When to use:**
- Nodes joining an existing cluster
- Expansion or replacement nodes
- Leader is known and reachable
**Behavior:**
1. Service starts with no initial cluster config
2. Waits for local service to be healthy (max 120s)
3. POST to leader's `/admin/member/add` endpoint
4. Retries up to 5 times with 10s delay
5. Marker file created: `/var/lib/first-boot-automation/.chainfire-joined`
**Example:**
```json
{
"node_id": "node04",
"bootstrap": false,
"leader_url": "https://node01.prod.example.com:2379",
"raft_addr": "10.0.1.13:2380"
}
```
### Decision Matrix
| Scenario | bootstrap | initial_peers | leader_url |
|----------|-----------|---------------|------------|
| Node 1 (first) | `true` | all 3 nodes | self |
| Node 2 (first) | `true` | all 3 nodes | self |
| Node 3 (first) | `true` | all 3 nodes | self |
| Node 4+ (join) | `false` | all 3 nodes | node 1 |

```
## Troubleshooting
### Check Service Status
```bash
# Overall status
systemctl status chainfire-cluster-join.service
systemctl status flaredb-cluster-join.service
# Detailed logs with JSON output
journalctl -u chainfire-cluster-join.service -o json-pretty
# Follow logs in real-time
journalctl -u chainfire-cluster-join.service -f
```
### Common Issues
#### 1. Health Check Timeout
**Symptom:**
```json
{"level":"ERROR","message":"Health check timeout after 120s"}
```
**Causes:**
- Service not starting (check main service logs)
- Port conflict
- TLS certificate issues
**Solutions:**
```bash
# Check main service
systemctl status chainfire.service
journalctl -u chainfire.service
# Test health endpoint manually
curl -k https://localhost:2379/health
# Restart services
systemctl restart chainfire.service
systemctl restart chainfire-cluster-join.service
```
#### 2. Leader Unreachable
**Symptom:**
```json
{"level":"ERROR","message":"Join request failed: connection error"}
```
**Causes:**
- Network connectivity issues
- Firewall blocking ports
- Leader not running
- Wrong leader URL in config
**Solutions:**
```bash
# Test network connectivity
ping node01.prod.example.com
curl -k https://node01.prod.example.com:2379/health
# Check firewall
iptables -L -n | grep 2379
# Verify configuration
jq '.leader_url' /etc/nixos/secrets/cluster-config.json
# Try manual join (see below)
```
#### 3. Invalid Configuration
**Symptom:**
```json
{"level":"ERROR","message":"Configuration file not found"}
```
**Causes:**
- Missing configuration file
- Wrong file path
- Invalid JSON syntax
- Missing required fields
**Solutions:**
```bash
# Check file exists
ls -la /etc/nixos/secrets/cluster-config.json
# Validate JSON syntax
jq . /etc/nixos/secrets/cluster-config.json
# Check required fields
jq '.node_id, .bootstrap, .leader_url' /etc/nixos/secrets/cluster-config.json
# Fix and restart
systemctl restart chainfire-cluster-join.service
```
#### 4. Already Member (Reboot)
**Symptom:**
```json
{"level":"WARN","message":"Already member of cluster (HTTP 409)"}
```
**Explanation:**
- This is **normal** on reboots
- Marker file prevents duplicate joins
- No action needed
**Verify:**
```bash
# Check marker file
cat /var/lib/first-boot-automation/.chainfire-joined
# Should show timestamp: 2025-12-10T10:30:45+00:00
```
#### 5. Join Retry Exhausted
**Symptom:**
```json
{"level":"ERROR","message":"Failed to join cluster after 5 attempts"}
```
**Causes:**
- Persistent network issues
- Leader down or overloaded
- Invalid node configuration
- Cluster at capacity
**Solutions:**
```bash
# Check cluster status on leader
curl -k https://node01.prod.example.com:2379/admin/cluster/members | jq
# Verify this node's configuration
jq '.node_id, .raft_addr' /etc/nixos/secrets/cluster-config.json
# Increase retry attempts (edit NixOS config)
# Or perform manual join (see below)
```
### Verify Cluster Membership
**On leader node:**
```bash
# Chainfire members
curl -k https://localhost:2379/admin/cluster/members | jq
# FlareDB members
curl -k https://localhost:2479/admin/cluster/members | jq
```
**Expected output:**
```json
{
"members": [
{"id": "node01", "raft_addr": "10.0.1.10:2380", "status": "healthy"},
{"id": "node02", "raft_addr": "10.0.1.11:2380", "status": "healthy"},
{"id": "node03", "raft_addr": "10.0.1.12:2380", "status": "healthy"}
]
}
```
### Check Marker Files
```bash
# List all marker files
ls -la /var/lib/first-boot-automation/
# View timestamps
cat /var/lib/first-boot-automation/.chainfire-joined
cat /var/lib/first-boot-automation/.flaredb-joined
```
### Reset and Re-join
**Warning:** This will remove the node from the cluster and rejoin.
```bash
# Stop services
systemctl stop chainfire.service flaredb.service
# Remove data and markers
rm -rf /var/lib/chainfire/*
rm -rf /var/lib/flaredb/*
rm /var/lib/first-boot-automation/.chainfire-*
rm /var/lib/first-boot-automation/.flaredb-*
# Restart (will auto-join)
systemctl start chainfire.service
systemctl restart chainfire-cluster-join.service
```
## Manual Operations
### Manual Cluster Join
If automation fails, perform manual join:
**Chainfire:**
```bash
# On joining node, ensure service is running and healthy
curl -k https://localhost:2379/health
# From any node, add member to cluster
curl -k -X POST https://node01.prod.example.com:2379/admin/member/add \
-H "Content-Type: application/json" \
-d '{
"id": "node04",
"raft_addr": "10.0.1.13:2380"
}'
# Create marker to prevent auto-retry
mkdir -p /var/lib/first-boot-automation
date -Iseconds > /var/lib/first-boot-automation/.chainfire-joined
```
**FlareDB:**
```bash
curl -k -X POST https://node01.prod.example.com:2479/admin/member/add \
-H "Content-Type: application/json" \
-d '{
"id": "node04",
"raft_addr": "10.0.1.13:2480"
}'
date -Iseconds > /var/lib/first-boot-automation/.flaredb-joined
```
### Remove Node from Cluster
**On leader:**
```bash
# Chainfire
curl -k -X DELETE https://node01.prod.example.com:2379/admin/member/node04
# FlareDB
curl -k -X DELETE https://node01.prod.example.com:2479/admin/member/node04
```
**On removed node:**
```bash
# Stop services
systemctl stop chainfire.service flaredb.service
# Clean up data
rm -rf /var/lib/chainfire/*
rm -rf /var/lib/flaredb/*
rm /var/lib/first-boot-automation/.chainfire-*
rm /var/lib/first-boot-automation/.flaredb-*
```
### Disable First-Boot Automation
If you need to disable automation:
```nix
# In NixOS configuration
services.first-boot-automation.enable = false;
```
Or stop services temporarily:
```bash
systemctl stop chainfire-cluster-join.service
systemctl disable chainfire-cluster-join.service
```
### Re-enable After Manual Operations
After manual cluster operations:
```bash
# Create marker files to indicate join complete
mkdir -p /var/lib/first-boot-automation
date -Iseconds > /var/lib/first-boot-automation/.chainfire-joined
date -Iseconds > /var/lib/first-boot-automation/.flaredb-joined
# Or re-enable automation (will skip if markers exist)
systemctl enable --now chainfire-cluster-join.service
```
## Security
### TLS Certificates
**Requirements:**
- All cluster communication uses TLS
- Certificates must exist before first boot
- Generated by T031 TLS automation
**Certificate Paths:**
```
/etc/nixos/secrets/
├── ca.crt # CA certificate
├── node01.crt # Node certificate
└── node01.key # Node private key (mode 0600)
```
**Permissions:**
```bash
chmod 600 /etc/nixos/secrets/node01.key
chmod 644 /etc/nixos/secrets/node01.crt
chmod 644 /etc/nixos/secrets/ca.crt
```
### Configuration File Security
**Cluster configuration contains sensitive data:**
- IP addresses and network topology
- Service URLs
- Node identifiers
**Recommended permissions:**
```bash
chmod 600 /etc/nixos/secrets/cluster-config.json
chown root:root /etc/nixos/secrets/cluster-config.json
```
### Network Security
**Required firewall rules:**
```bash
# Chainfire
iptables -A INPUT -p tcp --dport 2379 -s 10.0.1.0/24 -j ACCEPT # API
iptables -A INPUT -p tcp --dport 2380 -s 10.0.1.0/24 -j ACCEPT # Raft
iptables -A INPUT -p tcp --dport 2381 -s 10.0.1.0/24 -j ACCEPT # Gossip
# FlareDB
iptables -A INPUT -p tcp --dport 2479 -s 10.0.1.0/24 -j ACCEPT # API
iptables -A INPUT -p tcp --dport 2480 -s 10.0.1.0/24 -j ACCEPT # Raft
# IAM
iptables -A INPUT -p tcp --dport 8080 -s 10.0.1.0/24 -j ACCEPT # API
```
### Production Considerations
**For production deployments:**
1. **Remove `-k` flag from curl** (validate TLS certificates)
2. **Implement mTLS** for client authentication
3. **Rotate credentials** regularly
4. **Audit logs** with structured logging
5. **Monitor health endpoints** continuously
6. **Backup cluster state** before changes
## Examples
### Example 1: 3-Node Bootstrap Cluster
**Node 1:**
```json
{
"node_id": "node01",
"bootstrap": true,
"raft_addr": "10.0.1.10:2380",
"initial_peers": ["node01:2380", "node02:2380", "node03:2380"]
}
```
**Node 2:**
```json
{
"node_id": "node02",
"bootstrap": true,
"raft_addr": "10.0.1.11:2380",
"initial_peers": ["node01:2380", "node02:2380", "node03:2380"]
}
```
**Node 3:**
```json
{
"node_id": "node03",
"bootstrap": true,
"raft_addr": "10.0.1.12:2380",
"initial_peers": ["node01:2380", "node02:2380", "node03:2380"]
}
```
**Provisioning:**
```bash
# Provision all 3 nodes simultaneously
for i in {1..3}; do
nixos-anywhere --flake .#node0$i root@node0$i.example.com &
done
wait
# Nodes will bootstrap automatically on first boot
```
### Example 2: Join Existing Cluster
**Node 4 (joining):**
```json
{
"node_id": "node04",
"bootstrap": false,
"leader_url": "https://node01.prod.example.com:2379",
"raft_addr": "10.0.1.13:2380"
}
```
**Provisioning:**
```bash
nixos-anywhere --flake .#node04 root@node04.example.com
# Node will automatically join on first boot
```
### Example 3: Single-Node All-in-One
**For development/testing:**
```json
{
"node_id": "aio01",
"bootstrap": true,
"raft_addr": "10.0.2.10:2380",
"initial_peers": ["aio01:2380"],
"flaredb_peers": ["aio01:2480"]
}
```
**Provisioning:**
```bash
nixos-anywhere --flake .#aio01 root@aio01.example.com
```
## Integration with Other Systems
### T024 NixOS Modules
First-boot automation integrates with service modules:
```nix
{
imports = [
./nix/modules/chainfire.nix
./nix/modules/flaredb.nix
./nix/modules/first-boot-automation.nix
];
services.chainfire.enable = true;
services.flaredb.enable = true;
services.first-boot-automation.enable = true;
}
```
### T025 Observability
Health checks integrate with Prometheus:
```yaml
# prometheus.yml
scrape_configs:
- job_name: 'cluster-health'
static_configs:
- targets: ['node01:2379', 'node02:2379', 'node03:2379']
metrics_path: '/health'
```
### T031 TLS Certificates
Certificates generated by T031 are used automatically:
```bash
# On provisioning server
./tls/generate-node-cert.sh node01.example.com 10.0.1.10
# Copied during nixos-anywhere
# First-boot automation reads from /etc/nixos/secrets/
```
## Logs and Debugging
### Structured Logging
All logs are JSON-formatted:
```json
{
"timestamp": "2025-12-10T10:30:45+00:00",
"level": "INFO",
"service": "chainfire",
"operation": "cluster-join",
"message": "Successfully joined cluster"
}
```
### Query Examples
**All first-boot logs:**
```bash
journalctl -u "*cluster-join*" -u "*initial-setup*" -u "*health-check*"
```
**Errors only:**
```bash
journalctl -u chainfire-cluster-join.service | grep '"level":"ERROR"'
```
**Last boot only:**
```bash
journalctl -b -u chainfire-cluster-join.service
```
**JSON output for parsing:**
```bash
journalctl -u chainfire-cluster-join.service -o json | jq '.MESSAGE'
```
## Performance Tuning
### Timeout Configuration
Adjust timeouts in NixOS module:
```nix
services.first-boot-automation = {
enable = true;
# Override default ports if needed
chainfirePort = 2379;
flaredbPort = 2479;
};
```
### Retry Configuration
Modify retry logic in scripts:
```bash
# baremetal/first-boot/cluster-join.sh
MAX_ATTEMPTS=10 # Increase from 5
RETRY_DELAY=15 # Increase from 10s
```
### Health Check Interval
Adjust polling interval:
```bash
# In service scripts
sleep 10 # Increase from 5s for less aggressive polling
```
## Support and Contributing

## Component Breakdown
### 1. Netboot Configurations
Located in `nix/images/`, these NixOS configurations define the netboot environment:
#### `netboot-base.nix`
**Purpose**: Common base configuration for all profiles
**Key Features**:
- Extends `netboot-minimal.nix` from nixpkgs
- SSH server with root login (key-based only)
- Generic kernel with broad hardware support
- Disk management tools (disko, parted, cryptsetup, lvm2)
- Network configuration (DHCP, predictable interface names)
- Serial console support (ttyS0, tty0)
- Minimal system (no docs, no sound)
**Package Inclusions**:
```nix
disko, parted, gptfdisk # Disk management
cryptsetup, lvm2 # Encryption and LVM
e2fsprogs, xfsprogs # Filesystem tools
iproute2, curl, tcpdump # Network tools
vim, tmux, htop # System tools
```
**Kernel Configuration**:
```nix
boot.kernelPackages = pkgs.linuxPackages_latest;
boot.kernelParams = [
"console=ttyS0,115200"
"console=tty0"
"loglevel=4"
];
```
#### `netboot-control-plane.nix`
**Purpose**: Full control plane deployment
**Imports**:
- `netboot-base.nix` (base configuration)
- `../modules` (PlasmaCloud service modules)
**Service Inclusions**:
- Chainfire (ports 2379, 2380, 2381)
- FlareDB (ports 2479, 2480)
- IAM (port 8080)
- PlasmaVMC (port 8081)
- PrismNET (port 8082)
- FlashDNS (port 53)
- FiberLB (port 8083)
- LightningStor (port 8084)
- K8sHost (port 8085)
**Service State**: All services **disabled** by default via `lib.mkDefault false`
**Resource Limits** (for netboot environment):
```nix
MemoryMax = "512M"
CPUQuota = "50%"
```
#### `netboot-worker.nix`
**Purpose**: Compute-focused worker nodes
**Imports**:
- `netboot-base.nix`
- `../modules`
**Service Inclusions**:
- PlasmaVMC (VM management)
- PrismNET (SDN)
**Additional Features**:
- KVM virtualization support
- Open vSwitch for SDN
- QEMU and libvirt tools
- Optimized sysctl for VM workloads
**Performance Tuning**:
```nix
"fs.file-max" = 1000000;
"net.ipv4.ip_forward" = 1;
"net.core.netdev_max_backlog" = 5000;
```
#### `netboot-all-in-one.nix`
**Purpose**: Single-node deployment with all services
**Imports**:
- `netboot-base.nix`
- `../modules`
**Combines**: All features from control-plane + worker
**Use Cases**:
- Development environments
- Small deployments
- Edge locations
- POC installations
### 2. Flake Integration
The main `flake.nix` exposes netboot configurations:
```nix
nixosConfigurations = {
netboot-control-plane = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [ ./nix/images/netboot-control-plane.nix ];
};
netboot-worker = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [ ./nix/images/netboot-worker.nix ];
};
netboot-all-in-one = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [ ./nix/images/netboot-all-in-one.nix ];
};
};
```
### 3. Build Script
`build-images.sh` orchestrates the build process:
**Workflow**:
1. Parse command-line arguments (--profile, --output-dir)
2. Create output directories
3. For each profile:
- Build netboot ramdisk: `nix build ...netbootRamdisk`
- Build kernel: `nix build ...kernel`
- Copy artifacts (bzImage, initrd)
- Generate iPXE boot script
- Calculate and display sizes
4. Verify outputs (file existence, size sanity checks)
5. Copy to PXE server (if available)
6. Print summary
**Build Commands**:
```bash
nix build .#nixosConfigurations.netboot-$profile.config.system.build.netbootRamdisk
nix build .#nixosConfigurations.netboot-$profile.config.system.build.kernel
```
**Output Structure**:
```
artifacts/
├── control-plane/
│ ├── bzImage # ~10-30 MB
│ ├── initrd # ~100-300 MB
│ ├── netboot.ipxe # iPXE script
│ ├── build.log # Build log
│ ├── initrd-link # Nix result symlink
│ └── kernel-link # Nix result symlink
├── worker/
│ └── ... (same structure)
└── all-in-one/
└── ... (same structure)
```
## Integration Points
### T024 NixOS Modules
The netboot configurations leverage T024 service modules:
**Module Structure** (example: chainfire.nix):
```nix
{
options.services.chainfire = {
enable = lib.mkEnableOption "chainfire service";
port = lib.mkOption { ... };
raftPort = lib.mkOption { ... };
package = lib.mkOption { ... };
};
config = lib.mkIf cfg.enable {
users.users.chainfire = { ... };
systemd.services.chainfire = { ... };
};
}
```
**Package Availability**:
```nix
# In netboot-control-plane.nix
environment.systemPackages = with pkgs; [
chainfire-server # From flake overlay
flaredb-server # From flake overlay
# ...
];
```
### T032.S2 PXE Infrastructure
The build script integrates with the PXE server:
**Copy Workflow**:
```bash
# Build script copies to:
chainfire/baremetal/pxe-server/assets/nixos/
├── control-plane/
│ ├── bzImage
│ └── initrd
├── worker/
│ ├── bzImage
│ └── initrd
└── all-in-one/
├── bzImage
└── initrd
```
**iPXE Boot Script** (generated):
```ipxe
#!ipxe
kernel ${boot-server}/control-plane/bzImage init=/nix/store/*/init console=ttyS0,115200
initrd ${boot-server}/control-plane/initrd
boot
```
## Build Process Deep Dive
### NixOS Netboot Build Internals
1. **netboot-minimal.nix** (from nixpkgs):
- Provides base netboot functionality
- Configures initrd with kexec support
- Sets up squashfs for Nix store
2. **Our Extensions**:
- Add PlasmaCloud service packages
- Configure SSH for nixos-anywhere
- Include provisioning tools (disko, etc.)
- Customize kernel and modules
3. **Build Outputs**:
- **bzImage**: Compressed Linux kernel
- **initrd**: Squashfs-compressed initial ramdisk containing:
- Minimal NixOS system
- Nix store with service packages
- Init scripts for booting
### Size Optimization Strategies
**Current Optimizations**:
```nix
documentation.enable = false; # -50MB
documentation.nixos.enable = false; # -20MB
i18n.supportedLocales = [ "en_US" ]; # -100MB
```
**Additional Strategies** (if needed):
- Use `linuxPackages_hardened` (smaller kernel)
- Remove unused kernel modules
- Compress with xz instead of gzip
- On-demand package fetching from HTTP substituter
**Expected Sizes**:
- **Control Plane**: ~250-350 MB (initrd)
- **Worker**: ~150-250 MB (initrd)
- **All-in-One**: ~300-400 MB (initrd)
## Boot Flow
### From PXE to Running System
```
1. PXE Boot
├─ DHCP discovers boot server
├─ TFTP loads iPXE binary
└─ iPXE executes boot script
2. Netboot Download
├─ HTTP downloads bzImage (~20MB)
├─ HTTP downloads initrd (~200MB)
└─ kexec into NixOS installer
3. NixOS Installer (in RAM)
├─ Init system starts
├─ Network configuration (DHCP)
├─ SSH server starts
└─ Ready for nixos-anywhere
4. Installation (nixos-anywhere)
├─ SSH connection established
├─ Disk partitioning (disko)
├─ NixOS system installation
├─ Secret injection
└─ Bootloader installation
5. First Boot (from disk)
├─ GRUB/systemd-boot loads
├─ Services start (enabled)
├─ Cluster join (if configured)
└─ Running PlasmaCloud node
```
## Customization Guide
### Adding a New Service
**Step 1**: Create NixOS module
```nix
# nix/modules/myservice.nix
{ config, lib, pkgs, ... }:
{
options.services.myservice = {
enable = lib.mkEnableOption "myservice";
};
config = lib.mkIf cfg.enable {
systemd.services.myservice = { ... };
};
}
```
**Step 2**: Add to flake packages
```nix
# flake.nix
packages.myservice-server = buildRustWorkspace { ... };
```
**Step 3**: Include in netboot profile
```nix
# nix/images/netboot-control-plane.nix
environment.systemPackages = with pkgs; [
myservice-server
];
services.myservice = {
enable = lib.mkDefault false;
};
```
### Creating a Custom Profile
**Step 1**: Create new netboot configuration
```nix
# nix/images/netboot-custom.nix
{ config, pkgs, lib, ... }:
{
imports = [
./netboot-base.nix
../modules
];
# Your customizations
environment.systemPackages = [ ... ];
}
```
**Step 2**: Add to flake
```nix
# flake.nix
nixosConfigurations.netboot-custom = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [ ./nix/images/netboot-custom.nix ];
};
```
**Step 3**: Update build script
```bash
# build-images.sh
profiles_to_build=("control-plane" "worker" "all-in-one" "custom")
```
## Security Model
### Netboot Phase
**Risk**: Netboot image has root SSH access enabled
**Mitigations**:
1. **Key-based authentication only** (no passwords)
2. **Isolated provisioning VLAN**
3. **MAC address whitelist in DHCP**
4. **Firewall disabled only during install**
### Post-Installation
Services remain disabled until final configuration enables them:
```nix
# In installed system configuration
services.chainfire.enable = true; # Overrides lib.mkDefault false
```
### Secret Management
Secrets are **NOT** embedded in netboot images:
```nix
# During nixos-anywhere installation:
scp secrets/* root@target:/tmp/secrets/
# Installed system references:
services.chainfire.settings.tls = {
cert_path = "/etc/nixos/secrets/tls-cert.pem";
};
```
## Performance Characteristics
### Build Times
- **First build**: 30-60 minutes (downloads all dependencies)
- **Incremental builds**: 5-15 minutes (reuses cached artifacts)
- **With local cache**: 2-5 minutes
### Network Requirements
- **Initial download**: ~2GB (nixpkgs + dependencies)
- **Netboot download**: ~200-400MB per node
- **Installation**: ~500MB-2GB (depending on services)
### Hardware Requirements
**Build Machine**:
- CPU: 4+ cores recommended
- RAM: 8GB minimum, 16GB recommended
- Disk: 50GB free space
- Network: Broadband connection
**Target Machine**:
- RAM: 4GB minimum for netboot (8GB+ for production)
- Network: PXE boot support, DHCP
- Disk: Depends on disko configuration
## Testing Strategy
### Verification Steps
1. **Syntax Validation**:
```bash
nix flake check
```
2. **Build Test**:
```bash
./build-images.sh --profile control-plane
```
3. **Artifact Verification**:
```bash
file artifacts/control-plane/bzImage # Should be Linux kernel
file artifacts/control-plane/initrd # Should be compressed data
```
4. **PXE Boot Test**:
- Boot VM from netboot image
- Verify SSH access
- Check available tools (disko, parted, etc.)
5. **Installation Test**:
- Run nixos-anywhere on test target
- Verify successful installation
- Check service availability
## Troubleshooting Matrix
| Symptom | Possible Cause | Solution |
|---------|---------------|----------|
| Build fails | Missing flakes | Enable experimental-features |
| Large initrd | Too many packages | Remove unused packages |
| SSH fails | Wrong SSH key | Update authorized_keys |
| Boot hangs | Wrong kernel params | Check console= settings |
| No network | DHCP issues | Verify useDHCP = true |
| Service missing | Package not built | Check flake overlay |
## Future Enhancements
### Planned Improvements
1. **Image Variants**:
- Minimal installer (no services)
- Debug variant (with extra tools)
- Rescue mode (for recovery)
2. **Build Optimizations**:
- Parallel profile builds
- Incremental rebuild detection
- Binary cache integration
3. **Security Enhancements**:
- Per-node SSH keys
- TPM-based secrets
- Measured boot support
4. **Monitoring**:

# PlasmaCloud NixOS Image Builder
This directory contains tools and configurations for building bootable NixOS netboot images for bare-metal provisioning of PlasmaCloud infrastructure.
## Overview
The NixOS Image Builder generates netboot images (kernel + initrd) that can be served via PXE/iPXE to provision bare-metal servers with PlasmaCloud services. These images integrate with the T024 NixOS service modules and the T032.S2 PXE boot infrastructure.
## Architecture
The image builder produces three deployment profiles:
### 1. Control Plane (`netboot-control-plane`)
Full control plane deployment with all 8 PlasmaCloud services:
- **Chainfire**: Distributed configuration and coordination
- **FlareDB**: Time-series metrics and events database
- **IAM**: Identity and access management
- **PlasmaVMC**: Virtual machine control plane
- **PrismNET**: Software-defined networking controller
- **FlashDNS**: High-performance DNS server
- **FiberLB**: Layer 4/7 load balancer
- **LightningStor**: Distributed block storage
- **K8sHost**: Kubernetes hosting component
**Use Cases**:
- Multi-node production clusters (3+ control plane nodes)
- High-availability deployments
- Separation of control and data planes
### 2. Worker (`netboot-worker`)
Compute-focused deployment for running tenant workloads:
- **PlasmaVMC**: Virtual machine control plane
- **PrismNET**: Software-defined networking
**Use Cases**:
- Worker nodes in multi-node clusters
- Dedicated compute capacity
- Scalable VM hosting
### 3. All-in-One (`netboot-all-in-one`)
Single-node deployment with all 8 services:
- All services from Control Plane profile
- Optimized for single-node operation
**Use Cases**:
- Development/testing environments
- Small deployments (1-3 nodes)
- Edge locations
- Proof-of-concept installations
## Prerequisites
### Build Environment
- **NixOS** or **Nix package manager** installed
- **Flakes** enabled in Nix configuration
- **Git** access to PlasmaCloud repository
- **Sufficient disk space**: ~10GB for build artifacts
### Enable Nix Flakes
If not already enabled, add to `/etc/nix/nix.conf` or `~/.config/nix/nix.conf`:
```
experimental-features = nix-command flakes
```
### Build Dependencies
The build process automatically handles all dependencies, but ensure you have:
- Working internet connection (for Nix binary cache)
- ~4GB RAM minimum
- ~10GB free disk space
## Build Instructions
### Quick Start
Build all profiles:
```bash
cd /home/centra/cloud/baremetal/image-builder
./build-images.sh
```
Build a specific profile:
```bash
# Control plane only
./build-images.sh --profile control-plane
# Worker nodes only
./build-images.sh --profile worker
# All-in-one deployment
./build-images.sh --profile all-in-one
```
Custom output directory:
```bash
./build-images.sh --output-dir /srv/pxe/images
```
### Build Output
Each profile generates:
- `bzImage` - Linux kernel (~10-30 MB)
- `initrd` - Initial ramdisk (~100-300 MB)
- `netboot.ipxe` - iPXE boot script
- `build.log` - Build log for troubleshooting
Artifacts are placed in:
```
./artifacts/
├── control-plane/
│ ├── bzImage
│ ├── initrd
│ ├── netboot.ipxe
│ └── build.log
├── worker/
│ ├── bzImage
│ ├── initrd
│ ├── netboot.ipxe
│ └── build.log
└── all-in-one/
├── bzImage
├── initrd
├── netboot.ipxe
└── build.log
```
### Manual Build Commands
You can also build images directly with Nix:
```bash
# Build initrd
nix build .#nixosConfigurations.netboot-control-plane.config.system.build.netbootRamdisk
# Build kernel
nix build .#nixosConfigurations.netboot-control-plane.config.system.build.kernel
# Access artifacts
ls -lh result/
```
## Deployment
### Integration with PXE Server (T032.S2)
The build script automatically copies artifacts to the PXE server directory if it exists:
```
chainfire/baremetal/pxe-server/assets/nixos/
├── control-plane/
├── worker/
├── all-in-one/
├── bzImage-control-plane -> control-plane/bzImage
├── initrd-control-plane -> control-plane/initrd
├── bzImage-worker -> worker/bzImage
└── initrd-worker -> worker/initrd
```
### Manual Deployment
Copy artifacts to your PXE/HTTP server:
```bash
# Example: Deploy to nginx serving directory
sudo cp -r ./artifacts/control-plane /srv/pxe/nixos/
sudo cp -r ./artifacts/worker /srv/pxe/nixos/
sudo cp -r ./artifacts/all-in-one /srv/pxe/nixos/
```
### iPXE Boot Configuration
Reference the images in your iPXE boot script:
```ipxe
#!ipxe
set boot-server 10.0.0.2:8080
:control-plane
kernel http://${boot-server}/nixos/control-plane/bzImage init=/nix/store/*/init console=ttyS0,115200 console=tty0 loglevel=4
initrd http://${boot-server}/nixos/control-plane/initrd
boot
:worker
kernel http://${boot-server}/nixos/worker/bzImage init=/nix/store/*/init console=ttyS0,115200 console=tty0 loglevel=4
initrd http://${boot-server}/nixos/worker/initrd
boot
```
## Customization
### Adding Services
To add a service to a profile, edit the corresponding configuration:
```nix
# nix/images/netboot-control-plane.nix
environment.systemPackages = with pkgs; [
chainfire-server
flaredb-server
# ... existing services ...
my-custom-service # Add your service
];
```
### Custom Kernel Configuration
Modify `nix/images/netboot-base.nix`:
```nix
boot.kernelPackages = pkgs.linuxPackages_6_6; # Specific kernel version
boot.kernelModules = [ "my-driver" ]; # Additional modules
boot.kernelParams = [ "my-param=value" ]; # Additional kernel parameters
```
### Additional Packages
Add packages to the netboot environment:
```nix
# nix/images/netboot-base.nix
environment.systemPackages = with pkgs; [
# ... existing packages ...
# Your additions
python3
nodejs
custom-tool
];
```
### Hardware-Specific Configuration
See `examples/hardware-specific.nix` for hardware-specific customizations.
## Troubleshooting
### Build Failures
**Symptom**: Build fails with Nix errors
**Solutions**:
1. Check build log: `cat artifacts/PROFILE/build.log`
2. Verify Nix flakes are enabled
3. Update nixpkgs: `nix flake update`
4. Clear Nix store cache: `nix-collect-garbage -d`
### Missing Service Packages
**Symptom**: Error: "package not found"
**Solutions**:
1. Verify service is built: `nix build .#chainfire-server`
2. Check flake overlay: `nix flake show`
3. Rebuild all packages: `nix build .#default`
### Image Too Large
**Symptom**: Initrd > 500 MB
**Solutions**:
1. Remove unnecessary packages from `environment.systemPackages`
2. Disable documentation (already done in base config)
3. Use minimal kernel: `boot.kernelPackages = pkgs.linuxPackages_latest_hardened`
### PXE Boot Fails
**Symptom**: Server fails to boot netboot image
**Solutions**:
1. Verify artifacts are accessible via HTTP
2. Check iPXE script syntax
3. Verify kernel parameters in boot script
4. Check serial console output (ttyS0)
5. Ensure DHCP provides correct boot server IP
### SSH Access Issues
**Symptom**: Cannot SSH to netboot installer
**Solutions**:
1. Replace example SSH key in `nix/images/netboot-base.nix`
2. Verify network connectivity (DHCP, firewall)
3. Check SSH service is running: `systemctl status sshd`
## Configuration Reference
### Service Modules (T024 Integration)
All netboot profiles import PlasmaCloud service modules from `nix/modules/`:
- `chainfire.nix` - Chainfire configuration
- `flaredb.nix` - FlareDB configuration
- `iam.nix` - IAM configuration
- `plasmavmc.nix` - PlasmaVMC configuration
- `prismnet.nix` - PrismNET configuration
- `flashdns.nix` - FlashDNS configuration
- `fiberlb.nix` - FiberLB configuration
- `lightningstor.nix` - LightningStor configuration
- `k8shost.nix` - K8sHost configuration
Services are **disabled by default** in netboot images and enabled in final installed configurations.
### Netboot Base Configuration
Located at `nix/images/netboot-base.nix`, provides:
- SSH server with root access (key-based)
- Generic kernel with broad hardware support
- Disk management tools (disko, parted, cryptsetup, lvm2)
- Network tools (iproute2, curl, tcpdump)
- Serial console support (ttyS0, tty0)
- DHCP networking
- Minimal system configuration
### Profile Configurations
- `nix/images/netboot-control-plane.nix` - All 8 services
- `nix/images/netboot-worker.nix` - Compute services (PlasmaVMC, PrismNET)
- `nix/images/netboot-all-in-one.nix` - All services for single-node
## Security Considerations
### SSH Keys
**IMPORTANT**: The default SSH key in `netboot-base.nix` is an example placeholder. You MUST replace it with your actual provisioning key:
```nix
users.users.root.openssh.authorizedKeys.keys = [
"ssh-ed25519 AAAAC3Nza... your-provisioning-key@host"
];
```
Generate a new key:
```bash
ssh-keygen -t ed25519 -C "provisioning@plasmacloud"
```
### Network Security
- Netboot images have **firewall disabled** for installation phase
- Use isolated provisioning VLAN for PXE boot
- Implement MAC address whitelist in DHCP
- Enable firewall in final installed configurations
### Secrets Management
- Do NOT embed secrets in netboot images
- Use nixos-anywhere to inject secrets during installation
- Store secrets in `/etc/nixos/secrets/` on installed systems
- Use proper file permissions (0400 for keys)
## Next Steps
After building images:
1. **Deploy to PXE Server**: Copy artifacts to HTTP server
2. **Configure DHCP/iPXE**: Set up boot infrastructure (see T032.S2)
3. **Prepare Node Configurations**: Create per-node configs for nixos-anywhere
4. **Test Boot Process**: Verify PXE boot on test hardware
5. **Run nixos-anywhere**: Install NixOS on target machines
## Resources

# Legacy Baremetal VM Cluster
# QEMU Socket Networking VM Cluster
`baremetal/vm-cluster` is no longer the primary local validation path.
## Architecture
Use [`nix/test-cluster`](/home/centra/cloud/nix/test-cluster/README.md) for canonical local VM validation:
**Topology:** 4 QEMU VMs connected via multicast socket networking (230.0.0.1:1234)
```bash
nix run ./nix/test-cluster#cluster -- smoke
```
**VMs:**
1. **pxe-server** (192.168.100.1) - Provides DHCP/TFTP/HTTP services
2. **node01** (192.168.100.11) - Cluster node
3. **node02** (192.168.100.12) - Cluster node
4. **node03** (192.168.100.13) - Cluster node
This directory is kept only for the older manual T036 PXE and bare-metal style experiments.
**Network:** All VMs share L2 segment via QEMU multicast socket (no root privileges required)
## What remains here
## Files
- [`pxe-server/`](/home/centra/cloud/baremetal/vm-cluster/pxe-server): older PXE server configuration
- [`legacy/`](/home/centra/cloud/baremetal/vm-cluster/legacy/README.md): archived manual deployment, validation, and ad hoc QEMU launch scripts
- `node01.qcow2`, `node02.qcow2`, `node03.qcow2` - 100GB cluster node disks
- `pxe-server.qcow2` - 20GB PXE server disk
- `launch-pxe-server.sh` - PXE server startup script
- `launch-node01.sh`, `launch-node02.sh`, `launch-node03.sh` - Node startup scripts
- `pxe-server/` - PXE server configuration files
## Status
## MACs
- unsupported for regular development
- not the release-validation path
- retained only to preserve old manual experiments
- pxe-server: 52:54:00:00:00:01
- node01: 52:54:00:00:01:01
- node02: 52:54:00:00:01:02
- node03: 52:54:00:00:01:03
## Provisioning Flow
1. Start PXE server VM (Alpine Linux with dnsmasq)
2. Configure DHCP/TFTP/HTTP services
3. Deploy NixOS netboot artifacts
4. Start node VMs with PXE boot enabled
5. Nodes PXE boot and provision via nixos-anywhere

# Legacy Launch Scripts
These scripts are archived manual launch helpers from the older `baremetal/vm-cluster` workflow.
They are not the canonical test path and should not be used for normal validation.
Use the Nix-native harness instead:
```bash
nix run ./nix/test-cluster#cluster -- smoke
```
Notes:
- `deploy-all.sh` and `validate-cluster.sh` are preserved only for the retired PXE/manual flow
- some scripts assume local disk images or host networking setup that is no longer maintained
- Alpine-specific flows are treated as retired
- supporting artifacts such as `alpine-answers.txt` are no longer kept current

RaftとGossipプロトコルを用いた、クラスター管理のための数万台までスケールするKey-Value Storeを書いてほしいです。
- プログラミング言語：rust
- テストをちゃんと書きながら書くことを推奨する。
- クラスターへの参加/削除/障害検知を行う。
では、**「Raft（合意形成）」と「Gossip（情報の拡散）」を組み合わせた場合、具体的にどうデータが流れ、どうやってノードが動き出すのか**、その具体的なフローを解説します。
-----
### 前提：このシステムの役割分担
* **Control Plane (CP):** Raftで構成された3〜7台（Raftアルゴリズムでうまく合意が取れる範囲）のサーバー。情報の「正規の持ち主」。いなくなったら自動でWorker Nodesから昇格する。
* **Worker Nodes (VM/DB Hosts):** 数百〜数千台の実働部隊。CPのクライアント。
### 1\. データはどのように書き込まれるか？ (Write)
書き込みは **「必ず Control Plane の Raft Leader に対して」** 行います。Gossip経由での書き込みは（順序保証がないため）行いません。
例：「VM-A を Node-10 で起動したい」
1. **API Call:** 管理者（またはCLI）が、CPのAPIサーバーにリクエストを送ります。
2. **Raft Log:** CPのリーダーは、この変更を `Put(Key="/nodes/node-10/tasks/vm-a", Value="START")` としてRaftログに追加します。
3. **Commit:** 過半数のCPノードがログを保存したら「書き込み完了」と見なします。
ここまでは普通のDBと同じです。
### 2\. 各ノードはどのようにデータを取得し、通知を受けるか？ (Read & Notify)
ここが最大のポイントです。数千台のノードが「自分宛ての命令はないか？」と毎秒ポーリング（問い合わせ）すると、CPがDDoS攻撃を受けたようにパンクします。
ここで **「Watch（ロングポーリング）」** という仕組みを使います。
#### A. Watchによる通知と取得（これがメイン）
Kubernetesやetcdが採用している方式です。
1. **接続維持:** Node-10 は起動時に CP に対して `Watch("/nodes/node-10/")` というリクエストを送ります。
2. **待機:** CP は「Node-10 以下のキーに変更があるまで、レスポンスを返さずに接続を維持（ブロック）」します。
3. **イベント発火:** 先ほどの書き込み（VM起動命令）が発生した瞬間、CP は待機していた Node-10 への接続を通じて「更新イベント（Event: PUT, Key: ...vm-a, Value: START）」を即座にプッシュします。
4. **アクション:** Node-10 は通知を受け取り次第、VMを起動します。
**結論:** 「書き込み後の通知」は絶対に必要です。それを効率よくやるのが **Watch API** です。
-----
### 3\. じゃあ Gossip はどこで使うのか？
「Raft + Watch」で完結しそうに見えますが、10台以上のスケール、特にVM基盤のような動的な環境では **Gossip が以下の「3つの穴」を埋めるために不可欠** になります。
#### ① Nodeの死活監視・インベントリ管理（下り方向）
CPが「Node-10にVMを立てたい」と思ったとき、「そもそもNode-10は生きているのか？ IPは？ 空きメモリは？」という情報を知る必要があります。
* **Gossipの役割:** 各Worker Nodeは、Gossip（SWIMプロトコル）でお互いに、そしてCPに対して「自分は生きてるよ、IPはこれだよ」と喋り続けます。
* CPはこのGossip情報を聞いて、最新の「ノード一覧リスト（Memberlist）」をメモリ上に保持します。
#### ② サービスのディスカバリ（横方向）
DB基盤の場合、「DBノードA」が「DBノードB」と通信したいことがあります。いちいちCPに聞きに行くと遅いです。
* **Gossipの役割:** ノード同士で「私はここにいるよ」とGossipし合うことで、CPを介さずに直接通信相手を見つけられます。
#### ③ "Actual State"（現状）の報告（上り方向）
VMが起動した後、「起動しました」というステータスをどうCPに伝えるか。
* **Raftに書く:** 確実ですが、頻繁に変わるステータス（CPU使用率など）を全部Raftに書くとCPがパンクします。
* **Gossipで流す:** 「VM-Aは起動中、負荷50%」といった情報はGossipに乗せて、**「結果的にCPに伝わればいい」** という扱いにします。
-----
### 設計のまとめ：RaftとGossipの使い分け
これから作る「汎用管理DB（外部依存型）」は、以下のようなインターフェースを持つことになるでしょう。
| アクション | 通信方式 | 具体的なデータ例 |
| :--- | :--- | :--- |
| **命令 (Desired State)**<br>「こうなってほしい」 | **Raft + Watch**<br>(強整合性) | ・VMの起動/停止命令<br>・DBのデータ配置情報の変更<br>・パスワードや設定変更 |
| **現状 (Actual State)**<br>「今こうなってます」 | **Gossip**<br>(結果整合性) | ・ノードの生存確認 (Heartbeat)<br>・リソース使用率 (CPU/Mem)<br>・「VM起動完了」などのステータス |
| **通知 (Notification)** | **Watch (HTTP/gRPC Stream)** | ・「新しい命令が来たぞ！」というトリガー |
#### 実装のアドバイス
もし「etcdのようなもの」を自作されるなら、**「Serf (Gossip)」と「Raft」をライブラリとして組み込み、その上に「gRPCによるWatch付きのKVS API」を被せる** という構成になります。
これができれば、VM基盤は「Watchして、VMを起動して、Gossipでステータスを返すエージェント」を作るだけで済みますし、DB基盤も同様に作れます。非常にスケーラブルで美しい設計です。

## Dependencies on Other Tasks
### Prerequisites
None - this is the first step in T032 (Bare-Metal Provisioning)
### Next Steps
- **T032.S3**: Image Builder - Generate NixOS netboot images for each profile
- **T032.S4**: Provisioning Orchestrator - API-driven node lifecycle management
### Integration Points
- **FlareDB**: Node inventory and state storage
- **IAM**: Authentication for provisioning API
- **PlasmaVMC**: VM provisioning on bare-metal nodes
- **K8sHost**: Kubernetes node integration
## Testing Status
### What Can Be Tested Now
✅ Directory structure creation
✅ Configuration file syntax validation
✅ Service startup (DHCP, TFTP, HTTP)
✅ Firewall rules
✅ Boot script download
✅ iPXE bootloader download/build
### What Requires T032.S3
⏳ Actual bare-metal provisioning (needs NixOS images)
⏳ End-to-end boot flow (needs kernel/initrd)
⏳ Profile-specific deployments (needs profile configs)
## Quick Start Commands
```bash
# Install and setup
cd baremetal/pxe-server
sudo ./setup.sh --install --download --validate
# Configure NixOS (edit configuration.nix)
imports = [ ./baremetal/pxe-server/nixos-module.nix ];
services.centra-pxe-server.enable = true;
# ... (see QUICKSTART.md for full config)
# Deploy
sudo nixos-rebuild switch
# Test services
sudo ./setup.sh --test
# Boot a server
# - Configure BIOS for PXE boot
# - Connect to network
# - Power on
```
## Known Limitations
1. **No NixOS images yet**: T032.S3 will generate the actual boot images
2. **Single interface**: Module supports one network interface (can be extended)
3. **No HA built-in**: DHCP failover can be configured manually (example provided)
4. **No authentication**: Provisioning API will add auth in T032.S4
## Configuration Examples Provided
1. Basic single-subnet PXE server
2. PXE server with MAC-based auto-selection
3. Custom DHCP configuration
4. Multi-homed server (multiple interfaces)
5. High-availability with failover
6. HTTPS boot (secure boot)
7. Development/testing configuration
8. Production with monitoring
## Security Considerations
- DHCP is unauthenticated (normal for PXE)
- TFTP is unencrypted (normal for PXE)
- HTTP can be upgraded to HTTPS (documented)
- iPXE supports secure boot with embedded certificates (build from source)
- Network should be isolated (provisioning VLAN recommended)
- Firewall rules limit exposure (only necessary ports)
## Troubleshooting Resources
Comprehensive troubleshooting section in README.md covers:
- DHCP discovery issues
- TFTP timeout problems
- HTTP download failures
- Boot script errors
- Serial console debugging
- Common error messages
- Service health checks
- Network connectivity tests
## Performance Considerations
- **Concurrent boots**: ~500 MB per node (kernel + initrd)
- **Recommended**: 1 Gbps link for PXE server
- **10 concurrent boots**: ~5 Gbps burst (stagger or use 10 Gbps)
- **Disk space**: 5-10 GB recommended (multiple profiles + versions)
## Compliance with Requirements
| Requirement | Status | Notes |
|-------------|--------|-------|
| DHCP server config | ✅ | ISC DHCP with BIOS/UEFI detection |
| iPXE boot scripts | ✅ | Main menu + 3 profiles |
| HTTP server config | ✅ | Nginx with proper paths |
| NixOS module | ✅ | Complete systemd integration |
| Setup script | ✅ | Download/build/validate/test |

# PXE Server Quick Start Guide
This is a condensed guide for getting the PXE boot server running quickly.
## Prerequisites
- NixOS server
- Root access
- Network connectivity to bare-metal servers
## 5-Minute Setup
### 1. Run Setup Script
```bash
cd baremetal/pxe-server
sudo ./setup.sh --install --download --validate
```
### 2. Configure NixOS
Add to `/etc/nixos/configuration.nix`:
```nix
imports = [ /path/to/baremetal/pxe-server/nixos-module.nix ];
services.centra-pxe-server = {
enable = true;
interface = "eth0"; # YOUR NETWORK INTERFACE
serverAddress = "10.0.100.10"; # YOUR PXE SERVER IP
dhcp = {
subnet = "10.0.100.0"; # YOUR SUBNET
netmask = "255.255.255.0";
broadcast = "10.0.100.255";
range = {
start = "10.0.100.100"; # DHCP RANGE START
end = "10.0.100.200"; # DHCP RANGE END
};
router = "10.0.100.1"; # YOUR GATEWAY
};
};
```
### 3. Deploy
```bash
sudo nixos-rebuild switch
```
### 4. Verify
```bash
sudo ./setup.sh --test
```
You should see:
- TFTP server running
- HTTP server running
- DHCP server running
### 5. Boot a Server
1. Configure server BIOS for PXE boot
2. Connect to same network
3. Power on
4. Watch for boot menu
## Adding Nodes
### Quick Add (No Auto-Selection)
Just boot the server and select profile from menu.
### With Auto-Selection
1. Get MAC address from server
2. Edit `ipxe/boot.ipxe`, add line:
```ipxe
iseq ${mac} AA:BB:CC:DD:EE:FF && set profile worker && set hostname worker-05 && goto boot ||
```
3. Optionally add to `dhcp/dhcpd.conf`:
```conf
host worker-05 {
hardware ethernet AA:BB:CC:DD:EE:FF;
fixed-address 10.0.100.65;
option host-name "worker-05";
}
```
4. Restart DHCP: `sudo systemctl restart dhcpd4`
## Troubleshooting
### Server doesn't get IP
```bash
sudo tcpdump -i eth0 port 67 or port 68
sudo journalctl -u dhcpd4 -f
```
Check:
- DHCP server running on correct interface
- Network connectivity
- Firewall allows UDP 67/68
### Server gets IP but no bootloader
```bash
sudo tcpdump -i eth0 port 69
sudo journalctl -u atftpd -f
```
Check:
- TFTP server running
- Bootloaders exist: `ls /var/lib/tftpboot/`
- Firewall allows UDP 69
### iPXE loads but can't get boot script
```bash
curl http://localhost/boot/ipxe/boot.ipxe
sudo tail -f /var/log/nginx/access.log
```
Check:
- Nginx running
- boot.ipxe exists: `ls /var/lib/pxe-boot/ipxe/`
- Firewall allows TCP 80
### Boot script loads but can't get kernel
This is expected until T032.S3 (Image Builder) is complete.
Check: `ls /var/lib/pxe-boot/nixos/`
Should have:
- bzImage
- initrd
These will be generated by the image builder.
## Common Commands
```bash
# Check all services
sudo systemctl status dhcpd4 atftpd nginx
# View logs
sudo journalctl -u dhcpd4 -u atftpd -u nginx -f
# Test connectivity
curl http://localhost/health
tftp localhost -c get undionly.kpxe /tmp/test.kpxe
# Restart services
sudo systemctl restart dhcpd4 atftpd nginx
# Check firewall
sudo iptables -L -n | grep -E "67|68|69|80"
```
## Boot Profiles
- **control-plane**: All services (FlareDB, IAM, PlasmaVMC, K8sHost, etc.)
- **worker**: Compute services (K8sHost, PlasmaVMC, ChainFire)
- **all-in-one**: Everything on one node (testing/homelab)
## Next Steps
- Add more nodes (see "Adding Nodes" above)
- Wait for T032.S3 to generate NixOS boot images
- Configure monitoring for boot activity
- Set up DHCP relay for multi-segment networks

## Components
### 1. DHCP Server (ISC DHCP)
- **Purpose**: Assigns IP addresses and directs PXE clients to bootloader
- **Config**: `dhcp/dhcpd.conf`
- **Features**:
- BIOS/UEFI detection via option 93 (architecture type)
- Per-host configuration for fixed IP assignment
- Automatic next-server and filename configuration
### 2. TFTP Server (atftpd)
- **Purpose**: Serves iPXE bootloader files to PXE clients
- **Files served**:
- `undionly.kpxe` - BIOS bootloader
- `ipxe.efi` - UEFI x86-64 bootloader
- `ipxe-i386.efi` - UEFI x86 32-bit bootloader (optional)
### 3. HTTP Server (nginx)
- **Purpose**: Serves iPXE scripts and NixOS boot images
- **Config**: `http/nginx.conf`
- **Endpoints**:
- `/boot/ipxe/boot.ipxe` - Main boot menu script
- `/boot/nixos/bzImage` - NixOS kernel
- `/boot/nixos/initrd` - NixOS initial ramdisk
- `/health` - Health check endpoint
### 4. iPXE Boot Scripts
- **Main script**: `ipxe/boot.ipxe`
- **Features**:
- Interactive boot menu with 3 profiles
- MAC-based automatic profile selection
- Serial console support for remote management
- Detailed error messages and debugging options
### 5. NixOS Service Module
- **File**: `nixos-module.nix`
- **Purpose**: Declarative NixOS configuration for all services
- **Features**:
- Single configuration file for entire stack
- Firewall rules auto-configured
- Systemd service dependencies managed
- Directory structure auto-created
## Quick Start
### Prerequisites
- NixOS server with network connectivity
- Network interface on the same subnet as bare-metal servers
- Sufficient disk space (5-10 GB for boot images)
### Installation Steps
1. **Clone this repository** (or copy `baremetal/pxe-server/` to your NixOS system)
2. **Run the setup script**:
```bash
sudo ./setup.sh --install --download --validate
```
This will:
- Create directory structure at `/var/lib/pxe-boot`
- Download iPXE bootloaders from boot.ipxe.org
- Install boot scripts
- Validate configurations
3. **Configure network settings**:
Edit `nixos-module.nix` or create a NixOS configuration:
```nix
# /etc/nixos/configuration.nix
imports = [
/path/to/baremetal/pxe-server/nixos-module.nix
];
services.centra-pxe-server = {
enable = true;
interface = "eth0"; # Your network interface
serverAddress = "10.0.100.10"; # PXE server IP
dhcp = {
subnet = "10.0.100.0";
netmask = "255.255.255.0";
broadcast = "10.0.100.255";
range = {
start = "10.0.100.100";
end = "10.0.100.200";
};
router = "10.0.100.1";
};
# Optional: Define known nodes with MAC addresses
nodes = {
"52:54:00:12:34:56" = {
profile = "control-plane";
hostname = "control-plane-01";
ipAddress = "10.0.100.50";
};
};
};
```
4. **Deploy NixOS configuration**:
```bash
sudo nixos-rebuild switch
```
5. **Verify services are running**:
```bash
sudo ./setup.sh --test
```
6. **Add NixOS boot images** (will be provided by T032.S3):
```bash
# Placeholder - actual images will be built by image builder
# For testing, you can use any NixOS netboot image
sudo mkdir -p /var/lib/pxe-boot/nixos
# Copy bzImage and initrd to /var/lib/pxe-boot/nixos/
```
7. **Boot a bare-metal server**:
- Configure server BIOS to boot from network (PXE)
- Connect to same network segment
- Power on server
- Watch for DHCP discovery and iPXE boot menu
## Detailed Setup
### Option 1: NixOS Module (Recommended)
The NixOS module provides a declarative way to configure the entire PXE server stack.
**Advantages**:
- Single configuration file
- Automatic service dependencies
- Rollback capability
- Integration with NixOS firewall
**Configuration Example**:
See the NixOS configuration example in [Quick Start](#quick-start).
### Option 2: Manual Installation
For non-NixOS systems or manual setup:
1. **Install required packages**:
```bash
# Debian/Ubuntu
apt-get install isc-dhcp-server atftpd nginx curl
# RHEL/CentOS
yum install dhcp tftp-server nginx curl
```
2. **Run setup script**:
```bash
sudo ./setup.sh --install --download
```
3. **Copy configuration files**:
```bash
# DHCP configuration
sudo cp dhcp/dhcpd.conf /etc/dhcp/dhcpd.conf
# Edit to match your network
sudo vim /etc/dhcp/dhcpd.conf
# Nginx configuration
sudo cp http/nginx.conf /etc/nginx/sites-available/pxe-boot
sudo ln -s /etc/nginx/sites-available/pxe-boot /etc/nginx/sites-enabled/
```
4. **Start services**:
```bash
sudo systemctl enable --now isc-dhcp-server
sudo systemctl enable --now atftpd
sudo systemctl enable --now nginx
```
5. **Configure firewall**:
```bash
# UFW (Ubuntu)
sudo ufw allow 67/udp # DHCP
sudo ufw allow 68/udp # DHCP
sudo ufw allow 69/udp # TFTP
sudo ufw allow 80/tcp # HTTP
# firewalld (RHEL)
sudo firewall-cmd --permanent --add-service=dhcp
sudo firewall-cmd --permanent --add-service=tftp
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --reload
```
## Configuration
### DHCP Configuration
The DHCP server configuration is in `dhcp/dhcpd.conf`. Key sections:
**Network Settings**:
```conf
subnet 10.0.100.0 netmask 255.255.255.0 {
range 10.0.100.100 10.0.100.200;
option routers 10.0.100.1;
option domain-name-servers 10.0.100.1, 8.8.8.8;
next-server 10.0.100.10; # PXE server IP
# ...
}
```
**Boot File Selection** (automatic BIOS/UEFI detection):
```conf
if exists user-class and option user-class = "iPXE" {
filename "http://10.0.100.10/boot/ipxe/boot.ipxe";
} elsif option architecture-type = 00:00 {
filename "undionly.kpxe"; # BIOS
} elsif option architecture-type = 00:07 {
filename "ipxe.efi"; # UEFI x86-64
}
```
**Host-Specific Configuration**:
```conf
host control-plane-01 {
hardware ethernet 52:54:00:12:34:56;
fixed-address 10.0.100.50;
option host-name "control-plane-01";
}
```
### iPXE Boot Script
The main boot script is `ipxe/boot.ipxe`. It provides:
1. **MAC-based automatic selection**:
```ipxe
iseq ${mac} 52:54:00:12:34:56 && set profile control-plane && goto boot ||
```
2. **Interactive menu** (if no MAC match):
```ipxe
:menu
menu Centra Cloud - Bare-Metal Provisioning
item control-plane 1. Control Plane Node (All Services)
item worker 2. Worker Node (Compute Services)
item all-in-one 3. All-in-One Node (Testing/Homelab)
```
3. **Kernel parameters**:
```ipxe
set kernel-params centra.profile=${profile}
set kernel-params ${kernel-params} centra.hostname=${hostname}
set kernel-params ${kernel-params} console=tty0 console=ttyS0,115200n8
```
### Adding New Nodes
To add a new node to the infrastructure:
1. **Get the MAC address** from the server (check BIOS or network card label)
2. **Add to MAC mappings** (`ipxe/mac-mappings.txt`):
```
52:54:00:12:34:5d worker worker-04
```
3. **Update boot script** (`ipxe/boot.ipxe`):
```ipxe
iseq ${mac} 52:54:00:12:34:5d && set profile worker && set hostname worker-04 && goto boot ||
```
4. **Add DHCP host entry** (`dhcp/dhcpd.conf`):
```conf
host worker-04 {
hardware ethernet 52:54:00:12:34:5d;
fixed-address 10.0.100.64;
option host-name "worker-04";
}
```
5. **Restart DHCP service**:
```bash
sudo systemctl restart dhcpd4
```
## Boot Profiles
### 1. Control Plane Profile
**Purpose**: Nodes that run core infrastructure services
**Services included**:
- FlareDB (PD, Store, TiKV-compatible database)
- IAM (Identity and Access Management)
- PlasmaVMC (Virtual Machine Controller)
- K8sHost (Kubernetes node agent)

- Monitoring (Prometheus, Grafana)
**Resource requirements**:
- CPU: 8+ cores recommended
- RAM: 32+ GB recommended
- Disk: 500+ GB SSD
**Use case**: Production control plane nodes in a cluster
### 2. Worker Profile
**Purpose**: Nodes that run customer workloads
**Services included**:
- K8sHost (Kubernetes node agent) - primary service
- PlasmaVMC (Virtual Machine Controller) - VM workloads
- ChainFire (Network policy enforcement)
- FlashDNS (Local DNS caching)
- Basic monitoring agents
**Resource requirements**:
- CPU: 16+ cores recommended

**Purpose**: Single-node deployment for testing and development
**Services included**:
- Complete Centra Cloud stack on one node
- All services from control-plane profile
- Suitable for testing, development, homelab
**Resource requirements**:
- CPU: 16+ cores recommended
- RAM: 64+ GB recommended
- Disk: 1+ TB SSD
**Use case**: Development, testing, homelab deployments
**Warning**: Not recommended for production use (no HA, resource intensive)
## Network Requirements
### Network Topology
The PXE server must be on the same network segment as the bare-metal servers, or you must configure DHCP relay.
**Same Segment** (recommended for initial setup):
```
┌──────────────┐ ┌──────────────────┐
│ PXE Server │ │ Bare-Metal Srv │
│ 10.0.100.10 │◄────────┤ (DHCP client) │
└──────────────┘ L2 SW └──────────────────┘
```
**Different Segments** (requires DHCP relay):
```
┌──────────────┐ ┌──────────┐ ┌──────────────────┐
│ PXE Server │ │ Router │ │ Bare-Metal Srv │
│ 10.0.100.10 │◄────────┤ (relay) │◄────────┤ (DHCP client) │
└──────────────┘ └──────────┘ └──────────────────┘
Segment A ip helper Segment B
```
### DHCP Relay Configuration
If your PXE server is on a different network segment:
**Cisco IOS**:
```
interface vlan 100
ip helper-address 10.0.100.10
```
**Linux (dhcp-helper)**:
```bash
apt-get install dhcp-helper
# Edit /etc/default/dhcp-helper
DHCPHELPER_OPTS="-s 10.0.100.10"
systemctl restart dhcp-helper
```
**Linux (dhcrelay)**:
```bash
apt-get install isc-dhcp-relay
dhcrelay -i eth0 -i eth1 10.0.100.10
```
### Firewall Rules
The following ports must be open on the PXE server:
| Port | Protocol | Service | Direction | Description |
|------|----------|---------|-----------|-------------|
| 67 | UDP | DHCP | Inbound | DHCP server |
| 68 | UDP | DHCP | Outbound | DHCP client responses |
| 69 | UDP | TFTP | Inbound | TFTP bootloader downloads |
| 80 | TCP | HTTP | Inbound | iPXE scripts and boot images |
| 443 | TCP | HTTPS | Inbound | Optional: secure boot images |
### Network Bandwidth
Estimated bandwidth requirements:
- Per-node boot: ~500 MB download (kernel + initrd)
- Concurrent boots: Multiply by number of simultaneous boots
- Recommended: 1 Gbps link for PXE server
Example: Booting 10 nodes simultaneously requires ~5 Gbps throughput burst, so stagger boots or use 10 Gbps link.
## Troubleshooting
### DHCP Issues
**Problem**: Server doesn't get IP address
**Diagnosis**:
```bash
# On PXE server, monitor DHCP requests
sudo tcpdump -i eth0 -n port 67 or port 68
# Check DHCP server logs
sudo journalctl -u dhcpd4 -f
# Verify DHCP server is running
sudo systemctl status dhcpd4
```
**Common causes**:
- DHCP server not running on correct interface
- Firewall blocking UDP 67/68
- Network cable/switch issue
- DHCP range exhausted
**Solution**:
```bash
# Check interface configuration
ip addr show
# Verify DHCP config syntax
sudo dhcpd -t -cf /etc/dhcp/dhcpd.conf
# Check firewall
sudo iptables -L -n | grep -E "67|68"
# Restart DHCP server
sudo systemctl restart dhcpd4
```
### TFTP Issues
**Problem**: PXE client gets IP but fails to download bootloader
**Diagnosis**:
```bash
# Monitor TFTP requests
sudo tcpdump -i eth0 -n port 69
# Check TFTP server logs
sudo journalctl -u atftpd -f
# Test TFTP locally
tftp localhost -c get undionly.kpxe /tmp/test.kpxe
```
**Common causes**:
- TFTP server not running
- Bootloader files missing
- Permissions incorrect
- Firewall blocking UDP 69
**Solution**:
```bash
# Check files exist
ls -la /var/lib/tftpboot/
# Fix permissions
sudo chmod 644 /var/lib/tftpboot/*.{kpxe,efi}
# Restart TFTP server
sudo systemctl restart atftpd
# Check firewall
sudo iptables -L -n | grep 69
```
### HTTP Issues
**Problem**: iPXE loads but can't download boot script or kernel
**Diagnosis**:
```bash
# Monitor HTTP requests
sudo tail -f /var/log/nginx/access.log
# Test HTTP locally
curl -v http://localhost/boot/ipxe/boot.ipxe
curl -v http://localhost/health
# Check nginx status
sudo systemctl status nginx
```
**Common causes**:
- Nginx not running
- Boot files missing
- Permissions incorrect
- Firewall blocking TCP 80
- Wrong server IP in boot.ipxe
**Solution**:
```bash
# Check nginx config
sudo nginx -t
# Verify files exist
ls -la /var/lib/pxe-boot/ipxe/
ls -la /var/lib/pxe-boot/nixos/
# Fix permissions
sudo chown -R nginx:nginx /var/lib/pxe-boot
sudo chmod -R 755 /var/lib/pxe-boot
# Restart nginx
sudo systemctl restart nginx
```
### Boot Script Issues
**Problem**: Boot menu appears but fails to load kernel
**Diagnosis**:
- Check iPXE error messages on console
- Verify URLs in boot.ipxe match actual paths
- Test kernel download manually:
```bash
curl -I http://10.0.100.10/boot/nixos/bzImage
```
**Common causes**:
- NixOS boot images not deployed yet (normal for T032.S2)
- Wrong paths in boot.ipxe
- Files too large (check disk space)
**Solution**:
```bash
# Wait for T032.S3 (Image Builder) to generate boot images
# OR manually place NixOS netboot images:
sudo mkdir -p /var/lib/pxe-boot/nixos
# Copy bzImage and initrd from NixOS netboot
```
### Serial Console Debugging
For remote debugging without physical access:
1. **Enable serial console in BIOS**:
- Configure COM1/ttyS0 at 115200 baud
- Enable console redirection
2. **Connect via IPMI SOL** (if available):
```bash
ipmitool -I lanplus -H <bmc-ip> -U admin sol activate
```
3. **Watch boot process**:
- DHCP discovery messages
- TFTP download progress
- iPXE boot menu
- Kernel boot messages
4. **Kernel parameters include serial console**:
```
console=tty0 console=ttyS0,115200n8
```
### Common Error Messages
| Error | Cause | Solution |
|-------|-------|----------|
| `PXE-E51: No DHCP or proxyDHCP offers were received` | DHCP server not responding | Check DHCP server running, network connectivity |
| `PXE-E53: No boot filename received` | DHCP not providing filename | Check dhcpd.conf has `filename` option |
| `PXE-E32: TFTP open timeout` | TFTP server not responding | Check TFTP server running, firewall rules |
| `Not found: /boot/ipxe/boot.ipxe` | HTTP 404 error | Check file exists, nginx config, permissions |
| `Could not boot: Exec format error` | Corrupted boot file | Re-download/rebuild bootloader |
## Advanced Topics
### Building iPXE from Source
For production deployments, building iPXE from source provides:
- Custom branding
- Embedded certificates for HTTPS
- Optimized size
- Security hardening
**Build instructions**:
```bash
sudo ./setup.sh --build-ipxe
```
Or manually:
```bash
git clone https://github.com/ipxe/ipxe.git
cd ipxe/src
# BIOS bootloader
make bin/undionly.kpxe
# UEFI bootloader
make bin-x86_64-efi/ipxe.efi
# Copy to PXE server
sudo cp bin/undionly.kpxe /var/lib/pxe-boot/ipxe/
sudo cp bin-x86_64-efi/ipxe.efi /var/lib/pxe-boot/ipxe/
```
### HTTPS Boot (Secure Boot)
For enhanced security, serve boot images over HTTPS:
1. **Generate SSL certificate**:
```bash
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
-keyout /etc/ssl/private/pxe-server.key \
-out /etc/ssl/certs/pxe-server.crt
```
2. **Configure nginx for HTTPS** (uncomment HTTPS block in `http/nginx.conf`)
3. **Update boot.ipxe** to use `https://` URLs
4. **Rebuild iPXE with embedded certificate** (for secure boot without prompts)
### Multiple NixOS Versions
To support multiple NixOS versions for testing/rollback:
```
/var/lib/pxe-boot/nixos/
├── 24.05/
│ ├── bzImage
│ └── initrd
├── 24.11/
│ ├── bzImage
│ └── initrd
└── latest -> 24.11/ # Symlink to current version
```
Update `boot.ipxe` to use `/boot/nixos/latest/bzImage` or add menu items for version selection.
### Integration with BMC/IPMI
For fully automated provisioning:
1. **Discover new hardware** via IPMI/Redfish API
2. **Configure PXE boot** via IPMI:
```bash
ipmitool -I lanplus -H <bmc-ip> -U admin chassis bootdev pxe options=persistent
```
3. **Power on server**:
```bash
ipmitool -I lanplus -H <bmc-ip> -U admin power on
```
4. **Monitor via SOL** (serial-over-LAN)
### Monitoring and Metrics
Track PXE boot activity:
1. **DHCP leases**:
```bash
cat /var/lib/dhcp/dhcpd.leases
```
2. **HTTP access logs**:
```bash
sudo tail -f /var/log/nginx/access.log | grep -E "boot.ipxe|bzImage|initrd"
```
3. **Prometheus metrics** (if nginx-module-vts installed):
- Boot file download counts
- Bandwidth usage
- Response times
4. **Custom metrics endpoint**:
- Parse nginx access logs
- Count boots per profile
- Alert on failed boots

# Notes
##############################################################################
# 1. Always update serverAddress, subnet, and interface to match your network
#
# 2. For MAC-based auto-selection, add nodes to the `nodes` attribute
#
# 3. DHCP failover requires configuration on both primary and secondary servers
#
# 4. HTTPS boot requires custom-built iPXE with embedded certificates
#
# 5. Test configurations in a development environment before production deployment
#
# 6. Keep DHCP lease database backed up for disaster recovery
#
# 7. Monitor DHCP pool utilization to avoid exhaustion
#
# 8. Use fixed IP addresses (via MAC mapping) for critical infrastructure nodes

# URL Mapping
# The following URLs are served by nginx:

# -> /var/lib/pxe-boot/ipxe/boot.ipxe
#
# http://10.0.100.10/boot/ipxe/undionly.kpxe

#
# http://10.0.100.10/boot/nixos/initrd
# -> /var/lib/pxe-boot/nixos/initrd
# File Sizes (Typical)
# - undionly.kpxe: ~100 KB
# - ipxe.efi: ~1 MB
# - boot.ipxe: ~10 KB (text script)
# - bzImage: ~10-50 MB (compressed kernel)
# - initrd: ~50-500 MB (depends on included tools/drivers)
# Permissions
# All files should be readable by the nginx user:
# chown -R nginx:nginx /var/lib/pxe-boot
# chmod -R 755 /var/lib/pxe-boot
# chmod 644 /var/lib/pxe-boot/ipxe/*
# chmod 644 /var/lib/pxe-boot/nixos/*
# Disk Space Requirements
# Minimum: 1 GB (for basic setup with one NixOS image)
# Recommended: 5-10 GB (for multiple profiles and versions)
# - Each NixOS profile: ~500 MB - 1 GB
# - Keep 2-3 versions for rollback: multiply by 2-3x
# - Add buffer for logs and temporary files
# Backup Recommendations
# - Boot scripts (ipxe/*.ipxe): Version control (git)
# - Bootloaders (ipxe/*.kpxe, *.efi): Can re-download, but keep backups
# - NixOS images: Can rebuild from S3 builder, but keep at least 2 versions
# - Configuration files: Version control (git)

# MAC Address to Profile Mappings
#
# This file documents the MAC address mappings used in boot.ipxe
# Update this file when adding new nodes to your infrastructure
#
# Format: MAC_ADDRESS PROFILE HOSTNAME
#
# To generate MAC addresses for virtual machines (testing):
# - Use the 52:54:00:xx:xx:xx range (QEMU/KVM local)
# - Or use your hypervisor's MAC assignment
#
# For physical servers:
# - Use the actual MAC address of the primary network interface
# - Usually found on a label on the server or in BIOS/BMC

#
# Then add to boot.ipxe:
# iseq ${mac} 52:54:00:12:34:5d && set profile worker && set hostname worker-04 && goto boot ||
