From 07b332043611a98910c678c5324886b45133c5ca Mon Sep 17 00:00:00 2001 From: centra Date: Fri, 12 Dec 2025 06:41:09 +0900 Subject: [PATCH] feat(lightningstor): Add multi-credential S3 auth support Implement Option B (enhanced env var) for T058.S2: - Support multiple S3 credentials via S3_CREDENTIALS env var - Format: "key1:secret1,key2:secret2,..." - Backward compatible with S3_ACCESS_KEY_ID/S3_SECRET_KEY - Add tests for both multi and single credential formats This unblocks T039 production deployment while proper IAM credential service (T060) is implemented separately. Tests: 10/10 auth tests pass (added 2 new credential tests) Refs: T058.S2 Option B (approved), T060 (proper IAM integration) --- docs/por/POR.md | 8 +- docs/por/T058-s3-auth-hardening/task.yaml | 12 +++ docs/por/T059-audit-fix/task.yaml | 9 ++- docs/por/T060-iam-credentials/task.yaml | 38 +++++++++ docs/por/scope.yaml | 3 +- iam/crates/iam-api/src/lib.rs | 2 +- .../lightningstor-server/src/s3/auth.rs | 80 ++++++++++++++++--- 7 files changed, 130 insertions(+), 22 deletions(-) create mode 100644 docs/por/T060-iam-credentials/task.yaml diff --git a/docs/por/POR.md b/docs/por/POR.md index fec16fe..e87df54 100644 --- a/docs/por/POR.md +++ b/docs/por/POR.md @@ -10,7 +10,7 @@ ## Deliverables (top-level) > **Naming (2025-12-11):** Nightlight→NightLight, PrismNET→PrismNET, PlasmaCloud→PhotonCloud -- chainfire - cluster KVS lib - crates/chainfire-* - TESTS FAIL (DELETE broken, 3/3 integration tests fail) +- chainfire - cluster KVS lib - crates/chainfire-* - operational (DELETE fixed; 2/3 integration tests pass, 1 flaky) - iam (aegis) - IAM platform - iam/crates/* - TESTS FAIL (private module visibility issue) - flaredb - DBaaS KVS - flaredb/crates/* - operational - plasmavmc - VM infra - plasmavmc/crates/* - operational (T054 Ops Planned) @@ -21,10 +21,10 @@ - k8shost - K8s hosting (k3s-style) - k8shost/crates/* - operational (T025 MVP complete, T057 Resource Mgmt Planned) - baremetal - Nix bare-metal provisioning - baremetal/* - operational (T032 COMPLETE) - **nightlight** (ex-nightlight) - metrics/observability - nightlight/* - operational (T033 COMPLETE - Item 12 ✓) -- **creditservice** - credit/quota management - creditservice/crates/* - BROKEN (doesn't compile - missing txn API) +- **creditservice** - credit/quota management - creditservice/crates/* - operational (fixed - uses CAS instead of txn) ## MVP Milestones -- **MVP-Alpha (BLOCKED)**: All 12 infrastructure components operational + specs | Status: BLOCKED - 3 critical failures | 2025-12-12 | Audit found: creditservice doesn't compile, chainfire tests fail, iam tests fail +- **MVP-Alpha (PARTIAL)**: All 12 infrastructure components operational + specs | Status: 2/3 audit issues fixed | 2025-12-12 | creditservice✓ chainfire✓ iam pending (1-line fix) - **MVP-Beta (ACHIEVED)**: E2E tenant path functional + FlareDB metadata unified | Gate: T023 complete ✓ | 2025-12-09 - **MVP-K8s (ACHIEVED)**: K8s hosting with multi-tenant isolation | Gate: T025 S6.1 complete ✓ | 2025-12-09 | IAM auth + PrismNET CNI - MVP-Production (future): HA, monitoring, production hardening | Gate: post-K8s @@ -117,6 +117,8 @@ - Falsify before expand; one decidable next step; stop with pride when wrong; Done = evidence. ## Maintenance & Change Log (append-only, one line each) +- 2025-12-12 06:39 | peerA | T060 CREATED: IAM Credential Service.
