From e5d8dadbd4158dd0f77b56c55ecdbe158ddf450e Mon Sep 17 00:00:00 2001 From: Jon Chery Date: Tue, 28 Jul 2026 13:01:28 +0000 Subject: [PATCH] =?UTF-8?q?feat(P56):=20IAM=20re-bootstrap=20live=20step?= =?UTF-8?q?=20=E2=80=94=20managed=20policy=20+=20OIDC=20role?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit D-095 RESOLVED. User provided fresh root credentials in .env.secrets; the run resumed and applied the IAM baseline against account 581513795199. Live actions (2026-07-28): 1. Converted spike_runner_policy.json from an inline user policy to a customer-managed policy acdl-spike-runner-policy (ARN arn:aws:iam::581513795199:policy/acdl-spike-runner-policy). The extended policy (5917 bytes) exceeded the 2048-byte inline limit; the managed-policy path supports 6144 bytes per version + 5 versions. Inline policy deleted; managed policy attached. 2. Re-created the acdl-act-runner-role OIDC role (CAP-022 — was gone since Phase 08). Trust policy permits root assume until go-gitea/gitea#36988 merges real OIDC federation. Same managed policy attached so the runner inherits spike-runner-equivalent permissions, no long-lived key needed. Grant verification (all OK): - cloudfront:ListDistributions — OK (0 items, stacks not yet deployed) - wafv2:ListWebAcls(CLOUDFRONT) — OK - lambda:ListFunctions — OK - dynamodb:DescribeTable(acdl-contracts) — ResourceNotFound (table not yet created — Phase 57 applies it; grant works, no AccessDenied) - ce:GetCostAndUsage (7-day window) — OK (7 results — Phase 59 queries the full window) - secretsmanager:ListSecrets — OK - sns:ListTopics — OK - iam:GetRole(acdl-act-runner-role) — OK terraform/bootstrap/apply_iam_baseline.py — new idempotent script that records the live step (create/version managed policy, attach to user + role, delete leftover inline, ensure runner role). Re-ran to confirm idempotency (created v2, deleted v1). .ciagent/IAM_POLICY.md — updated with the managed-policy note, the OIDC role ARN + trust policy, the grant verification table, and the D-095 resolution note. terraform/bootstrap/README.md — added the v1.11 Phase 56 section documenting apply_iam_baseline.py.
