The 2026-05-26 migration flipped the keel default force->patch and dropped match-tag from the inject-keel-annotations patch, but Kyverno's add-only mutate can't remove an annotation that's no longer listed -- 194 workloads kept a stale keel.sh/match-tag=true. Under it Keel cross-assigned images in multi-image pods: the blog's nginx<->nginx-exporter images were swapped and the site was down 2026-05-26 -> 06-01 (nginx received the exporter's -nginx.scrape-uri arg and CrashLoopBackOff'd); changedetection was silently swapped (app lost its /datastore PVC + env, ran ephemeral for days). - policy now sets keel.sh/match-tag=null (strips on admission, never re-added) - swept the annotation off all 194 existing workloads (kubectl, no pod restart) - AGENTS.md: documents the strip; post-mortem added blog + changedetection un-swapped via kubectl set image (TF-ignored images); both 2/2 and serving 200. Policy already applied via scripts/tg (Tier-1 PG state authoritative). [ci skip] Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |
