Design doc for migrating External Secrets Operator off v0.12 (k8s <=1.31), now the ONLY remaining compat-gate blocker for autonomous k8s 1.35 (kyverno cleared to 1.18.1 today). Decisive findings: NO v1beta1->v1 conversion webhook, so all 104 ExternalSecrets (across 73 stacks) + 2 ClusterSecretStores must be rewritten to external-secrets.io/v1 (byte-identical apiVersion bump) while on 0.16.2, BEFORE crossing 0.17 (which removes v1beta1 — the point of no return). Step one minor at a time (no skipping); chart==app version; downstream Secrets survive. 5-phase ordered plan + per-phase rollback + the plan-time data.kubernetes_secret -target gotcha (15 stacks) + Tier-0/SOPS handling. Plan only — nothing applied. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |
