oauth2-proxy is a leaf forward-auth service that depends on Keycloak + trusted wildcard TLS + split-horizon DNS. It lived in the gating `platform` Flux Kustomization (wait:true), so on a cold start it Failed until those dependencies existed, keeping the whole `platform` tier not-Ready. That in turn blocked `platform-config` — which brings up the very Keycloak instance, wildcard Certificate and L2 VIP oauth2-proxy needs (and previously carried oauth2-proxy's own httproute/servicemonitor) — from ever reconciling. A self-gating cold-start deadlock, twice-proven (DECISIONS-LOG sessions 7 & 9). Break the cycle by moving the whole oauth2-proxy component out of the `platform` tier into its own non-gating post-platform Flux Kustomization: - clusters/base/oauth2-proxy.yaml: new Kustomization -> ./platform/oauth2-proxy, dependsOn platform-config, wait:false, substituteFrom cluster-vars. - clusters/base/kustomization.yaml: reference the new Kustomization. - platform/kustomization.yaml: drop the oauth2-proxy component (no longer in the gating tier). - platform/oauth2-proxy/kustomization.yaml: pull in httproute + servicemonitor so the full component travels together. - platform-config/kustomization.yaml: drop the in-place oauth2-proxy httproute/servicemonitor refs (moved with the controller). - clusters/dev/kustomization.yaml: add the SOPS decryption patch for the new oauth2-proxy Kustomization (it now owns the encrypted credentials Secret that the `platform` Kustomization used to decrypt). Now `platform` reaches Ready without oauth2-proxy; platform-config brings up Keycloak/TLS/DNS; then oauth2-proxy reconciles against dependencies that already exist. wait:false guarantees its health can never gate anything above it. No config of oauth2-proxy itself changed — only its reconciliation tier. Co-Authored-By: Claude Opus 4.8 <[email protected]>
