In-cluster pods resolved forgejo.viktorbarzin.me to the public IP
(176.12.22.76) and hairpinned out through the WAN gateway, intermittently
timing out buildkit pushes from Woodpecker build pods (which, unlike
kubelet, don't use the per-node containerd Forgejo mirror). This silently
failed CI build-and-push for Forgejo-hosted repos (recruiter-responder
pipelines #15-#18 at the push step).
Add a CoreDNS `rewrite name exact forgejo.viktorbarzin.me
traefik.traefik.svc.cluster.local` so pods resolve to the Traefik ClusterIP
(reachable in-cluster, unlike the ETP=Local LB .203; the Service-name target
auto-tracks the ClusterIP so it can't rot on a Traefik renumber). Traefik's
*.viktorbarzin.me wildcard keeps SNI/TLS valid. Makes the per-pod
woodpecker-server hostAlias belt-and-suspenders.
Applied via targeted apply (coredns ConfigMap only, to avoid reconciling 7
unrelated pre-existing drifts in the stack) + verified:
- pod resolves forgejo.viktorbarzin.me -> 10.111.111.95 (Traefik ClusterIP)
- recruiter-responder pipeline #20 build-and-push succeeds via ClusterIP
Docs: networking.md (K8s cluster DNS path) + .claude/CLAUDE.md (forgejo
registry quick-ref). Advances beads code-yh33.
