The ACME DNS-01 self-check resolved through CoreDNS and never saw the TXT
record. The wildcard renewal stalled on 2026-09-23 and riotpiao-com-tls
expired on 2026-10-23. Every Cloudflare Tunnel origin then failed with
"x509: certificate has expired or is not yet valid".
Changes:
- cert-manager: pin the self-check to the public resolvers with
--dns01-recursive-nameservers and --dns01-recursive-nameservers-only.
Verified against Let's Encrypt staging: the challenge went valid and the
certificate issued.
- comfyui and forgejo: drop the per-host tls blocks and the
cert-manager.io/cluster-issuer annotations. The wildcard covers both
hosts, and the per-host certificates (comfyui-tls, forgejo-tls) expired
with the wildcard.
- riotpiao-com-cert: document the wildcard as nginx's default certificate
and the zero-downtime renewal path.
Renewal now runs 30 days before expiry, writes the same secret, and nginx
hot-reloads without a pod restart.
GET /user/sign_up returned 200 — anyone reaching forgejo.riotpiao.com
could create an account. Add [service] DISABLE_REGISTRATION: true.
Admin-created accounts (UI/API) are unaffected.
GITEA__WEBHOOK__ALLOWED_HOST_LIST=external,api.riotpiao.com
api.riotpiao.com resolves to cluster ingress ClusterIP (private range)
which is blocked by Forgejo's default SSRF protection. Safe to allowlist
as it is our own api-gw.
Every workflow in the cluster has been silently dead. app.ini carried no
[actions] section, so Forgejo never created a run: the API returns
total_count: 0 for rock/homelab and rock/homelab-frontend alike, despite both
repos reporting has_actions: true, cluster-ci.yaml and build.yaml sitting on
their default branches, and forgejo-runner having registered successfully.
Registration does not go through the dispatcher, which is why the runner looks
healthy -- it logs "declared successfully" and "[poller 0] launched" and then
picks up nothing, forever. That reads like a runner or label problem and is
neither.
This also explains why the api-gateway images in the registry were all built
by hand: the pipeline that was supposed to build them has never once run.
Forgejo restarts on this values change; git and the container registry are
briefly unavailable.
Two Ingresses claim forgejo.riotpiao.com and nginx honours the older chart one,
so the annotation on the other never applied and OCI pushes over 1m got 413.
