argocd-server ran --insecure (plain HTTP :8080) while its Helm-managed
Ingress set ssl-passthrough: true, which sends nginx's raw TLS handshake
straight to the pod - HTTP server can't complete a TLS handshake, nginx
logged 502 (peer closed connection in SSL handshake). Compounded by a
second, conflicting Ingress for the same host in
k8s/bootstrap/ingress/ingress.yaml - two Ingress objects on one host is
undefined nginx routing behavior. Disabled the Helm-managed Ingress
(enabled: false) so ingress.yaml's passthrough Ingress is the sole
source of truth, and set server.insecure: false so argocd-server
actually terminates TLS itself, matching passthrough's requirement.
homelab-ca was referenced by 6 manifests (authentik, forgejo-runner,
blackbox-exporter, management-service) as a CA trust ConfigMap but never
existed anywhere - not in git, not live in cluster. Generated a new
10-year self-signed root CA, wired it as a ClusterIssuer (cert-manager
namespace) and distributed the public cert as a ConfigMap to every
consuming namespace (iam, cicd, monitoring, sqs). Private key lives only
in the encrypted Secret. Widened cert-manager-issuers' directory include
glob rather than creating a new Application - destination.namespace is
just a fallback default on a plain directory source, not a transformer,
so it doesn't fight with each ConfigMap's own explicit namespace.
Also adds grafana-oidc secret (GF_AUTH_GENERIC_OAUTH_CLIENT_SECRET),
same pre-existing gap as grafana-admin - was meant to come from a deleted
manual script, value already available in .env.
CoreDNS rewrites *.riotpiao.com → ingress-nginx-controller but bootstrap
deployed as ingress-nginx-bootstrap-controller. Service alias makes both work.
- Add explicit tls block with riotpiao-com-tls secret
- Enables HTTPS access to https://forgejo.riotpiao.com
- Matches wildcard certificate (*.riotpiao.com)
The file comment mentioned TLS should be handled via default-ssl-certificate,
but explicit TLS blocks are needed for proper HTTPS routing.
Our Ingress objects intentionally omit per-rule tls: blocks (single wildcard
cert served via --default-ssl-certificate). nginx-ingress's normal ssl-redirect
setting only forces HTTPS 301 for hosts with an explicit TLS block on their own
Ingress resource - since none of ours do, plain http://*.riotpiao.com requests
were served directly instead of redirected, exposing every client-facing
console (forgejo, authentik, argocd, grafana, vault, etc.) over plaintext HTTP.
force-ssl-redirect forces the redirect globally regardless of per-ingress TLS
block presence. Verified fix works (tested via manual patch then reverted -
confirmed 308 redirects to https:// on forgejo/authentik/argocd) before
committing via GitOps.
- minio console ingress: minio-console -> minio-cluster-console:9090 (service renamed by operator)
- minio-api ingress: point to minio:9000 (restored once requestAutoCert disabled)
- minio tenant: requestAutoCert: false (MinIO was TLS-only internally, breaking
plain-HTTP clients like Vault's S3 backend - this was the real cause of the
Vault S3 hang)
- argocd ingress: moved from namespace cicd -> argocd (service lives in argocd
namespace; ingress in wrong namespace can never route, was returning 503)
- removed duplicate kmsvc ingress (sqs namespace already has management-service
ingress with proper TLS block for same host/backend)
Audit method: cross-checked every ingress backend.service.{name,port} against
actual Service objects in cluster. Found 3 broken backends out of 15 ingresses.
Wildcard cert was left on letsencrypt-staging; staging root is not
browser-trusted so HTTPS to *.riotpiao.com fails cert validation.
Switch issuerRef to letsencrypt-prod to issue a trusted wildcard.
