Traefik doesn't pick TLS certificates secrets from the ingress definition in Kubernetes

When I only add the TLS secret to the Ingress, Traefik serves it's default certificate.

kind: Ingress
spec:
  rules:
    ....
  tls:
  - secretName: ingress-mgt-server-keys

Only when I mount the secret and add below parameter, does Traefik start serving the real certificate.

entryPoints.https.tls.certificates

Are TLS secrets to be define in both Ingress and Ingress-controller? This forces me to repeat the keys as secrets to all the ingress namespaces as well as the ingress-controller namespace.

[Update]: Traefik has RBAC to read secrets from the target namespace.

Solution

  • The TLS Secret isn't needed to be set up in the target (ingress) namespaces.

    Only the ingress controller namespace needs the TLS Secret.
