fix: backend tls default namespace by zhaohuabing · Pull Request #7987 · envoyproxy/gateway

zhaohuabing · 2026-01-19T08:47:51Z

Fixes: the default namespace for SecretObjectReference should be the owner namespace, not default.

The condition The Backend was not accepted: clientCertificateRef Secret is not located in the same namespace as Backend. Secret namespace: default does not match Backend namespace: httpbin-tls is wrong in the following example.

apiVersion: gateway.envoyproxy.io/v1alpha1
kind: Backend
metadata:
  name: httpbin-mtls-httpbin-tls-be
  namespace: httpbin-tls
  resourceVersion: "1768671158131743002"
  uid: 1cb357df-44b9-4204-87b0-dbeb4cf86b7d
spec:
  endpoints:
  - fqdn:
      hostname: httpbin-tls.httpbin-tls.svc.cluster.local
      port: 8443
  tls:
    caCertificateRefs:
    - group: ""
      kind: Secret
      name: httpbin-mtls-ssl
    clientCertificateRef:
      group: ""
      kind: Secret
      name: httpbin-mtls-ssl
      namespace: httpbin-tls
    insecureSkipVerify: false
  type: Endpoints
