6.11. Creating a route using the destination CA certificate in the Ingress annotation

Procedure

1. Create a secret for the destination CA certificate by entering the following command:

   $ oc create secret generic dest-ca-cert --from-file=tls.crt=<file_path>

   For example:

   $ oc -n test-ns create secret generic dest-ca-cert --from-file=tls.crt=tls.crt

   Example output

   secret/dest-ca-cert created

2. Add the route.openshift.io/destination-ca-certificate-secret to the Ingress annotations:

   apiVersion: networking.k8s.io/v1
   kind: Ingress
   metadata:
     name: frontend
     annotations:
       route.openshift.io/termination: "reencrypt"
       route.openshift.io/destination-ca-certificate-secret: secret-ca-cert 

   1

   
   ...

   1

   The annotation references a kubernetes secret.

3. The secret referenced in this annotation will be inserted into the generated route.

   Example output

   apiVersion: route.openshift.io/v1
   kind: Route
   metadata:
     name: frontend
     annotations:
       route.openshift.io/termination: reencrypt
       route.openshift.io/destination-ca-certificate-secret: secret-ca-cert
   spec:
   ...
     tls:
       insecureEdgeTerminationPolicy: Redirect
       termination: reencrypt
       destinationCACertificate: |
         -----BEGIN CERTIFICATE-----
         [...]
         -----END CERTIFICATE-----
