9.2. Customizing labels and annotations

Procedure

1. Create a Knative service that contains the label or annotation that you want to propagate to the OpenShift Container Platform route:

   • To create a service by using YAML:

     Example service created by using YAML

     apiVersion: serving.knative.dev/v1
     kind: Service
     metadata:
       name: <service_name>
       labels:
         <label_name>: <label_value>
       annotations:
         <annotation_name>: <annotation_value>
     ...

   • To create a service by using the Knative (kn) CLI, enter:

     Example service created by using a kn command

     $ kn service create <service_name> \
       --image=<image> \
       --annotation <annotation_name>=<annotation_value> \
       --label <label_value>=<label_value>

2. Verify that the OpenShift Container Platform route has been created with the annotation or label that you added by inspecting the output from the following command:

   Example command for verification

   $ oc get routes.route.openshift.io \
        -l serving.knative.openshift.io/ingressName=<service_name> \ 

   1

   
        -l serving.knative.openshift.io/ingressNamespace=<service_namespace> \ 

   2

   
        -n knative-serving-ingress -o yaml \
            | grep -e "<label_name>: \"<label_value>\""  -e "<annotation_name>: <annotation_value>"
