4.2. Installing Knative Serving by using YAML

Procedure

1. Create a file named serving.yaml and copy the following example YAML into it:

   apiVersion: operator.knative.dev/v1beta1
   kind: KnativeServing
   metadata:
       name: knative-serving
       namespace: knative-serving

2. Apply the serving.yaml file:

   $ oc apply -f serving.yaml

Verification

1. To verify the installation is complete, enter the following command:

   $ oc get knativeserving.operator.knative.dev/knative-serving -n knative-serving --template='{{range .status.conditions}}{{printf "%s=%s\n" .type .status}}{{end}}'

   Example output

   DependenciesInstalled=True
   DeploymentsAvailable=True
   InstallSucceeded=True
   Ready=True

   注記

   It may take a few seconds for the Knative Serving resources to be created.

   If the conditions have a status of Unknown or False, wait a few moments and then check again after you have confirmed that the resources have been created.

2. Check that the Knative Serving resources have been created:

   $ oc get pods -n knative-serving

   Example output

3. Check that the necessary networking components have been installed to the automatically created knative-serving-ingress namespace:

   $ oc get pods -n knative-serving-ingress
