+You can choose to use Cloud Run on GKE in place of installing Knative and Istio
+separately after the cluster has been created. This means that Cloud Run
+(Knative), Istio, and HTTP Load Balancing will be enabled on the cluster at
+create time and cannot be [installed or uninstalled](../../clusters/applications.md) separately.
