+If you have not previously used cluster extensions, you may need to register the service provider with your subscription. You can check the status of the provider registration using the [az provider list][az-provider-list] command, as shown in the following example:
+
+```azurecli-interactive
+az provider list --query "[?contains(namespace,'Microsoft.KubernetesConfiguration')]" -o table
+```
+
+The *Microsoft.KubernetesConfiguration* provider should report as *Registered*, as shown in the following example output:
+
+```output
+Namespace                          RegistrationState    RegistrationPolicy
+---------------------------------  -------------------  --------------------
+Microsoft.KubernetesConfiguration  Registered           RegistrationRequired
+```
+
+If the provider shows as *NotRegistered*, register the provider using the [az provider register][az-provider-register] as shown in the following example:
+
+```azurecli-interactive
+az provider register --namespace Microsoft.KubernetesConfiguration
+```
