TRAFFIC_DIRECTOR: The core infrastructure of Google Cloud serves as the
Cloud Service Mesh control plane.
ISTIOD: managed instance of istiod serves as the Cloud Service Mesh
control plane.
UPDATING: The cluster is being migrated between implementations. Soon you
will have the TRAFFIC_DIRECTOR implementation.
If you don't see controlPlaneManagement.state: ACTIVE this means you don't
have a managed control plane. To confirm that you have an in-cluster control
plane, check for an istiod deployment in your istio-system namespace:
kubectl-nistio-systemgetdeployistiod
The output is similar to the following:
