Check control plane implementation
Run the following command to identify your cluster's control plane implementation:
gcloud container fleet mesh describe --project FLEET_PROJECT_ID
The output is similar to the following:
...
membershipSpecs:
projects/746296320118/locations/us-central1/memberships/demo-cluster-1:
mesh:
management: MANAGEMENT_AUTOMATIC
membershipStates:
projects/746296320118/locations/us-central1/memberships/demo-cluster-1:
servicemesh:
controlPlaneManagement:
details:
- code: REVISION_READY
details: 'Ready: asm-managed'
state: ACTIVE
implementation: TRAFFIC_DIRECTOR
...
The possible values of the implementation
are:
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 theTRAFFIC_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 -n istio-system get deploy istiod
The output is similar to the following:
NAME READY UP-TO-DATE AVAILABLE AGE
istiod 1/1 1 1 20m
