Resolving issues enabling Anthos Service Mesh through Google Cloud console

This section explains common Anthos Service Mesh problems and how to resolve them. If you need additional assistance, see Getting support.

Ensure you have sufficient permissions

To enable Anthos Service Mesh while creating a GKE cluster, you must have all of the following roles:

For information on granting roles, see Grant or revoke a single role.

Failed to enable Anthos Service Mesh through Google Cloud console

When enabling Anthos Service Mesh on a cluster, the enablement may fail. If the enablement fails, the Google Cloud console displays a message: "Anthos Service Mesh installation failed."

Enabling Anthos Service Mesh through the Google Cloud console creates a ControlPlaneRevision custom resource in the cluster. This resource's status is updated when the managed control plane is provisioned or fails provisioning and contains an error message if enablement failed.

kubectl describe controlplanerevision -n istio-system

The output is similar to:

    Name:         asm-managed

    …

        Status:                True
        Type:                  Stalled

If the Type: Reconciled Status field is True, then the control plane is running successfully. The Type: Stalled Status field will be True if the managed control plane provisioning process has encountered an error. If Stalled, the Message field will contain more information about the specific error. See Stalled codes for more information about possible errors.

The installation will be retried every 15 minutes, and the ControlPlaneRevision custom resource will be updated to reflect the latest status. However, the error message displayed in the Google Cloud console will not be updated, even if installation later succeeds. Run the above command on your cluster to check current status (once every 15 minutes).

If the installation has not succeeded after addressing the error message and then waiting 15 minutes, you can Configure managed Anthos Service Mesh with asmcli to enable Anthos Service Mesh.

Alternatively, if the installation failed during GKE cluster creation, you can delete the cluster and try again.
