This resource's status is\nupdated when the managed control plane is provisioned or fails provisioning and\ncontains an error message if enablement failed. \n\n```\nkubectl describe controlplanerevision -n istio-system\n```\n\nThe output is similar to: \n\n```\n Name: asm-managed\n\n …\n\n Status:\n Conditions:\n Last Transition Time: 2021-08-05T18:56:32Z\n Message: The provisioning process has not completed successfully\n Reason: NotProvisioned\n Status: False\n Type: Reconciled\n Last Transition Time: 2021-08-05T18:56:32Z\n Message: Provisioning has finished\n Reason: ProvisioningFinished\n Status: True\n Type: ProvisioningFinished\n Last Transition Time: 2021-08-05T18:56:32Z\n Message: Unsupported Kubernetes version: v1.14.10\n Reason: PreconditionFailed\n Status: True\n Type: Stalled\n```\n\nIf the `Type: Reconciled` `Status` field is `True`, then the control plane is\nrunning successfully. The `Type: Stalled` `Status` field will be `True` if\nthe managed control plane provisioning process has encountered an error.\nIf `Stalled`, the `Message` field will contain more information about\nthe specific error. See\n[Stalled codes](/service-mesh/docs/managed/troubleshoot-managed-anthos-service-mesh#stalled_codes)\nfor more information about possible errors.\n\nThe installation will be retried every 15 minutes, and the\n`ControlPlaneRevision` custom resource will be updated to reflect the latest\nstatus. However, the error message displayed in the Google Cloud console will not be\nupdated, even if installation later succeeds. Run the above command on your\ncluster to check current status (once every 15 minutes).\n\nIf the installation has not succeeded after addressing the error message and\nthen waiting 15 minutes, you can\n[Configure managed Cloud Service Mesh with `asmcli`](/service-mesh/v1.22/docs/onboarding/provision-control-plane)\nto enable Cloud Service Mesh.\n\nAlternatively, if the installation failed during GKE cluster\ncreation, you can delete the cluster and try again."]]
