VPC Service Controls for Managed Anthos Service Mesh

Managed Anthos Service Mesh supports VPC Service Controls (VPC-SC) as a generally available (GA) feature in the rapid channel, for GKE clusters with a release greater than or equal to 1.22.1-gke.100.

Note: At the moment only newly provisioned control planes support VPC-SC GA. We are gradually migrating the existing control planes and will provide instructions on how to identify whether a control plane has been migrated. If you want to determine whether an existing control plane has already been migrated, please contact support.

Before you begin

The VPC-SC org-policy and service perimeter are configured at the organization level. Ensure that you have been granted the proper roles for administering VPC-SC.

Set up your VPC-SC service perimeter

Create or update your service perimeter:

1. Add your cluster project(s) and fleet project to the service perimeter. Having a service mesh spread across multiple VPC-SC perimeters is not supported.

2. Add restricted services to the service perimeter.

   You must add specific services to the allowed and restricted services lists in the service perimeter, so that your Anthos Service Mesh cluster can access them. Access to these services is also restricted within your cluster's Virtual Private Cloud (VPC) network.

   Not adding these services may cause the Anthos Service Mesh installation to fail or to not function properly. For example, if you don't add the Mesh Configuration API to the service perimeter, the installation will fail and the workloads won't receive their Envoy configuration from the managed control plane.

   Console

   1. Follow the steps in Updating a service perimeter to edit the perimeter.
   2. Click on the Edit VPC Service Perimeter page.
   3. Under Restricted Services, Services to protect, click Add Services.
   4. On the Specify services to restrict dialog, click Filter services, and enter Mesh Configuration API.
   5. Select the service's checkbox.
   6. Click Add Mesh Configuration API.
   7. Repeat steps c - f, to add:
      • Cloud Service Mesh Certificate Authority API
      • GKE Hub API
      • Cloud IAM API
      • Cloud Monitoring API
      • Cloud Trace API
      • Cloud Monitoring API
      • Google Cloud Resource Manager API
      • Cloud Run API
      • Google Compute Engine API
      • Google Container Registry API
      • Artifact Registry API
      • Google Cloud Storage API
   8. Click Save.

   gcloud

   To update the list of restricted services, use the update command and specify the services to add as a comma-delimited list:

   gcloud access-context-manager perimeters update PERIMETER_NAME \
     --add-restricted-services=meshconfig.googleapis.com,meshca.googleapis.com,gkehub.googleapis.com,iam.googleapis.com,monitoring.googleapis.com,cloudtrace.googleapis.com,monitoring.googleapis.com,cloudresourcemanager.googleapis.com,run.googleapis.com,compute.googleapis.com,containerregistry.googleapis.com,artifactregistry.googleapis.com,storage.googleapis.com \
     --policy=POLICY_NAME

   Where:

   • PERIMETER_NAME is the name of the service perimeter that you want to update.

   • POLICY_NAME is the numeric name of your organization's access policy. For example, 330193482019.

3. Click on VPC Accessible services and set it to 'All restricted services', so that services restricted at the step above are still accessible from within the VPC-SC perimeter.

4. Unless you are installing Anthos Service Mesh from an in-perimeter network, add an ingress rule to allow the identity running the asmcli command access to the service perimeter.

   For more information, see Updating a service perimeter.

Install the managed Anthos Service Mesh in a VPC-SC perimeter

Follow the steps in Configure managed Anthos Service Mesh page. Then, verify the control plane has been successfully provisioned and there are no VPC-SC related errors.

Troubleshooting

Cannot create cluster with the latest GKE 1.22 image

There is a known issue preventing the creation of a cluster with the latest 1.22 image in a VPC-SC restricted environment. The workaround is to create this cluster first with the default GKE channel image, and then upgrade the image:

gcloud container clusters create CLUSTER \
  --region REGION \
  --release-channel=rapid \
  --workload-pool=PROJECT_ID.svc.id.goog \
  --project PROJECT_ID

gcloud container clusters upgrade CLUSTER \
  --region REGION \
  --master --cluster-version 1.22 \
  --project PROJECT_ID

Containers are not able to download their images.

This may happen if the images are located outside of the service perimeter. Either move the images to a bucket located inside the perimeter, or update the perimeter to add an Egress rule. Typically, the Egress rule may allow selected identities to access the Container Registry API, Artifact Registry API, and Cloud Storage API.

The Status field of the ControlPlaneRevision CRD displays VPC-SC errors

Run this command to get more info about the error:

gcloud logging read --project=PROJECT_ID \
'protoPayload.metadata.@type=type.googleapis.com/google.cloud.audit.VpcServiceControlAuditMetadata'

Where:

• PROJECT_ID is the project ID of the project encountering errors.
