1. Open the Google Cloud Console and navigate to the GKE cluster that you want to remediate.
2. Click on the “Workloads” tab and select the workload that you want to run in the GKE Sandbox.
3. Click on the “Edit” button to open the workload configuration.
4. In the “Security” section of the configuration, enable the “Sandbox” option.
5. Click on the “Save” button to apply the changes.
6. Verify that the workload is now running in the GKE Sandbox by checking the “Status” column in the “Workloads” tab. The status should be “Running” with a green checkmark.
7. Repeat steps 2-6 for any other workloads that need to be remediated.

​

1. Firstly, check if there are any workloads running on GKE Sandbox that are untrusted. This can be done by running the following command in GCP CLI:
   Copy

   Ask AI

   gcloud alpha container node-pools describe [NODE_POOL_NAME] --cluster=[CLUSTER_NAME] --zone=[ZONE]
   

   Replace [NODE_POOL_NAME], [CLUSTER_NAME] and [ZONE] with the corresponding values for your GKE Sandbox.
2. If there are any workloads running on GKE Sandbox that are untrusted, create a new node pool with the appropriate security settings. This can be done by running the following command in GCP CLI:
   Copy

   Ask AI

   gcloud beta container node-pools create [NEW_NODE_POOL_NAME] --cluster=[CLUSTER_NAME] --zone=[ZONE] --sandbox=unconfined
   

   Replace [NEW_NODE_POOL_NAME], [CLUSTER_NAME] and [ZONE] with the corresponding values for your GKE Sandbox. The --sandbox=unconfined flag will create a new node pool with unrestricted sandboxing, which is suitable for running untrusted workloads.
3. Migrate the workloads from the old node pool to the new node pool. This can be done by running the following command in GCP CLI:
   Copy

   Ask AI

   kubectl drain [NODE_NAME] --ignore-daemonsets --delete-local-data
   

   Replace [NODE_NAME] with the name of the node that is running the untrusted workload. This command will safely evict all the pods running on the node.
4. Delete the old node pool. This can be done by running the following command in GCP CLI:
   Copy

   Ask AI

   gcloud beta container node-pools delete [NODE_POOL_NAME] --cluster=[CLUSTER_NAME] --zone=[ZONE]
   

   Replace [NODE_POOL_NAME], [CLUSTER_NAME] and [ZONE] with the corresponding values for your GKE Sandbox.

1. Install the necessary libraries:
   Copy

   Ask AI

   pip install google-auth google-auth-oauthlib google-auth-httplib2 google-cloud-container
   

2. Set the project ID and cluster name for which you want to enable GKE Sandbox.
   Copy

   Ask AI

   project_id = "your-project-id"
   cluster_name = "your-cluster-name"
   

3. Authenticate using your Google Cloud credentials:
   Copy

   Ask AI

   from google.oauth2 import service_account
   
   credentials = service_account.Credentials.from_service_account_file('path/to/your/credentials.json')
   

4. Enable GKE Sandbox for the cluster:
   Copy

   Ask AI

   from google.cloud import container_v1
   
   client = container_v1.ClusterManagerClient(credentials=credentials)
   
   cluster = client.get_cluster(project_id, "us-central1", cluster_name)
   
   if not cluster.sandbox_config:
       sandbox_config = container_v1.SandboxConfig(pod_sandbox_spec=container_v1.PodSandboxConfig())
       cluster.sandbox_config = sandbox_config
       update_request = container_v1.UpdateClusterRequest(cluster=cluster, update_mask={"paths": ["sandbox_config"]})
       operation = client.update_cluster(update_request)
       operation.result()
   

5. Verify that GKE Sandbox is enabled:
   Copy

   Ask AI

   cluster = client.get_cluster(project_id, "us-central1", cluster_name)
   
   if cluster.sandbox_config:
       print("GKE Sandbox is enabled for the cluster.")
   else:
       print("GKE Sandbox is not enabled for the cluster.")
