K8s network policies engine remediation

Using Console

Using CLI

To remediate the misconfiguration “Clusters Should Have Network Policies Or Dataplane V2 Enabled” for GCP using GCP CLI, you can follow the below steps:

Open the GCP Cloud Shell.
Run the following command to enable the Dataplane V2 API:

gcloud beta container clusters update CLUSTER_NAME --zone=ZONE --update-addons=NetworkPolicy=ENABLED --enable-dataplane-v2

Replace CLUSTER_NAME with the name of your GCP cluster and ZONE with the zone in which the cluster is located.

After the command executes successfully, verify that the Dataplane V2 API is enabled by running the following command:

gcloud beta container clusters describe CLUSTER_NAME --zone=ZONE | grep -i dataplane

This command should return the output “dataplaneV2Enabled: true”.

To enable network policies for the cluster, run the following command:

gcloud beta container clusters update CLUSTER_NAME --zone=ZONE --update-addons=NetworkPolicy=ENABLED

Verify that network policies are enabled by running the following command:

gcloud beta container clusters describe CLUSTER_NAME --zone=ZONE | grep -i networkpolicy

This command should return the output “networkPolicyConfig: enabled: true”.After following these steps, the misconfiguration “Clusters Should Have Network Policies Or Dataplane V2 Enabled” should be remediated for your GCP cluster.

Using Python

To remediate the misconfiguration “Clusters Should Have Network Policies Or Dataplane V2 Enabled” in GCP using python, you can follow the below steps:

First, you need to authenticate to GCP using a service account. You can create a service account and download the key file from the GCP console.

from google.oauth2 import service_account
from google.cloud import container_v1

credentials = service_account.Credentials.from_service_account_file(
    'path/to/key.json')
client = container_v1.ClusterManagerClient(credentials=credentials)

Next, you need to get the list of clusters in the project.

project_id = 'your-project-id'
zone = 'us-central1-a' # replace with your desired zone
clusters = client.list_clusters(project_id, zone)

For each cluster, you need to check if network policies or dataplane v2 is enabled. If not, you need to enable it.

for cluster in clusters:
    name = cluster.name
    network_policy = cluster.network_policy
    datapath_provider = cluster.datapath_provider
    
    if not network_policy or datapath_provider != 'DATAPLANE_V2':
        # update the cluster
        update = container_v1.types.ClusterUpdate()
        update.name = name
        update.network_policy = container_v1.types.NetworkPolicy(enabled=True)
        update.datapath_provider = 'DATAPLANE_V2'
        operation = client.update_cluster(project_id, zone, name, update)
        print(f"Updated cluster {name}. Operation: {operation.operation_id}")

Finally, you can run the python script to remediate the misconfiguration.

Note: You need to have the necessary permissions to update the clusters in the project.
