K8s automatic node repair enabled remediation

Using Console

Using CLI

To remediate the misconfiguration “Automatic Node Repair Should Be Enabled” in GCP using GCP CLI, follow the steps below:

Open the Cloud Shell in your GCP console.
Run the following command to enable automatic node repair for all node pools in a specific cluster:

gcloud container clusters update [CLUSTER_NAME] --enable-autorepair

Replace [CLUSTER_NAME] with the name of the cluster where you want to enable automatic node repair.

If you want to enable automatic node repair for a specific node pool in a cluster, run the following command:

gcloud container node-pools update [NODE_POOL_NAME] --cluster [CLUSTER_NAME] --enable-autorepair

Replace [NODE_POOL_NAME] with the name of the node pool where you want to enable automatic node repair, and [CLUSTER_NAME] with the name of the cluster where the node pool is located.

Verify that automatic node repair is enabled by running the following command:

gcloud container node-pools describe [NODE_POOL_NAME] --cluster [CLUSTER_NAME] | grep autorepair

This command will show you the status of automatic node repair for the specified node pool.By following these steps, you can remediate the misconfiguration “Automatic Node Repair Should Be Enabled” in GCP using GCP CLI.

Using Python

To remediate the misconfiguration of “Automatic Node Repair Should Be Enabled” for GCP using Python, you can follow the below steps:

Import the necessary modules:

from googleapiclient import discovery
from oauth2client.client import GoogleCredentials

Set the project ID and zone where the misconfiguration exists:

project_id = 'YOUR_PROJECT_ID'
zone = 'YOUR_ZONE'

Create a client object to authenticate with the GCP API:

credentials = GoogleCredentials.get_application_default()
compute = discovery.build('compute', 'v1', credentials=credentials)

Get the instance group manager resource:

instance_group_manager = compute.instanceGroupManagers().get(project=project_id, zone=zone, instanceGroupManager='YOUR_INSTANCE_GROUP_MANAGER_NAME').execute()

Check if the “autoHealingPolicies” field exists in the instance group manager resource:

if 'autoHealingPolicies' not in instance_group_manager:
    instance_group_manager['autoHealingPolicies'] = []

Create an auto-healing policy dictionary object:

auto_healing_policy = {
    'healthCheck': 'YOUR_HEALTH_CHECK_URL',
    'initialDelaySec': 'YOUR_INITIAL_DELAY_IN_SECONDS',
    'maxUnavailable': 'YOUR_MAX_UNAVAILABLE_COUNT'
}

Append the auto-healing policy to the instance group manager’s “autoHealingPolicies” field:

instance_group_manager['autoHealingPolicies'].append(auto_healing_policy)

Update the instance group manager resource with the new auto-healing policy:

compute.instanceGroupManagers().update(project=project_id, zone=zone, instanceGroupManager='YOUR_INSTANCE_GROUP_MANAGER_NAME', body=instance_group_manager).execute()

By following these steps, you can remediate the misconfiguration of “Automatic Node Repair Should Be Enabled” for GCP using Python.
