Automatic Node Upgrades Should Be Enabled

More Info:

Ensures all Kubernetes cluster nodes have automatic upgrades enabled. Enabling automatic upgrades on nodes ensures that each node stays current with the latest version of the master branch, also ensuring that the latest security patches are installed to provide the most secure environment.

Using Console

Using CLI

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

Open the terminal and login to your GCP account using the command:
```
gcloud auth login
```
Set the project in which you want to enable automatic node upgrades using the command:
```
gcloud config set project PROJECT_ID
```
Replace PROJECT_ID with your GCP project ID.
Enable automatic node upgrades for the node pool using the command:
```
gcloud container node-pools update NODE_POOL_NAME --cluster=CLUSTER_NAME --enable-autoupgrade
```
Replace NODE_POOL_NAME with the name of the node pool for which you want to enable automatic node upgrades, and replace CLUSTER_NAME with the name of the cluster in which the node pool is present.
Verify that automatic node upgrades are enabled for the node pool using the command:
```
gcloud container node-pools describe NODE_POOL_NAME --cluster=CLUSTER_NAME | grep autoupgrade
```
This command will return the status of automatic node upgrades for the specified node pool.

By following the above steps, you can remediate the misconfiguration “Automatic Node Upgrades Should Be Enabled” in GCP using GCP CLI.

Using Python

To remediate the automatic node upgrades misconfiguration on GCP using Python, you can follow the below steps:

Import the necessary libraries:

from googleapiclient import discovery
from google.oauth2 import service_account

Set up the credentials:

credentials = service_account.Credentials.from_service_account_file(
    'path/to/your/credentials.json')

Create a container client:

container_client = discovery.build('container', 'v1', credentials=credentials)

Get the current cluster configuration:

project_id = 'your-project-id'
zone = 'your-zone'
cluster_id = 'your-cluster-id'

cluster = container_client.projects().zones().clusters().get(
    projectId=project_id,
    zone=zone,
    clusterId=cluster_id
).execute()

Check if automatic node upgrades are enabled:

if cluster['autoUpgradeEnabled']:
    print('Automatic node upgrades are already enabled.')
else:
    # Enable automatic node upgrades
    cluster['autoUpgradeEnabled'] = True

    # Update the cluster configuration
    operation = container_client.projects().zones().clusters().update(
        projectId=project_id,
        zone=zone,
        clusterId=cluster_id,
        body=cluster
    ).execute()

    print('Automatic node upgrades have been enabled.')

Run the Python script to enable automatic node upgrades.

Note: Make sure to replace the path/to/your/credentials.json, your-project-id, your-zone, and your-cluster-id with the appropriate values for your GCP environment.
