1. Open the Google Kubernetes Engine (GKE) console.
2. Select the cluster for which you want to enable automatic node upgrades.
3. Click on the “Edit” button at the top of the page.
4. Scroll down to the “Node Pools” section and click on the “Default pool” or the pool for which you want to enable automatic node upgrades.
5. Under the “Auto-upgrade” section, select the checkbox next to “Enable auto-upgrade”.
6. Choose the desired maintenance window during which automatic node upgrades should be performed.
7. Click on the “Save” button at the bottom of the page to save the changes.

​

1. Open the terminal and login to your GCP account using the command:
   gcloud auth login
   
2. 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.
3. 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.
4. 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.

1. Import the necessary libraries:

from googleapiclient import discovery
from google.oauth2 import service_account

2. Set up the credentials:

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

3. Create a container client:

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

4. 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()

5. 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.')

6. Run the Python script to enable automatic node upgrades.
