1. Open the GCP Console and navigate to the Kubernetes Engine page.
2. Select the cluster that you want to reconfigure.
3. Click on the Edit button at the top of the page.
4. In the Edit Cluster page, scroll down to the Node Pools section.
5. Locate the alpha node pool and click on the trash can icon to delete it.
6. In the confirmation dialog box, click on Delete to confirm the deletion.
7. Once the alpha node pool is deleted, click on the Save button at the bottom of the page to save the changes.
8. Verify that the alpha node pool is no longer present in the cluster.

​

1. Firstly, ensure that you have the necessary permissions to access and modify the GCP resources.
2. Open the Cloud Shell in the GCP Console.
3. Run the below command to list all the available clusters in the current project:
   Copy

   Ask AI

   gcloud container clusters list
   

4. Identify the Alpha clusters that are being used for production.
5. Run the below command to upgrade the Alpha cluster to a stable version:
   Copy

   Ask AI

   gcloud container clusters upgrade [ALPHA_CLUSTER_NAME] --master --cluster-version=[STABLE_VERSION]
   

   Here, replace [ALPHA_CLUSTER_NAME] with the name of the Alpha cluster that needs to be upgraded, and [STABLE_VERSION] with the latest stable version of Kubernetes.
6. Once the upgrade is complete, run the below command to ensure that the cluster is no longer an Alpha cluster:
   Copy

   Ask AI

   gcloud container clusters describe [ALPHA_CLUSTER_NAME] --format="value(currentMasterVersion)"
   

   This command will return the current version of the cluster’s master. If it is not an Alpha version, then the upgrade was successful.
7. Finally, ensure that the upgraded cluster is not being used for production by updating the necessary configurations and policies.

1. First, you need to authenticate and authorize GCP APIs using the Python client library. You can use the below code snippet to authenticate and authorize the APIs:

from google.oauth2 import service_account
from googleapiclient.discovery import build

# Set the path of your service account credentials JSON file
SERVICE_ACCOUNT_FILE = 'path/to/your/credentials.json'

# Define the scopes for the APIs you will be using
SCOPES = ['https://www.googleapis.com/auth/cloud-platform']

# Authenticate and authorize the APIs using the credentials file and scopes
credentials = service_account.Credentials.from_service_account_file(
    SERVICE_ACCOUNT_FILE, scopes=SCOPES)
service = build('container', 'v1', credentials=credentials)

2. Once you have authenticated and authorized the APIs, you can use the list method of the projects.zones.clusters resource to retrieve the list of all the clusters in your GCP project. You can use the below code snippet to retrieve the list of all clusters:

# Set the project ID and zone where your clusters are located
project_id = 'your-project-id'
zone = 'us-central1-a'

# Retrieve the list of all clusters in the specified project and zone
clusters = service.projects().zones().clusters().list(
    projectId=project_id, zone=zone).execute()

3. After retrieving the list of all the clusters, you can iterate through each cluster and check if it is an alpha cluster by checking the status field of the cluster. If the status field is set to ALPHA, then it is an alpha cluster and needs to be remediated. You can use the below code snippet to iterate through each cluster and check its status:

# Iterate through each cluster and check its status
for cluster in clusters.get('clusters', []):
    if cluster.get('status', '').upper() == 'ALPHA':
        # Remediate the cluster by setting its node pool to a non-alpha version
        # You can use the below code snippet to update the node pool of the alpha cluster
        # to a non-alpha version
        node_pool = cluster['nodePools'][0]['name']
        body = {
            'name': node_pool,
            'version': '1.18.16-gke.502',
            'management': {
                'autoUpgrade': True,
                'autoRepair': True
            }
        }
        response = service.projects().zones().clusters().nodePools().update(
            projectId=project_id, zone=zone, clusterId=cluster['name'], nodePoolId=node_pool, body=body).execute()

4. Finally, you can verify that the alpha clusters have been remediated by checking their status again using the list method of the projects.zones.clusters resource. If the status of the alpha clusters has been changed to a non-alpha version, then the remediation has been successful.
