Using Console
Using Console
To remediate the misconfiguration “Ensure Alpha Clusters Are Not Used For Production” in GCP using GCP console, follow the below steps:
- Open the GCP Console and navigate to the Kubernetes Engine page.
- Select the cluster that you want to reconfigure.
- Click on the Edit button at the top of the page.
- In the Edit Cluster page, scroll down to the Node Pools section.
- Locate the alpha node pool and click on the trash can icon to delete it.
- In the confirmation dialog box, click on Delete to confirm the deletion.
- Once the alpha node pool is deleted, click on the Save button at the bottom of the page to save the changes.
- Verify that the alpha node pool is no longer present in the cluster.
Using CLI
Using CLI
To remediate the misconfiguration of using Alpha Clusters for Production in GCP, you can follow the below steps using GCP CLI:
- Firstly, ensure that you have the necessary permissions to access and modify the GCP resources.
- Open the Cloud Shell in the GCP Console.
-
Run the below command to list all the available clusters in the current project:
- Identify the Alpha clusters that are being used for production.
-
Run the below command to upgrade the Alpha cluster to a 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.
-
Once the upgrade is complete, run the below command to ensure that the cluster is no longer an Alpha cluster:
This command will return the current version of the cluster’s master. If it is not an Alpha version, then the upgrade was successful.
- Finally, ensure that the upgraded cluster is not being used for production by updating the necessary configurations and policies.
Using Python
Using Python
To remediate the misconfiguration “Ensure Alpha Clusters Are Not Used For Production” in GCP using Python, you can follow the below steps:
- 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:
- Once you have authenticated and authorized the APIs, you can use the
listmethod of theprojects.zones.clustersresource 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:
- 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
statusfield of the cluster. If thestatusfield is set toALPHA, 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:
- Finally, you can verify that the alpha clusters have been remediated by checking their status again using the
listmethod of theprojects.zones.clustersresource. If the status of the alpha clusters has been changed to a non-alpha version, then the remediation has been successful.
