Using CLI
Using CLI
To remediate the misconfiguration of not scheduling maintenance windows and exclusions in GCP using GCP CLI, follow these steps:Replace This command creates a maintenance policy for your GCP project, using the policy file This example sets a maintenance window for Monday at 3:00 AM, Tuesday at 8:00 AM, Wednesday at 3:00 PM, Thursday at 8:00 PM, and Friday at 12:00 PM. It also sets exclusions for January 1st, 2022 from 12:00 AM to 1:00 AM and for December 25th, 2022 for the entire day.This command updates the maintenance policy for your GCP project with your desired maintenance window and exclusions.This command displays the current maintenance policy for your GCP project.By following these steps, you can remediate the misconfiguration of not scheduling maintenance windows and exclusions in GCP using GCP CLI.
- Open the Cloud Shell in your GCP console.
- Run the following command to set up the default project for the Cloud Shell session:
[PROJECT_ID] with the ID of your GCP project.- Run the following command to create a maintenance policy for your GCP project:
maintenance-policy.yaml. You can modify this file to set up your desired maintenance window and exclusions.- Edit the
maintenance-policy.yamlfile to specify your desired maintenance window and exclusions. For example:
-
Save the
maintenance-policy.yamlfile. - Run the following command to update the maintenance policy for your GCP project:
- Verify that the maintenance policy has been updated by running the following command:

To remediate the “Schedule Maintenance Windows And Exclusions” misconfiguration in GCP using Python, you can follow the below steps:In the above code, you need to replace the In the above code, you need to replace the
- First, you need to enable the Compute Engine API in your GCP project. You can do this by navigating to the APIs & Services page in the GCP console and searching for “Compute Engine API”. Once you find it, click on the “Enable” button.
- Next, you need to install the Google Cloud SDK and the Python client library for Compute Engine. You can do this by following the instructions in the GCP documentation.
- Once you have installed the necessary tools, you can use the following Python code to create a maintenance window for a specific instance:
project, zone, instance, start_time, and end_time variables with your own values. This will create a maintenance window for the specified instance.- To exclude an instance from all maintenance windows, you can use the following Python code:
project, zone, and instance variables with your own values. This will exclude the specified instance from all maintenance windows.By following the above steps, you can remediate the “Schedule Maintenance Windows And Exclusions” misconfiguration in GCP using Python.
