1. Log in to the Google Cloud Platform (GCP) Console at https://console.cloud.google.com/.
2. In the GCP Console, navigate to the “DNS” section by clicking on the menu icon in the top-left corner, then selecting “Networking” and finally “Cloud DNS”.
3. In the Cloud DNS dashboard, locate the affected DNS zone and click on its name to open its details.
4. In the DNS zone details, you will see a list of DNS records associated with that zone. Identify the record that was pointing to the deleted Load Balancer Storage Bucket.
5. Click on the checkbox next to the record to select it.
6. At the top of the DNS zone details page, click on the “Edit” button to enter the edit mode.
7. In the edit mode, locate the record that was pointing to the deleted Load Balancer Storage Bucket and delete it by clicking on the trash bin icon next to it.
8. Once the record is deleted, click on the “Add Record Set” button to add a new record.
9. In the “Add Record Set” form, provide the necessary details to recreate the record:
   • Type: Select the appropriate record type (e.g., A, CNAME, etc.) based on your requirements.
   • Name: Enter the name of the record (e.g., subdomain.example.com).
   • TTL (optional): Set the desired Time-to-Live value for the record.
   • Data: Enter the destination IP address or hostname for the record.
10. After entering the required details, click on the “Create” button to add the new record.
11. Verify that the new record has been successfully added to the DNS zone.
12. Repeat steps 8-11 if you have multiple records that need to be recreated.

​

1. Verify the deleted storage bucket:
   • Run the following command to check if the storage bucket is deleted:
     Copy

     Ask AI

     gsutil ls gs://<bucket-name>
     

   • If the bucket is deleted, it will return an error message stating that the bucket does not exist.
2. Restore the deleted storage bucket:
   • Run the following command to restore the deleted storage bucket:
     Copy

     Ask AI

     gsutil undelete gs://<bucket-name>
     

   • This command will restore the deleted bucket and its contents.
3. Verify the restored storage bucket:
   • Run the following command to check if the storage bucket is successfully restored:
     Copy

     Ask AI

     gsutil ls gs://<bucket-name>
     

   • If the bucket is restored, it will list the contents of the bucket without any error messages.
4. Update the Load Balancer configuration:
   • Go to the GCP Console and navigate to the Load Balancer configuration.
   • Update the backend service or target pool associated with the Load Balancer to use the restored storage bucket.
   • Ensure that the backend service or target pool is correctly configured to use the restored bucket for serving traffic.
5. Test the Load Balancer:
   • After updating the Load Balancer configuration, perform a test to ensure that the Load Balancer is functioning properly and serving traffic correctly.
   • You can use tools like curl or web browsers to access the Load Balancer’s URL and verify that the restored storage bucket is accessible.

1. Install the required dependencies:
   • Install the Google Cloud SDK by following the instructions provided in the official documentation: https://cloud.google.com/sdk/install
   • Install the Python client library for Google Cloud DNS using the following command:
     Copy

     Ask AI

     pip install google-cloud-dns
     

2. Authenticate with your GCP account:
   • Open a terminal or command prompt and run the following command to authenticate with your GCP account:
     Copy

     Ask AI

     gcloud auth login
     

3. Create a new storage bucket:
   • Determine the name for the new storage bucket that will be used by the Load Balancer.
   • Run the following command to create a new storage bucket:
     Copy

     Ask AI

     gsutil mb -l <bucket-location> gs://<bucket-name>
     

     Replace <bucket-location> with the desired location for the bucket (e.g., us-central1) and <bucket-name> with the chosen name for the bucket.
4. Update the Load Balancer configuration:
   • Use the Google Cloud DNS Python client library to programmatically update the Load Balancer configuration with the new storage bucket.
   • Import the necessary modules in your Python script:
     Copy

     Ask AI

     from google.cloud import dns
     

   • Authenticate with the Google Cloud DNS service:
     Copy

     Ask AI

     # Set the path to your service account key JSON file
     key_path = '/path/to/service-account-key.json'
     
     # Create a DNS client using the service account key
     client = dns.Client.from_service_account_json(key_path)
     

   • Retrieve the existing Load Balancer configuration:
     Copy

     Ask AI

     # Set the project ID and zone where the Load Balancer is located
     project_id = 'your-project-id'
     zone = 'your-zone'
     
     # Set the name of the Load Balancer
     load_balancer_name = 'your-load-balancer-name'
     
     # Retrieve the existing Load Balancer configuration
     load_balancer = client.get_managed_zone(project_id, zone, load_balancer_name)
     

   • Update the Load Balancer configuration with the new storage bucket:
     Copy

     Ask AI

     # Set the name of the new storage bucket
     new_bucket_name = 'your-new-bucket-name'
     
     # Update the Load Balancer configuration with the new storage bucket
     load_balancer.bucket_name = new_bucket_name
     
     # Update the Load Balancer configuration in Google Cloud DNS
     client.update_managed_zone(project_id, zone, load_balancer)
     

5. Verify the remediation:
   • Run the Python script and ensure that it executes without any errors.
   • Verify that the Load Balancer configuration has been updated with the new storage bucket by checking the Load Balancer settings in the Google Cloud DNS console.
