4. Enable Deletion Protection: In the cluster details page, click on the “Modify” button at the top right corner.
5. Enable Deletion Protection Option: Scroll down to the “Deletion protection” section in the Modify cluster settings page.
6. Enable Deletion Protection: Check the box next to “Enable deletion protection” to turn on deletion protection for the DocumentDB cluster.
7. Save Changes: Scroll down to the bottom of the page and click on the “Modify cluster” button to save the changes.
8. Verify Deletion Protection: Once the modification is completed, go back to the DocumentDB cluster details page and ensure that the deletion protection status is now enabled.

​

1. Install and Configure AWS CLI: If you haven’t already, install the AWS CLI and configure it with the necessary credentials by running:
   aws configure
   
   Follow the prompts to input your AWS Access Key ID, Secret Access Key, default region, and default output format.
2. Enable Deletion Protection for the DocumentDB Cluster: Run the following AWS CLI command to enable deletion protection for your DocumentDB cluster:
   aws docdb modify-db-cluster --db-cluster-identifier YOUR_CLUSTER_IDENTIFIER --deletion-protection
   
   Replace YOUR_CLUSTER_IDENTIFIER with the actual identifier of your DocumentDB cluster.
3. Verify the Deletion Protection Status: To verify that deletion protection has been successfully enabled for your DocumentDB cluster, you can describe the cluster using the following command:
   aws docdb describe-db-clusters --db-cluster-identifier YOUR_CLUSTER_IDENTIFIER
   
   Ensure that the DeletionProtection attribute in the output is set to true.

1. Install the AWS SDK for Python (boto3) if you haven’t already:

pip install boto3

2. Create a Python script with the following code to enable deletion protection for the DocumentDB cluster:

import boto3

# Initialize the DocumentDB client
client = boto3.client('docdb')

# Specify the DocumentDB cluster identifier
cluster_identifier = 'your-cluster-identifier'

# Enable deletion protection for the DocumentDB cluster
response = client.modify_db_cluster(
    DBClusterIdentifier=cluster_identifier,
    DeletionProtection=True
)

# Print the response
print(response)

3. Replace 'your-cluster-identifier' with the actual identifier of your DocumentDB cluster.
4. Run the Python script. This will enable deletion protection for the specified DocumentDB cluster.
