Remove deployment ID on ec2

1. Automate Cleanup with a Script:

You can create a script to automatically delete old deployment directories while keeping a certain number of the most recent ones.

Here's a basic example in Bash that you could run as a cron job on your EC2 instances:

#!/bin/bash

DEPLOYMENT_ROOT="/opt/codedeploy-agent/deployment-root"
MAX_DEPLOYMENTS=5

for group in "$DEPLOYMENT_ROOT"/*/; do
    cd "$group" || continue
    deployments=($(ls -d */ | sort -r))
    
    if [ ${#deployments[@]} -gt $MAX_DEPLOYMENTS ]; then
        echo "Cleaning up old deployments in $group"
        to_delete=("${deployments[@]:$MAX_DEPLOYMENTS}")
        
        for deployment in "${to_delete[@]}"; do
            rm -rf "$deployment"
            echo "Deleted: $deployment"
        done
    fi
done

This script:

Lists all deployment directories in reverse order (newest first).

Keeps the latest $MAX_DEPLOYMENTS and deletes the rest.

Setup as a Cron Job: To run this script regularly, you can set it up as a cron job on your instances.

crontab -e

Add a line like this to run the script daily at midnight:

0 0 * * * /path/to/cleanup-script.sh

2. Use a CloudWatch Agent:

You can use the CloudWatch agent to monitor disk space and trigger an automated cleanup process when disk usage exceeds a certain threshold. This involves setting up a CloudWatch Alarm that triggers a Lambda function or an SSM Automation document to clean up old deployments.

3. Lambda Function for Cleanup (If the Instances Are Managed via Systems Manager):

If your instances are managed via AWS Systems Manager (SSM), you can create a Lambda function that periodically connects to your instances and performs the cleanup.

Here's an outline of the approach:

Create an SSM document that runs the cleanup script on your instances.

Schedule the document to run periodically via EventBridge (formerly CloudWatch Events)

4. Using AWS Systems Manager Maintenance Windows:

You can set up an AWS Systems Manager Maintenance Window that runs a cleanup command (similar to the script above) on a regular schedule. This method provides better control over when the cleanup occurs and ensures it only runs during specified times.
