Container Lifecycle Management

A comprehensive solution for managing Docker container lifecycles using AWS services.

Features

• Automated container status tracking using CloudWatch events
• Automatic decommissioning of unused containers
• Container image cleanup
• Real-time notifications for abnormal container behavior
• Integration with Slack for alerts

Architecture

The solution uses the following AWS services:

• AWS Lambda for container management logic
• CloudWatch Events for scheduling and monitoring
• SQS for message queuing
• SNS for notifications
• AWS CDK for infrastructure as code

Prerequisites

• AWS CLI configured with appropriate credentials
• Python 3.9 or later
• Docker installed locally
• AWS CDK CLI installed

Setup

1. Install dependencies:

pip install -r requirements.txt

2. Configure AWS credentials:

aws configure

3. Deploy the infrastructure:

cdk deploy

4. Configure Slack webhook URL in AWS Systems Manager Parameter Store:

aws ssm put-parameter --name "/container-lifecycle/slack-webhook" --type "SecureString" --value "your-slack-webhook-url"

Usage

The system will automatically:

• Monitor container status every 5 minutes
• Clean up unused containers after 24 hours of inactivity
• Remove unused images
• Send notifications for:
  • Container crashes
  • High resource usage
  • Failed deployments
  • Security vulnerabilities

Monitoring

• CloudWatch Logs: Container management logs
• CloudWatch Metrics: Container health metrics
• SNS Topics: Alert notifications
• Slack Channel: Real-time alerts
