Use Case: Passing ECS Health Checks

This Docker container is ideal for passing health checks on AWS ECS.
Since the container listens on all ports from 2 to 9999 and returns 200 OK for any HTTP request, you can configure your ECS service's health check to target any of these ports. Here's how you might configure the health check:

• Health Check Path: / (or any valid path)
• Port: Choose any port between 2 and 9999
• Protocol: HTTP
• Response Code: 200

By configuring your ECS service with these settings, the container will always return a 200 OK response, ensuring that the health check passes successfully.
