Project Solution: Running the App

Explore how to launch and manage a scalable quiz application using Docker Compose. Learn to run the app in development mode with live reloading, access containers via IP addresses, debug Node.js, and deploy in production mode with isolated services. Understand cleanup commands to remove containers, images, and volumes to maintain a clean Docker environment.

We'll cover the following...

  • The Node.js debugger at port {nodejs_container_IP}:9229.

You can find the container’s IP using: ...
