How can I set up an advanced Express.js application using Docker Compose?

To set up an advanced Express.js application with Docker Compose, you'll need to create a Dockerfile for your app and a docker-compose.yml file to define your services.

What should I include in my Dockerfile?

Your Dockerfile should include the base image, install dependencies, copy your application code, and specify the command to run your app.

Can you give me an example of a docker-compose.yml file?

Sure! Here's a basic example:

version: '3'
services:
  web:
    build: .
    ports:
      - '3000:3000'
    volumes:
      - .:/app
    environment:
      - NODE_ENV=production

How do I run my application after setting it up?

You can run your application by executing docker-compose up in your terminal. This will start all defined services.
