How can I use Docker Compose with Python for advanced applications?

You can use Docker Compose to define and run multi-container Docker applications. For Python, you can set up services like Flask or Django along with databases.

Can you show me an example of a Docker Compose file for a Flask app?

Sure! Here's a simple example:

version: '3'
services:
  web:
    image: flask:latest
    build: .
    ports:
      - "5000:5000"
    volumes:
      - .:/code
  db:
    image: postgres:latest
    environment:
      POSTGRES_DB: mydb
      POSTGRES_USER: user
      POSTGRES_PASSWORD: password

What if I want to add Redis to this setup?

You can add Redis as another service in your Docker Compose file like this:

  redis:
    image: redis:latest

This will allow your Flask app to communicate with Redis.

How do I run this Docker Compose setup?

You can run the setup by navigating to the directory containing your docker-compose.yml file and executing docker-compose up in your terminal.
