How can I use Docker Compose for my Python applications?

You can use Docker Compose to define and run multi-container Docker applications. For Python apps, you typically create a docker-compose.yml file that specifies the services, networks, and volumes needed.

What should I include in the docker-compose.yml file?

In your docker-compose.yml, you should define the services, such as your Python app, and specify the image, build context, ports, and any environment variables.

Can you give me an example of a simple docker-compose.yml for a Flask app?

Sure! Here's a simple example:

version: '3'
services:
  web:
    image: flask-app
    build: .
    ports:
      - "5000:5000"
    environment:
      - FLASK_ENV=development

How do I run the Docker Compose setup?

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