How can I use Docker Compose for my Python application?

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

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

In your docker-compose.yml, you should define the services you need, such as your Python app, a database, and any other dependencies. For example:

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

How do I build and run the containers?

You can build and run your containers using the command docker-compose up --build. This will build the images and start the services defined in your docker-compose.yml.

Can I run tests in a separate container?

Yes, you can define a separate service in your docker-compose.yml for running tests. Just create a service that uses your test framework and links to your application service.
