How do I use Docker Compose with CircleCI?

To use Docker Compose with CircleCI, you need to define your services in a docker-compose.yml file and then configure your CircleCI config to use Docker.

Can you show me a sample CircleCI config file?

Sure! Here's a basic example:

version: 2.1
jobs:
  build:
    docker:
      - image: circleci/python:3.8
    steps:
      - checkout
      - run:
          name: Install dependencies
          command: |
            docker-compose up -d
            docker-compose exec app pip install -r requirements.txt

What if I need to run tests in my Docker container?

You can add a step in your CircleCI config to run tests after your services are up. For example:

      - run:
          name: Run tests
          command: docker-compose exec app pytest
