How can I use Docker Compose in CircleCI?

You can use Docker Compose in CircleCI by defining your services in a docker-compose.yml file and using the CircleCI configuration to build and run your containers.

Can you show me a sample CircleCI configuration for that?

Sure! Here's a basic example:

version: 2.1

jobs:
  build:
    docker:
      - image: circleci/python:3.8
    steps:
      - checkout
      - run:
          name: Install Docker Compose
          command: sudo apt-get install docker-compose
      - run:
          name: Run Docker Compose
          command: docker-compose up

workflows:
  version: 2
  build:
    jobs:
      - build

What if I need to pass environment variables?

You can pass environment variables in your docker-compose.yml file or directly in the CircleCI config using the environment key under the docker section.

Is there a way to run tests in this setup?

Yes, you can add a testing service in your docker-compose.yml and run your tests as part of the CircleCI job steps.
