6.7Docker in CI/CD

Most CI platforms support Docker natively. GitHub Actions uses the services keyword to run Docker containers alongside your tests:

services:
  postgres:
    image: postgres:16
    env:
      POSTGRES_PASSWORD: testpass
    ports:
      - 5432:5432
    options: >-
      --health-cmd pg_isready
      --health-interval 10s
      --health-timeout 5s
      --health-retries 5

This is equivalent to running docker run with the same parameters, but managed by the CI platform.
