Docker Compose + GitHub Actions + Layers Cache

Decrease build time of docker compose inside GitHub Actions using layers cache.

2x faster builds:

Description

• .github/workflows/not-cached.yml uses ./docker-compose.ci.not-cached.yml. Push to ghcr.io using the :not-cached tag to avoid collisions
• .github/workflows/cached.yml uses ./docker-compose.yml. Caching achieved by:
  • ENV variables DOCKER_BUILDKIT and COMPOSE_DOCKER_CLI_BUILD
  • docker/setup-buildx-action
  • --build-arg BUILDKIT_INLINE_CACHE=1
  • cache_from inside docker-compose file:

    build:
      context: ./app1
      cache_from:
      - ghcr.io/cyanofresh/docker-compose-ga-cache-example_app1
