• for GitHub use the GitHub Actions (.github/workflows/build_docker_images.yaml):
  • checkout
  • setup-qemu-action
  • setup-buildx-action
  • login-action
  • build-push-action
  • https://docs.github.com/en/actions/learn-github-actions/environment-variables
  • dockerhub-description
• for GitLab use the .gitlab-ci.yml as an example, then hooks/ is not needed.
