Continuous integration

TODO: build -> version only in test

Using Git branches to build releases and trigger deployments

make latest

make release

Example: Gitlab CI

  • build
  • test
  • report
  • deploy
  • cleanup

http://docs.gitlab.com/ce/ci/yaml/README.html

GitLab CI

Example trigger for stacks-staging

deploy:latest:
  stage: deploy
  script:
    - curl -X POST -F token=${PROJECT_TOKEN} -F ref=${PROJECT_REF} -F "variables[REDEPLOY_STACK_DIR]=${STACK_DIR}"  https://git.hrzg.de/api/v3/projects/256/trigger/builds
  only:
    - latest

Variables:

  • PROJECT_TOKEN - token from stacks-staging project
  • PROJECT_REF - branch, usually master
  • PROJECT_DIR - location of docker-compose.yml, eg. auto/cusomter/www.example.com

Setup

Set Variables

  • PHP_IMAGE_NAME registry.example.com/namespace/project_php
  • GITHUB_API_TOKEN abcd1234

Workflow

  1. Clone application from local repository
  2. Start application make all
  3. Make changes in local development stack
  4. (optional) Run tests in isolated local testing stack make TEST up setup run-tests
  5. Commit (triggers CI)
  6. CI builds images
  7. CI starts isolated stacks (by setting custom COMPOSE_PROJECT_NAMEs) from built images and performs setup operations
  8. CI runs tests (also acceptance tests with Selenium containers)
  9. CI creates reports
  10. CI performs cleanup of isolated stacks
  11. CI tags images and pushes them to a registry (if tests were successful)

Run the test suites from build scripts

$ sh build/scripts/build.sh
$ sh build/scripts/test.sh

Building the :production image

Adjust your Dockerfile and build FROM phundament/app:production.

make build

Travis

Push example

after_success: |
  docker login -u="$REGISTRY_USER" -p="$REGISTRY_PASS" $REGISTRY_HOST
  if [ "${TRAVIS_BRANCH}" = "release" ]; then
    docker tag ${STACK_PHP_IMAGE} ${STACK_PHP_IMAGE_LATEST}
    docker-compose push || exit 1
    docker push ${STACK_PHP_IMAGE_LATEST} || exit 1
  fi
  docker logout

Production

  • All images MUST BE tagged

Push to branch foo results in Docker image appsrc:foo.
