Pushed project into a repository in GitLab.

stages:
- test
- build
sast:
  stage: test
include:
- template: Security/SAST.gitlab-ci.yml

docker-build:
  # Use the official docker image.
  image: docker:latest
  stage: build
  services:

    - |
      if [[ "$CI_COMMIT_BRANCH" == "$CI_DEFAULT_BRANCH" ]]; then
        tag=""
        echo "Running on default branch '$CI_DEFAULT_BRANCH': tag = 'latest'"
      else
        tag=":$CI_COMMIT_REF_SLUG"
        echo "Running on branch '$CI_COMMIT_BRANCH': tag = $tag"
      fi
    - docker build -t "$CI_REGISTRY_IMAGE${tag}" .
    - docker push "$CI_REGISTRY_IMAGE${tag}"

  rules:
