GitLab 冷知识：在 Gitlab CI Pipeline 中进行 Git Push 操作 🦊

# example
include:
  - local: '/templates/.gitlab-ci-template.yml'

# 可以导入同一项目的多个文件
include:
  - project: 'my-group/my-project'
    ref: main
    file:
      - '/templates/.builds.yml'
      - '/templates/.tests.yml'

# 可通过 HTTP/HTTPS GET 请求访问的公共 URL。不支持使用远端 URL 进行身份验证。
include:
  - remote: 'https://gitlab.com/example-project/-/raw/main/.gitlab-ci.yml'

# File sourced from the GitLab template collection
include:
  - template: Auto-DevOps.gitlab-ci.yml

# extend example
.tests:
  script: rake test
  stage: test

    refs:
      - branches

  extends: .tests
  script: rake rspec
  only:
    variables:
      - $RSPEC
