gitlab-ci.yml

提示

使用 extends 复用现有逻辑
使用 !reference [.setup, before_script] 复用部分逻辑 - 例如合并多个 before_script
可以使用 YAML 引用逻辑

job:only/except

警告

开发不活跃，推荐，使用 rules

build:
  script: npm run build
  only:
    # 简单配置 - refs
    # 完整匹配 - master 分支运行
    - master
    # 支持正则 匹配 tag 或 branch - 如果 排除了 branches 则是匹配 tag
    - /^issue-.*$/i

    # 高级配置
    # 不指定默认则是 refs 匹配
    refs:
      - master
      - schedules
    # 变量匹配
    variables:
      - $CI_COMMIT_MESSAGE =~ /run-end-to-end-tests/ # 匹配变量
      - $RELEASE == "staging" # 变量满足
      - $STAGING # 有变量
      # 复杂条件变量
      - ($CI_COMMIT_BRANCH == "master" || $CI_COMMIT_BRANCH == "develop") && $MY_VARIABLE
    # 匹配变化文件
    # 只有在 branches external_pull_requests merge_requests 有效
    changes:
      - README.md
      - "*.md" # 例如 从新生成文档
      - base/Dockerfile # 例如 重构基础镜像
      - "**/*.sql" # 例如 数据库迁移
    # 要求开启了 k8s 服务
    kubernetes: active
  except:
    # 支持使用关键词 - 分支不触发
    - branches
    # 可包含仓库信息匹配 - 用于 fork 场景
    - /^release/.*$/@gitlab-org/gitlab
