matrix:
  include:
    - REPO_URL: "git.yimengapp.com"
      LOCAL_VOLUME: "/var/www/yimeng"
pipeline:
  clone:
    image: plugins/git
    volumes:
      - ${LOCAL_VOLUME}/master:/drone/src/${REPO_URL}/${DRONE_REPO}
    when:
      branch: master

  clone:
    image: plugins/git
    volumes:
      - ${LOCAL_VOLUME}/release:/drone/src/${REPO_URL}/${DRONE_REPO}
    when:
      branch: release

  clone:
    image: plugins/git
    volumes:
      - ${LOCAL_VOLUME}/develop:/drone/src/${REPO_URL}/${DRONE_REPO}
    when:
      branch: [ dev, develop ]

  busybox:
    image: busybox
    volumes:
      - ${LOCAL_VOLUME}/:${LOCAL_VOLUME}
    commands:
      - if [ ${DRONE_BRANCH} == master ]; then chown -R 33:33 ${LOCAL_VOLUME}/master ; fi
      - if [ ${DRONE_BRANCH} == release ]; then chown -R 33:33 ${LOCAL_VOLUME}/release ; fi
      - if [ ${DRONE_BRANCH} == develop ]; then chown -R 33:33 ${LOCAL_VOLUME}/develop ; fi

volumes:必须加 否则依然挂载主机工作目录默认为 /drone，
workspace:
base: /go # 绝对路径 默认为 /drone
path: src/github.com/octocat/hello-world #相对路径 配合base拼接出项目下载的绝对地址
因为 workspace为docker创建的目录，所以必须手动挂载volume去覆盖内部的，才能做到目录共享
工作原理:

  1. drone 根据workspace在docker中创建volume 工作目录，其他stage共享此volume 结束后销毁
  2. 在clone 阶段 手工指定volumes 覆盖 系统创建的工作目录
  3. 因为其他stage共享系统创建的volume 因此手工指定的volumes并不共享，因此如果想要使用的话依然需要显示volumes：

clone 阶段是pipeline 第一个阶段

跳过clone

跳过clone 有两种解决方案：

  1. 全局跳过 这种方式解决的比较彻底，但还是会带来一次构建

    pipeline:
clone:
image: busybox
commands: ls /
volumes: /tmp:/tmp

  2. 将你需要执行的stage 添加到clone：下即可，但是如果添加条件支持的话 需要添加多个step clone:标签
    注意: step标签名必须为clone:

    pipeline:
clone:
image: plugins/ssh
host: [ qubuluo.com ]
user: root
port: 22
script:
  - echo master >master.txt
  - echo master
when:
  branch: master
clone:
image: plugins/ssh
host: [ qubuluo.com ]
user: root
port: 22
script:
  - echo dev >dev.txt
  - echo dev
when:
  branch: dev

为clone 增加缓存

  1. 开启Trusted # drone exec --repo.trusted

  2. 创建自定义Dockerfile 镜像

    FROM plugins/git
VOLUME /drone
# docker build -t rinetd/drone-git && docker push rinetd/drone-git

  3. 创建自定义 clone stage
    volumes：/drone:/drone

    pipeline:
clone:
image: rinetd/drone-git
volumes: /drone:/drone

  4. drone agent 以 root 权限运行 否则没有文件写入权限
    或者 /drone 目录必须权限必须更改为agent运行用户

Drone automatically prepends a clone step to your Yaml file if one does not already exist. You can manually configure the clone step in your pipeline for customization:

pipeline:

  • clone:
  • image: plugins/git

Example configuration to override depth:

pipeline:
clone:

image: plugins/git
  • depth: 50

Example configuration to use a custom clone plugin:

pipeline:
clone:

  • image: octocat/custom-git-plugin
