foxel/dcos-gitlab-runner-service

dcos-gitlab-runner-service（分叉版）

这是一个定制化Docker镜像，用于在DC/OS平台上通过Marathon运行可扩展的GitLab CI runner。

配置说明

GitLab runner可通过环境变量配置，关键变量如下：

• GITLAB_SERVICE_NAME：GitLab实例的Mesos DNS服务名（如gitlab.marathon.mesos），与GITLAB_INSTANCE_URL二选一必填。
• GITLAB_INSTANCE_URL：GitLab实例的URL（如http://gitlab.mycompany.com），与GITLAB_SERVICE_NAME二选一必填。
• REGISTRATION_TOKEN：GitLab实例的注册令牌，必填。
• RUNNER_EXECUTOR：执行器类型（如shell或docker），必填。
• RUNNER_CONCURRENT_BUILDS：并发构建数，默认1。
• RUNNER_TAG_LIST：逗号分隔的标签列表，用于区分runner类型。

使用私有Docker registry

通过在项目设置 ➔ CI/CD 流水线中添加DOCKER_AUTH_CONFIG秘密变量，可使用私有Docker registry，详情参考官方指南。

在DC/OS上运行

该镜像使用Docker-in-Docker技术，以下是Marathon配置示例：

Shell runner（支持构建Docker镜像）

javascript
{
  "id": "gitlab-runner-shell",
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "foxel/dcos-gitlab-runner-service:latest",
      "network": "HOST",
      "forcePullImage": true,
      "privileged": true
    }
  },
  "instances": 1,
  "cpus": 1,
  "mem": 2048,
  "env": {
    "GITLAB_SERVICE_NAME": "gitlab.marathon.mesos",
    "REGISTRATION_TOKEN": "zzNWmRE--SBfeMfiKCMh",
    "RUNNER_EXECUTOR": "shell",
    "RUNNER_TAG_LIST": "shell,build-as-docker",
    "RUNNER_CONCURRENT_BUILDS": "4"
  },
  "taskKillGracePeriodSeconds": 15,
  "healthChecks": [
     {
       "path": "/metrics",
       "portIndex": 0,
       "protocol": "HTTP",
       "gracePeriodSeconds": 300,
       "intervalSeconds": 60,
       "timeoutSeconds": 20,
       "maxConsecutiveFailures": 3,
       "ignoreHttp1xx": false
     }
  ]
}

Docker runner（支持容器内构建）

javascript
{
  "id": "gitlab-runner-docker",
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "foxel/dcos-gitlab-runner-service:latest",
      "network": "HOST",
      "forcePullImage": true,
      "privileged": true
    }
  },
  "instances": 1,
  "cpus": 1,
  "mem": 2048,
  "env": {
    "GITLAB_SERVICE_NAME": "gitlab.marathon.mesos",
    "REGISTRATION_TOKEN": "zzNWmRE--SBfeMfiKCMh",
    "RUNNER_EXECUTOR": "docker",
    "RUNNER_TAG_LIST": "docker,build-in-docker",
    "RUNNER_CONCURRENT_BUILDS": "4",
    "DOCKER_IMAGE": "node:6-wheezy"
  },
  "taskKillGracePeriodSeconds": 15,
  "healthChecks": [
     {
        "path": "/metrics",
        "portIndex": 0,
        "protocol": "HTTP",
        "gracePeriodSeconds": 300,
        "intervalSeconds": 60,
        "timeoutSeconds": 20,
        "maxConsecutiveFailures": 3,
        "ignoreHttp1xx": false
      }
  ]
}

在GitLab CI中使用

构建Docker镜像（shell runner）

yaml
stages:
  - ci

build-job:
  stage: ci
  tags:
    - build-as-docker
  script:
    - docker build -t tobilg/test .

容器内构建（docker runner）

yaml
image: node:6-wheezy

stages:
  - ci

test-job:
  stage: ci
  tags:
    - build-in-docker
  script:
    - node --version
