利用docker compose启动gitlab及runner

Posted 2020-08-26 Supper阿欣

添加docker compose配置文件

新建文件docker-compose.yml，输入如下内容：

gitlab:
  image: \'gitlab/gitlab-ce:latest\'
  container_name: \'gitlab\'
  restart: always
  hostname: \'gitlab.cjx.com\'
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      external_url \'http://gitlab.cjx.com\'
      # Add any other gitlab.rb configuration here, each on its own line
  ports:
    - \'80:80\'
    - \'443:443\'
    - \'60000:22\'
  volumes:
    - \'/srv/gitlab/config:/etc/gitlab\'
    - \'/srv/gitlab/logs:/var/log/gitlab\'
    - \'/srv/gitlab/data:/var/opt/gitlab\'
runner:
  image: \'gitlab/gitlab-runner:latest\'
  container_name: \'gitlab-runner\'
  restart: always
  links:
    - gitlab:gitlab.cjx.com
  volumes:
    - \'/srv/gitlab-runner/config:/etc/gitlab-runner\'
    - \'/var/run/docker.sock:/var/run/docker.sock\'

利用docker compose启动容器

docker-compose up -d

注册Runner，配置CI脚本

修正使用Docker方式执行时，无法正确link到gitlab的问题

虽然在gitlab-runner这个容器里面，有link到gitlab，但是build如果是选择的docker，执行时会再启动一个子容器，子容器无法识别自定义host：gitlab.cjx.com，会报 port 80 : connection refused错误，解决办法是在runnner的配置文件添加links参数

sudo vi /srv/gitlab-runner/config/config.toml

在[runners.docker]节点下面，添加红色字部分

 executor = "docker"
  [runners.docker]
    links = ["gitlab:gitlab.cjx.com"]
    tls_verify = false
    image = "ruby:2.1"
    privileged = false
    disable_cache = false
    volumes = ["/cache"]

添加好之后，重启runner，就可以正常访问到gitlab获取code了。 

docker exec -it gitlab-runner gitlab-runner restart
