1、配置启动脚本

version: '3.1'
services:
  gitlab-ce:
    image: 'gitlab/gitlab-ce:latest'
    container_name: gitlab-ce
    restart: always
    hostname: 'gitlab.localhost.com'
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'http://192.168.31.109'
# external_url是项目生成时的前缀域名
    ports:
      - '80:80'
      - '443:443'
      - '10022:22'
    volumes:
      - '/root/gitlab-ce/home/config:/etc/gitlab'
      - '/root/gitlab-ce/home/logs:/var/log/gitlab'
      - '/root/gitlab-ce/home/data:/var/opt/gitlab'
    networks:
      - 'default'

  gitlab-runner:
    image: 'gitlab/gitlab-runner:latest'
    container_name: gitlab-runner
    depends_on:
      - 'gitlab-ce'
    restart: always
    volumes:
      - '/root/gitlab-ce/runnerconfig:/etc/gitlab-runner'
      - '/var/run/docker.sock:/var/run/docker.sock'
    networks:
      - 'default'
    links:
      - 'gitlab-ce:gitlab.localhost.com'

networks:
  default:
    driver: 'bridge'

两个容器使用gitlab.localhost.com一个域名，以便在注册runner时可以访问网络

2、注册runner

docker-compose exec gitlab-runner /bin/bash # 连接进入 gitlab-runner 容器

gitlab-runner register               # 进入容器后执行的命令                            
                                                   
Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
http://gitlab.localhost.com                   # gitlab 的访问路径
Please enter the gitlab-ci token for this runner:
JLP2Rk2qcUZEfs_WLrTv                   # 注册令牌，在 gitlab 中获取
Please enter the gitlab-ci description for this runner:
[gitlab-runner]: test_runner           # runner 的名字
Please enter the gitlab-ci tags for this runner (comma separated):
test                                   # runner 的 tag
Registering runner... succeeded                     runner=JLP2Rk2q
Please enter the executor: docker-ssh, parallels, docker+machine, docker-ssh+machine, docker, shell, ssh, virtualbox, kubernetes:
docker                                 # 使用 docker 作为输出模式
Please enter the default Docker image (e.g. ruby:2.1):
alpine:latest                          # 使用的基础镜像
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!
#############################    注册成功后会显示以上信息，然后执行下面的命令进行启动  ###################################

gitlab-runner start                    # 启动该 runner

3、检查runner状态
