使用 docker 安装 gitlab 并且配置 runner 服务

一、修改 docker 镜像源为国内源

# vi /etc/docker/daemon.json

{
  "registry-mirrors": ["https://lvpmz2sk.mirror.aliyuncs.com"]
}
systemctl reload docker #修改完成后重新载入docker服务

二、使用 docker-compose 管理 gitlab 和 gitlab-runner 容器镜像

# vi docker-compose.yml
version: '2' 
services:
    gitlab:
        image: gitlab/gitlab-ce:11.0.0-ce.0
        restart: always
        hostname: gitlab
        container_name: gitlab
        ports:
            - 80:80
        volumes:
            - /etc/localtime:/etc/localtime
            - ./conf:/etc/gitlab
            - ./data/logs:/var/log/gitlab
            - ./data/data:/var/opt/gitlab
    gitlab-runner:                                                                                                                                           
        image: gitlab/gitlab-runner
        restart: always
        hostname: gitlab-runner
        container_name: gitlab-runner
        extra_hosts:
            - git.imlcs.top:192.168.88.167
        depends_on:
            - gitlab
        volumes:
            - /etc/localtime:/etc/localtime
            - ./runner:/etc/gitlab-runner

目录结构

安装过程中遇到的问题：

/opt/gitlab/embedded/bin/runsvdir-start: line 24: ulimit: pending signals: cannot modify limit: Operation not permitted 
/opt/gitlab/embedded/bin/runsvdir-start: line 37: /proc/sys/fs/file-max: Read-only file system Configuring GitLab package... Configuring GitLab... 

解决方法：

chmod 2770 data/data/git-data/repositories
docker-compose down
docker-compose up -d（初次创建时 gitlab 启动很慢，估计需要十几分钟左右）

三、gitlab 成功启动后连接到 gitlab-runner 配置 gitlab 的 gitlab-runner

docker-compose exec gitlab-runner sh # 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://git.imlcs.top                   # 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

使用 root 用户登录 gitlab 后获取令牌
