通过docker安装Gitlab

水莹儿

初始化操作

• 说在前面
  Gitlab安装需要部署很多依赖和其他服务来协作，很麻烦。
  所以懒人想懒招，所以直接用Docker来部署，简单，省事，TNND还不用担心断电重启的问题！
  

操作系统

• 内核版本信息
  $ uname -a
  
• 输出如下
  Linux yang-PowerEdge-R730 4.4.0-116-generic #140-Ubuntu SMP Mon Feb 12 21:23:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
  

安装Docker

• 　　此处使用的是阿里源
  
  
• 　　step 1: 安装必要的一些系统工具
  
  $ apt-get update
  $ apt-get -y install apt-transport-https ca-certificates curl software-properties-common
  
• 　　step 2: 安装GPG证书
  
  $ curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
  
• 　　Step 3: 写入软件源信息
  
  $ add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
  
• 　　Step 4: 更新并安装 Docker-CE
  
  $ apt-get -y update
  $ apt-get -y install docker-ce
  
• 　　安装好之后，来看看Docker的版本。
  
  $   docker version
  
• 　　输出如下
  
  Client:
  Version:      17.03.2-ce
  API version:  1.27
  Go version:   go1.7.5
  Git commit:   f5ec1e2
  Built:        Tue Jun 27 03:35:14 2017
  OS/Arch:      linux/amd64
  Server:
  Version:      17.03.2-ce
  API version:  1.27 (minimum version 1.12)
  Go version:   go1.7.5
  Git commit:   f5ec1e2
  Built:        Tue Jun 27 03:35:14 2017
  OS/Arch:      linux/amd64
  Experimental: false
  　　这样Docker就安装成功了。
  
  

  　　当然路走多了也会踩到坑的！下面是我碰到的一个小坑
  
  

  
  
• 　　异常处理
  
  # 出现如下报错提示：
  Depends: libseccomp2 (>= 2.3.0) but 2.2.3-3ubuntu3 is to be installed
  Recommends: aufs-tools but it is not going to be installed
  
• 解决方法
  # 安装指定版本的docker-ce
  $  apt-cache madison docker-ce

  # 获取<17.03.0~ce-0~ubuntu-xenia>版本
  $ apt install docker-ce=17.03.2~ce-0~ubuntu-xenial
  

安装Gitlab-ce

拉取Gitlab-ce镜像

• 　　拉取最近Gitlab-ce镜像
  
  $ docker pull gitlab-ce
  # 镜像很大，1.46 GB
  
• 从本地导入
  $ docker load < gitlab-ce_docker_images.tar.gz
  # 我自己的镜像备份gitlab-ce_docker_images.tar.gz
  

创建容器

• 
  $ docker run -d \
  --hostname 10.10.1.70 \                                       # 指定容器域名,未知功能:创建镜像仓库的时候使用到
  -p 8443:443 \                                                 # 将容器内443端口映射到主机8443,提供https服务
  -p 8080:80 \                                                  # 将容器内80端口映射到主机8080,提供http服务
  -p 2222:22 \                                                  # 将容器内22端口映射到主机2222,提供ssh服务
  -p 9090:9090 \                                                # 将容器内9090端口映射到主机9090,提供prometheus服务
  --name gitlab \                                               # 指定容器名称
  --restart always \                                            # 容器退出时,自动重启
  -v /home/gitlab/config:/etc/gitlab \                          # 将本地/home/gitlab/config挂载到容器内/etc/gitlab
  -v /home/gitlab/logs:/var/log/gitlab \                         # 将本地/home/gitlab/logs挂载到容器内/var/log/gitlab
  -v /home/gitlab/data:/var/opt/gitlab \                        # 将本地/home/gitlab/data挂载到容器内/var/opt/gitlab
  gitlab/gitlab-ce:latest                                       # 镜像名称:版本
  

  　　此处我单独给/home/gitlab目录mount了一个独立硬盘，强烈建议Gitlab目录和系统盘使用不同的物理硬盘。
  
  

  
  
• 查看Gitlab容器运行情况
  $ docker inspect gitlab --format "{{.State.Status}}"
  　　输出结果如下就好
  
  running
  

配置Gitlab

配置重载

docker exec -t gitlab gitlab-ctl reconfigure
docker exec -t gitlab gitlab-ctl restart
结束

　　配置到处为止
内网使用，暂时不开启HTTPS
自签证书实现Gitlab HTTPS双向认证部分等有空了再说吧

日常管理

• 　　配置重载
  
  docker exec -t gitlab gitlab-ctl reconfigure
  docker exec -t gitlab gitlab-ctl restart
  
• 备份恢复
  # 备份
  docker exec -t gitlab gitlab-rake gitlab:backup:create
  # gitlab还原
  docker exec -t gitlab gitlab-ctl stop unicorn
  docker exec -t gitlab gitlab-ctl stop sidekiq
  docker exec -t gitlab gitlab-rake gitlab:backup:restore BACKUP=1521789664_2018_03_23_10.5.6
  docker exec -t gitlab gitlab-ctl restart
  docker exec -t gitlab gitlab-rake gitlab:check SANITIZE=true
