篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了通过docker安装Gitlab相关的知识，希望对你有一定的参考价值。

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

  • 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

详细配置说明文档请参考官方

  • 配置Gitlab
    首先,备份默认gitlab.rb

  • 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
