Docker搭建GitLab

在虚拟机cent OS 7上安装docker

可以参考：https://www.runoob.com/docker/centos-docker-install.html

查看当前的内核版本

Docker 要求 CentOS 系统的内核版本高于 3.10 ，查看本页面的前提条件来验证你的CentOS 版本是否支持 Docker 。

通过 uname -r 命令查看你当前的内核版本

[root@cc ~]# uname -r 
3.10.0-957.el7.x86_64

安装 Docker

从 2017 年 3 月开始 docker 在原来的基础上分为两个分支版本: Docker CE 和 Docker EE。

Docker CE 即社区免费版，Docker EE 即企业版，强调安全，但需付费使用。

本文介绍 Docker CE 的安装使用。

移除旧的版本：

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine

[root@cc ~]# sudo yum remove docker \
>                   docker-client \
>                   docker-client-latest \
>                   docker-common \
>                   docker-latest \
>                   docker-latest-logrotate \
>                   docker-logrotate \
>                   docker-selinux \
>                   docker-engine-selinux \
>                   docker-engine

安装一些必要的系统工具：

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

添加软件源信息：

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

更新 yum 缓存：

sudo yum makecache fast

安装 Docker-ce：

sudo yum -y install docker-ce

启动 Docker 后台服务

sudo systemctl start docker

测试运行 hello-world

docker run hello-world

安装Gitlab

接下来我们就开始我们的重头戏，在docker中安装gitlab。

在docker中安装gitlab的方式有两种，一种是直接用官方提供的gitlab镜像gitlab/gitlab-ce,只需要这一个镜像就能使用 GitLab。这种安装方式也比较简单便捷。
具体的安装步骤可以去官网看看：https://docs.gitlab.com/ee/install/docker.html 或者网上也有很多教程：https://juejin.im/post/5a4c9ff36fb9a04507700fcc ，这里我就不多介绍了。

但是我更加推荐使用sameersbn 提供的sameersbn/gitlab，它将GitLab 分成了三个不同的镜像：数据库、日志、GitLab 服务，这样做的好处便于解耦，以及符合 Docker 的设计原理：轻量级、单一的镜像功能。在此，我们使用sameersbn/gitlab，并结合提供的 Docker Compose 文件来启动 GitLab。
我们可以参考它的github：https://github.com/sameersbn/docker-gitlab

所以本文介绍的就是通过sameersbn 提供的sameersbn/gitlab去安装gitlab。

安装docker-compose

首先执行以下命令

[root@cc ~]# docker-compose
-bash: docker-compose: 未找到命令

可以发现我们没有安装 docker-compose，所以我们可以参考官网 https://docs.docker.com/compose/install/

然后我们根据官网去安装。

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

[root@cc ~]# docker-compose --version
docker-compose version 1.24.1, build 4667896b

然后我们的docker-compose就安装完成了。

下载docker-compose.yml

下载docker-compose.yml文件下载到本机，参考https://github.com/sameersbn/docker-gitlab 中的Quick Start，我们下载这个文件。

wget https://raw.githubusercontent.com/sameersbn/docker-gitlab/master/docker-compose.yml

启动gitlab

docker-compose up

[root@cc ~]# docker-compose up
