使用Docker或者docker-compose搭建gitlab

一. 直接下载docker-ce

1. 拉取gitlab/gitlab-ce

Randy:~ Randy$ docker pull gitlab/gitlab-ce
Using default tag: latest

2. 运行gitlab/gitlab-ce

Randy:~ Randy$ docker run -d --publish 8443:443 --publish 8001:80 --publish 8022:22 --name gitlab-randy --restart always gitlab/gitlab-ce

其中使用publish参数映射host主机上的8443到docker-ce上面的443端口，并制定使用bash。此处可以使用–volume参数来指定docker-ce中的文件到host主机上的路径以便于升级，此处仅作为测试使用。

3. 验证http://127.0.0.1:8001/可以登录，首次登录需要修改密码

二. 使用Docker-compose方式

这种方式是比较灵活，也是官方推荐的安装方式。实际上就是把启动docker的参数配置到文件中，并通过docker-compose up调用。步骤如下：

1. 下载docker-compose.yml文件

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

[root@randysun ~]# wget https://raw.githubusercontent.com/sameersbn/docker-gitlab/master/docker-compose.yml

2. 在第一步中下载好的文件路径下运行docker-compose up

[root@randysun ~]# docker-compose up
