rpm，docker,k8s三种方式安装部署GitLab服务

rpm方式

源地址：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-12.9.0-ce.0.el7.x86_64.rpm

rpm -ivh gitlab-ce-12.9.0-ce.0.el7.x86_64.rpm

vim /etc/gitlab.rb   # 编辑站点地址
gitlab-ctl reconfigure  # 配置

#服务控制
gitlab-ctl start
gitlab-ctl status
gitlab-ctl stop

Docker方式

mkdir -p ~/data/gitlab/config ~/data/gitlab/logs ~/data/gitlab/data
docker pull gitlab/gitlab-ce:12.9.0-ce.0

docker run -d  -p 443:443 -p 80:80 -p 222:22 --name gitlab --restart always -v /Users/zeyang/data/gitlab/config:/etc/gitlab -v /Users/zeyang/data/gitlab/logs:/var/log/gitlab -v /Users/zeyang/data/gitlab/data:/var/opt/gitlab gitlab/gitlab-ce:12.9.0-ce.0

docker exec -it gitlab   bash
vim /etc/gitlab.rb   # 编辑站点地址
gitlab-ctl reconfigure  # 配置

docker restart gitlab

#服务控制
docker start gitlab
docker stop gitlab
docker rm gitlab

注意： 需要修改gitlab.rb配置文件中的站点地址。这里指定的端口是30088（不是必须的）也就是需要将gitlab.rb配置的地址改成30088和nodePort端口为30088。

为什么端口要改成一致的？如果不修改gitlab.rb中的站点地址则默认是80端口，这时候做nodePort的时候例如将80映射到30088，此时对外访问30088可以打开gitlab页面，但是下载代码的时候会发现地址为80端口，导致下载代码失败。所以这里强调一致哦。
