1，基本概念
- 使用k8s安装gitlab-ce，采用GlusterFS实现持久化(注意PG使用的是NFS存储，使用动态存储重启postgresql的pod后无法成功启动pg，待解决)，并集成了openLDAP。
- 注意：使用的gitlab是独立于k8s集群之外的。
2，安装部署
2.1 下载yaml文件
git clone https://github.com/xiaoqshuo/k8s-cluster.git
2.2 修改对应的配置
- 主要修改每个rc的namespace，使用的持久化存储方式(当前yaml使用的GFS动态存储，pg使用的是NFS，按需修改)
- 修改gitlab-rc.yml里面的env，对应的LDAP信息和SMTP信息等
- 修改traefik的域名
- 创建gitlab

3，配置 GitLab
3.1 登录
3.2 ldap 登录
4，创建项目
4.1 首先创建一个群组
4.2 创建项目
4.3 添加用户权限
4.4 添加SSH Key
- 如果没有Key需要使用ssh-keygen -t rsa -C "your@email.com"生成对应的Key。
4.5 拉取项目
4.5.1 README
4.5.2 创建分支
4.5.3 拉代码
- 克隆代码，注意此时需要更改git的地址，因为ssh端口并非22，可以通过service查看nodeport的端口
