gitlab ci 部署应用骚操作

背景

完整的gitlab ci一般都有stage用于部署应用。

部分应用没有采用docker方式部署的话，怎么可以快速通过ci串联部署？

骚操作

简述：用ssh的方式进行ci控制和部署。

最终部署可以通过supervisor的方式进行部署，或者直接放后台。

环境介绍

变量名称	备注
TARGET_IP	部署机器的IP
TARGET_SSH_PORT	部署机器ssh的端口
TARGET_SSH_USER	部署机器ssh的用户名
var_id_rsa	部署机器TARGET_SSH_USER用户的私钥变量，需要以前将私钥存到gitlab ci的环境配置变量里面
