建立CD环境

1.确认cmdb_server容器有ssh服务，没有则yum install openssh-server
2.然后进入jenkins_server容器发公钥到cmdb_server
3.jenkins安装Publish over SSH，将jenkins_server的私钥填入

image

如果测试不成功，尝试以下操作：
解决办法源于此文档

Publish over SSH 这个插件为旧版本，我们下载的新的openssh-server生成秘钥为新的算法，所以如果要制作“较旧的” OpenSSH格式，请尝试此操作。
或通过使用旧的ssh-keygen进行设置

ssh-keygen -t rsa -b 4096 -m PEM

开始构建任务

image

主动执行任务后，可在cmdb_server容器中得到一个这样的文件

ls /app/code/
code.tar

基于以上操作

我们可以实现代码的简单更新，也有点类似于发布

我们在本机上写好新功能，提交到gitlab上，jenkins使用webhook拉取到代码，并且通过ssh推送到生产服务器上，生产服务器停服务，备份源代码，拉取新代码，起服务，跑新代码，有问题则回滚，一系列操作自动执行

image

bak.sh（可放到工作区下被一起打包过去）

#!/bin/bash
tar -xf /app/code/code.tar  -C /app/code/     #解压tar包
cp -r /opt/auto_cmdb /backup/auto_cmdb-$(date +%F-%X)  #备份原来的代码
rm -rf /opt/auto_cmdb    #删除原来的代码
mv /app/code/auto_cmdb /opt/    #部署新的代码

由于我们起的容器的缘故，cmdb的Dockerfile 写入了 CMD uwsgi --ini /opt/auto_cmdb/conf/uwsgi.ini

image

造成无法停止服务,虽然不合生产环境，但是不影响我们运行新的代码
当我们在访问页面时，刷新即可看到相应的改变
