jenkins pipeline 配置

最近在向pipeline转变, 感觉部署shell控制灵活.,

1.首先jenkins 安装 Zentimestamp 插件后, 该插件允许自定义Jenkins      BUILD_TIMESTAMP变量的日期和时间模式。 docker build中使用时间戳做tag

2. 安装 Timestamper 插件, 将时间戳添加到控制台输出

3. 可以把变量提出来使用 参数化构建过程----字符参数

4.  打开部署机api端口,实现远程调用  -H=unix:///var/run/docker.sock -H=tcp://0.0.0.0:6066  注意安全问题.
