- central:中央仓库,是由Maven社区提供的资源仓库,它包含了大量的常用程序库组件(jar包)。默认Maven的中央仓库地址为:http://repo1.maven.org/maven2/
- local:本地仓库,是存放maven环境本地的一个文件夹,此文件夹在第一次运行Maven命令时就创建了。Maven在执行构建任务时,根据依赖关系从中心仓库、或远程仓库下载依赖组件到本地仓库,然后本地仓库的内容供项目引用。
- remote:远程仓库,例如项目需要指定外部其他公司、或开源组织的jar包,这些依赖组件通用性等原因,未纳入Maven中央仓库,这个时候就要手动指定一个私有的远程仓库来拉取依赖。

- m2:这个是用作maven的本地仓库路径,使用hostpath挂载到了本地目录,当然也可以存储到某些共享存储中,目的就是让依赖包只下载一次。
- workspace-volume:这个是将jenkins的工作目录也使用hostpath挂载。
- docker-client:docker命令的挂载,用于build、push等命令
- docker-engine:docker engine的挂载,用于build、push等
