说明:

• 目录jdk是jdk-8u151-linux-x64.tar.gz解压后的目录,目的是让每个slave都在镜像中就有jdk环境
• 目录maven是apache-maven-3.5.3-bin.tar.gz解压后的目录,目的是让每个slave都有mvn环境
• kubectl是二进制的kubectl文件
• jenkins-slave 是 github的jenkinsci 提供的执行文件
• slave.jar 是部署了jenkins 之后jenkins自己提供的一个jar包
  • 一般路径为：http://yourserver:port/jnlpJars/slave.jar
  • 在本文环境下的路径为: http://192.168.3.28:30001/jnlpJars/slave.jar
• config文件是k8s集群下 /root/.kube/config
