K8s部署静态节点
在命令行中启动节点java -jar agent.jar -jnlpUrl http://139.198.166.235:8080/computer/build%2D02/jenkins-agent.jnlp -secret 942d7e769a43f65388751ee954af20e90fa0c5f8bdb19e0584db4cc61adab8ba -workDir "/var/jenkins"
Run from agent command line, with the secret stored in a file:echo 942d7e769a43f65388751ee954af20e90fa0c5f8bdb19e0584db4cc61adab8ba > secret-file
java -jar agent.jar -jnlpUrl http://139.198.166.235:8080/computer/build%2D02/jenkins-agent.jnlp -secret @secret-file -workDir "/var/jenkins"我们不需要对agent创建service去访问它，这就是一个执行引擎，执行完了挂掉 。

同样的，这个agent pod里面是没有mvn这些构建工具的，可以使用卷的形式挂载进去。或者使用这个镜像作为基础镜像将工具打入到这个镜像里面更加方便。
