Jenkins从属无法访问Jenkins主Kubernetes吊舱

Question

我有一个在部署时创建的，带有jenkins master和jenkins slave的kubernetes pods安装程序。

我的从属进程无法连接到主进程。我尝试将jenkins网址配置为使用端口的服务名称，使用端口配置服务ip地址，但是两者均无效。

我的服务如下：

jenkins1                  LoadBalancer  100.70.213.156  a1a3cd39dfe7011eaacd202be15828c0-1501075918.eu-west-1.elb.amazonaws.com  80:30416/TCP,50000:32699/TCP  1h

我在从属Pod中看到的错误是

SEVERE: Failed to connect to http://jenkins.infrastructure.svc.cluster.local:8080/tcpSlaveAgentListener/: jenkins.infrastructure.svc.cluster.local

这是我的服务配置

我的詹金斯配置看起来像这样
