在kubernetes中安装jenkins链接测试失败

安装地址是如下：

https://github.com/jenkinsci/kubernetes-plugin/tree/fc40c869edfd9e3904a9a56b0f80c5a25e988fa1/src/main/kubernetes

安装完后，登陆jenkins做kubernetes的链接测试发现如下报错：

Error testing connection https://kubernetes.default: Failure executing: GET at: https://kubernetes.default/api/v1/namespaces/default/pods. Message: Forbidden!Configured service account doesn't have access. Service account may have been revoked. pods is forbidden: User "system:serviceaccount:george:default" cannot list pods in the namespace "default".

究其原因是创建账户绑定的角色不对：

完整brac如下：

# In GKE need to get RBAC permissions first with
# kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin [--user=<user-name>|--group=<group-name>]
