Kubernetes拒绝来自本地kubectl客户端的pod日志

Question

我有一个Kubernetes集群，开始在主机上使用rancher。我试图很少开始[http://docs.seldon.io/install.html]]。我能够启动豆荚，但无法从kubectl logs命令获取豆荚日志。

我得到的错误 “从服务器（错误请求）错误：服务器拒绝了我们未知原因请求（获取豆荚XXX）”

kubectl version显示以下内容：

Client Version: version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.2", GitCommit:"08e099554f3c31f6e6f07b448ab3ed78d0520507", GitTreeState:"clean", BuildDate:"2017-01-12T04:57:25Z", GoVersion:"go1.7.4", Compiler:"gc", Platform:"linux/amd64"} Server Version: version.Info{Major:"1", Minor:"5+", GitVersion:"v1.5.0-115+611cbb22703182", GitCommit:"611cbb22703182611863beda17bf9f3e90afa148", GitTreeState:"clean", BuildDate:"2017-01-13T18:03:00Z", GoVersion:"go1.7.4", Compiler:"gc", Platform:"linux/amd64"}

旧版本的Kubernetes存在问题，应该在最新版本中解决，请参阅此处详细讨论此issue。

我试着用最新的版本，它工作得很好：

$ kubectl log kubernetes-dashboard-1cvm4 --namespace kube-system 
W0412 10:47:32.040258 13000 cmd.go:361] log is DEPRECATED and will be removed in a future version. Use logs instead.

Kubernetes版本：

$ kubectl version
