代理服务器后面的kubectl

Question

我已经按照说明here使用minikube安装了一个本地Kubernetes服务器群集。

我属于公司代理机构。因此我设置了http_proxy和https_proxy env变量。一旦群集在minikube start命令之后启动，我还将值minikube ip添加到no_proxy env var。但是kubectl仍然无法连接到群集。

ubuntu@ros-2:~$ kubectl -v=7 get pods 
I0105 10:31:47.773801 17607 loader.go:354] Config loaded from file /home/ubuntu/.kube/config

F0105 10:31:47.783181 17607 helpers.go:116] Unable to connect to the server: Forbidden port 

我假设这是因为kubectl没有意识到no_proxy设置。一个简单的卷曲到集群过得很好。

有关如何解决此问题的任何想法？

Answer 1

修复了这个问题。解决方法是在NO_PROXY中也有no_proxy细节。

export NO_PROXY=$no_proxy,$(minikube ip)
