代理后面的库贝克特尔

Question

我已经按照这里的说明使用 minikube 安装了一个本地 Kubernetes 集群。

我在公司代理下。因此，我设置了http_proxy和https_proxy环境变量。在minikube start命令后启动集群后，我还minikube ip的值添加到no_proxy env var 中。但是，kubectl 仍然无法连接到集群。

ubuntu@ros-2:~$ kubectl -v=7 get pods

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 不知道no_proxy设置。对集群的简单卷曲就可以了。

关于如何解决这个问题的任何想法？

Answer 1

修复了此问题。解决方法是将no_proxy详细信息也放在NO_PROXY中。

export NO_PROXY=$no_proxy,$(minikube ip)
