错误“由未知授权机构签名的证书"；切换GCP项目后 [英] Error "certificate signed by unknown authority" after switching GCP project

问题描述

使用...切换gcloud项目后

After switching gcloud projects using ...

gcloud init

...然后尝试执行一些kubectl命令，例如:

... and then try to do some kubectl command, like this for instance:

kubectl get rc

...我收到此错误:

... I get this error:

error: couldn't read version from server: Get
https://130.211.59.254/api: x509: certificate signed by unknown authority

这是为什么，我该如何解决?

Why is this and how can I solve it?

推荐答案

这是因为缓存了旧群集的密钥.我不确定为什么gcloud init命令不会更新它们(这是人们的直觉期望，或者至少是来自kubectl的一些更错误的消息)

This is because the keys to your old cluster is cached. I'm not sure why they are not updated by the gcloud init command (that's what one would intuitively expect, or at least some kinder error message from kubectl)

您只需在新配置中获取集群的凭据即可解决该问题:

You solve it by simply getting the credentials of the cluster in the new configuration:

gcloud container clusters get-credentials YOURCLUSTERHERE --zone YOURCLUSTERZONEHERE
