问题

使用节点的特定 IP 启动 kubectl proxy 时 http: proxy error: x509: certificate signed by unknown authority 是什么原因？

kubectl proxy --port=8001 --address=172.31.0.16 --accept-hosts='172.31.0.16'

I1222 09:00:03.471836   16775 logs.go:41] http: proxy error: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes")

【问题讨论】：

类似错误：Unable to connect to the server: x509: certificate signed by unknown authority，仅通过验证 gcloud container clusters get-credentials cluster-name --zone us-eastx-y --project my-project 即可解决。
