我在 AWS 上的 EC2 实例上安装了一个 kubernetes 集群。

1 个主节点和 2 个工作节点。

当我连接到主节点并使用kubectl.

但我希望能够kubectl从我的本地机器发出命令。所以我将.kube/config文件的内容从主节点复制到本地机器的.kube/config.

我只更改了服务器的 ip 地址,因为原始文件引用了内部 ip。该文件现在看起来像这样:

当我尝试使用kubectl本地计算机上的命令时,出现此错误:

Unable to connect to the server: x509: certificate is valid for 10.96.0.1, 172.31.4.108, not 35.166.48.257

这是 bcs kube-api 服务器 TLS证书仅对10.96.0.1, 172.31.4.108. 35.166.48.257有几个选项,比如告诉kubectl跳过 TLS 验证,但我不会重新推荐。最好的办法是在集群上重新生成整个 PKI。

两种方式都在这里描述

下次对于 kubeadm 集群,您可以--apiserver-cert-extra-sans=EXTERNAL_IP在集群初始化时使用,还将外部 IP 添加到 API Server TLS 证书。
