尝试在 Ubuntu 16.04 中安装 kubernetes 仪表板导致 x509: certificate signed by unknown authority 错误。

具有单个节点的 Kubernetes 集群运行良好，部署也在进行中。

尝试在没有任何锁定的情况下在 kubernetes-dashboard.yaml 文件中启用 apiserver-host 属性。

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml 无法连接到服务器：x509：证书由未知机构签名

有什么建议么。

kubectl 的输出 get all -n kube-system

kubectl 获取节点的输出

如果您指定如何部署集群但尝试重新生成集群证书会更好。如果你kubeadm从控制平面节点使用然后你可以运行

kubeadm alpha certs renew

有关更多信息，请查看此

根据原始帖子的更新进行编辑：

根据您更新的输出，正如您从事件中看到的那样，不知何故有很多行，例如：

User "system:node:ets-kubernetes" cannot list resource .........

这意味着，上述用户没有相关角色来对指定资源执行这些操作。

要解决此问题，您必须为此用户创建相关的角色和角色绑定。您可以从官方使用 RBAC 授权文档中获取更多信息
