我正在尝试通过 nodeport 服务启用仪表板。我有 3 个虚拟机：

  • 192.168.100.31 - 主
  • 192.168.100.32 - 小黄人
  • 192.168.100.33 - 小黄人（此处为仪表板）

申请后：

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

仪表板可以通过 kube-proxy 访问。所以我把服务变成了NodePort：

kubectl edit services kubernetes-dashboard -n kube-system

然后我尝试通过 https NodePort 访问仪表板。它失败了。当我尝试访问 192.168.100.31 或 192.168.100.32 时，例如：

https://192.168.100.31:32443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/overview?namespace=default

浏览器挂起并触发超时错误。同时 192.168.100.33 的相同 URL 允许我将站点添加到浏览器异常原因导致自签名证书和...失败。

看起来您在通过 NodePort 服务直接apiserver访问服务时使用了一种请求。dashboard

您能否在浏览器中查看以下链接以访问 Kubernetes 仪表板：

https://192.168.100.31:32433/

https://192.168.100.32:32433/

https://192.168.100.33:32433/

你的 pod 类型是“ NodePort ”。美好的！。

找到你的节点 ip（主 ip）

例如类型：

ip a

和 ...

curl -k http://<Node IP>:32443

好好享受！
