如何通过节点启用kubernetes仪表板？

Question

我正在尝试通过nodeport服务启用仪表板。我有三个越南船民：

• 192.168.100.31 -硕士
• 192.168.100.32 -仆从
• 192.168.100.33 -仆从(这里的仪表盘)

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代理访问。因此，我已将服务更改为NodePort：

kubectl edit services kubernetes-dashboard -n kube-system

然后，我尝试通过https NodePort访问仪表板。结果失败了。当我试图访问192.168.100.31或192.168.100.32时：

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

浏览器挂起&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自签名证书和.失败。

Answer 1

看起来，在通过apiserver服务直接访问dashboard服务时，您正在使用NodePort类型的请求。

请检查浏览器中的下列链接以访问Kubernetes仪表板：

https://192.168.100.31:32433/

https://192.168.100.32:32433/

https://192.168.100.33:32433/

Answer 2

你的豆荚类型是"NodePort“。好吧！。

查找您的节点ip (主ip)

例如，类型：

ip a

还有..。

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

好好享受吧！
