本文主要是介绍kubernetes 之dashboard，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

将部署配置文件kubernetes-dashboard这个service修改为NodePort类型，这里没有，直接添加
kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  ports:
    - port: 443
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
  type: NodePort

Warning: resource secrets/kubernetes-dashboard-key-holder is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply. kubectl apply should only be used on resources created declaratively by either kubectl create --save-config or kubectl apply. The missing annotation will be patched automatically.

由上可知，访问地址是：https://10.0.0.6:30766/ 或者是.4 .5的ip也行

mcwk8s-node2 10.0.0.6

页面访问

需要使用token，如果没有创建账号和secret的话，

可以创建账号，这里其实部署的时候已经创建好了
