安装

$ helm install kubernetes-dashboard . \
--namespace kube-system \
-f kubernetes-dashboard.yaml

查看

$ kubectl get svc -n kube-system
NAME                   TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                  AGE
kube-dns               ClusterIP   10.96.0.10     <none>        53/UDP,53/TCP,9153/TCP   32d
kubernetes-dashboard   ClusterIP   10.100.18.56   <none>        443/TCP                  22m

通过 NodePort 方式访问

$ kubectl edit svc kubernetes-dashboard -n kube-system
# 修改 ClusterIP 为 NodePort
spec:
  type: ClusterIP  ->  NodePort
$ kubectl get svc -n kube-system
NAME                   TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                  AGE
kube-dns               ClusterIP   10.96.0.10     <none>        53/UDP,53/TCP,9153/TCP   32d
