Kubernetes Dashboard

1、创建命名空间

k create ns kubernetes-dashboard
alias kd='k -n kubernetes-dashboard'

2、编辑YAML

vi kubernetes-dashboard.yaml

3、部署Pod

kubectl apply -f kubernetes-dashboard.yaml
Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
namespace/kubernetes-dashboard configured
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created

4、查看资源

kubectl get pod,svc -n kubernetes-dashboard -o wide

5、生产Token

kubectl describe -n kube-system  $(kubectl -n  kube-system get secret -n kube-system  -o name  | grep namespace) | grep token

6、Web界面访问

注意：一定是https，否则无法访问

kd get pod -o widenetstat -aptn|grep 311telnet ip地址 31111

http://ip地址:31111/
