OS: Ubuntu Server 22.04 LTS
1) 生成DashBoard
root@srv1:~# kubectl apply -f Kubernetes-dashboard.yaml
namespace/kubernetes-dashboard created
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
2) 确认状态
root@srv1:~# kubectl get pods -n kubernetes-dashboard -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
dashboard-metrics-scraper-8c47d4b5d-gt4mg 1/1 Running 0 74m 10.244.2.7 srv2.1000y.cloud <none> <none>
kubernetes-dashboard-5676d8b865-92g2q 1/1 Running 0 74m 10.244.1.6 srv2.1000y.cloud <none> <none>
3) 添加一个DashBoard管理帐户
root@srv1:~# kubectl create serviceaccount kube-dashboard-admin-sa -n kube-system
serviceaccount/kube-dashboard-admin-sa created
4) 赋权
root@srv1:~# kubectl create clusterrolebinding kube-dashboard-admin-sa --clusterrole=cluster-admin --serviceaccount=kube-system:kube-dashboard-admin-sa
clusterrolebinding.rbac.authorization.k8s.io/kube-dashboard-admin-sa created
5) 获取token
root@srv1:~# kubectl create token kube-dashboard-admin-sa -n kube-system --duration=87600h

6) 暴露DashBoard端口
root@srv1:~# kubectl get svc -n kubernetes-dashboard -o wide
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR
dashboard-metrics-scraper ClusterIP 10.106.116.226 <none> 8000/TCP 89m k8s-app=dashboard-metrics-scraper
kubernetes-dashboard ClusterIP 10.109.189.62 <none> 443/TCP 89m k8s-app=kubernetes-dashboard
root@srv1:~# kubectl patch svc -n kubernetes-dashboard kubernetes-dashboard -p '{"spec": {"type" : "NodePort"}}'
service/kubernetes-dashboard patched
root@srv1:~# kubectl get svc -n kubernetes-dashboard -o wide
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR
