Kubernetes Dashboard安装

1.安装

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml   ###卸载使用delete

2.查看Deployment和Service

fxx2@kube-node-1:~$ sudo kubectl --namespace=kubernetes-dashboard get service kubernetes-dashboard
NAME                   TYPE       CLUSTER-IP     EXTERNAL-IP   PORT(S)         AGE
kubernetes-dashboard   NodePort   10.107.42.57   <none>        443:32149/TCP   36h

###sudo kubectl --namespace=kubernetes-dashboard get deployment kubernetes-dashboard

3.修改service类型为NodePort

sudo kubectl --namespace=kubernetes-dashboard edit service kubernetes-dashboard
....
  selector:
    k8s-app: kubernetes-dashboard
  sessionAffinity: None
  type: NodePort   ###此处
....

4.创建Service Account和ClusterRoleBinding

sudo kubectl apply -f dashboard-adminuser.yaml   ###如下
fxx2@kube-node-1:~$ cat dashboard-adminuser.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kubernetes-dashboard

---

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kubernetes-dashboard

5.查看token

kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep admin-user | awk '{print $1}')

6.访问

https://<master_ip>:<service_port>，选择使用token登陆。
