本文首發自個人博客：https://blog.smile13.com/articles/2019/01/14/1547457021341.html

此操作在任意一個master上進行

1.下載配置文件

wget https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml

2.修改配置文件

------------------- Dashboard Deployment -------------------
containers:
      - name: kubernetes-dashboard
        imagePullPolicy: IfNotPresent
        image: registry.cn-hangzhou.aliyuncs.com/google_containers/kubernetes-dashboard-amd64:v1.10.1

# ------------------- Dashboard Service ------------------- #

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kube-system
spec:
  type: NodePort
  ports:
    - port: 443
      targetPort: 8443
      nodePort: 30080
  selector:
    k8s-app: kubernetes-dashboard

 

3.部署kubernetes-dashboard

kubeadm-config.yaml  kubernetes-dashboard.yaml
[root@k8s01 k8s-install]# kubectl create -f kubernetes-dashboard.yaml
secret/kubernetes-dashboard-certs created
serviceaccount/kubernetes-dashboard created
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
deployment.apps/kubernetes-dashboard created
service/kubernetes-dashboard created

4.查看dashboard部署情況

[root@k8s01 k8s-install]# kubectl get pods -n kube-system

如果創建不對的話可以使用kubectl  delete  -f  kubernetes-dashboard.yaml刪掉，然後重新創建

5.創建serviceaccount 用於登陸dashboard

kubectl create serviceaccount dashboard-admin -n kube-system

6.創建clusterrolebinding

kubectl create clusterrolebinding cluster-dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin

7.查看生成的secret的token

###查看secret
[root@k8s01 ~]# kubectl  get  secret -n kube-system|grep dashboard-admin
dashboard-admin-token-4z7zs                      kubernetes.io/service-account-token   3      27s
>
###根據secret名稱查找token
[root@k8s01 ~]# kubectl describe secret dashboard-admin-token-4z7zs -n kube-system
Name:         dashboard-admin-token-4z7zs
Namespace:    kube-system
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: dashboard-admin
              kubernetes.io/service-account.uid: ab39b60b-19a2-11e9-9579-525400837d49

Type:  kubernetes.io/service-account-token

Data
====
namespace:  11 bytes
token:      eyJhbGciOiJSUzI1NiIsImtpZCI6IiJ9.eyJpc3MiOiJrdWJlcm5ldGVzL3NlcnZpY2VhY2NvdW50Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9uYW1lc3Bhxxxxxxxxxxx...(省略)
ca.crt:     1025 bytes

8.登錄dashboard（使用firefox）

打開對應的地址（https://192.168.158.138:30080），選擇token登錄，使用上面的token登錄即可。
