基础环境

基本的K8S集群，可参考我的文章

部署步骤

1. dashboard-controller.yaml

   apiVersion: extensions/v1beta1
   kind: Deployment
   metadata:
     name: kubernetes-dashboard
     namespace: kube-system
     labels:
       k8s-app: kubernetes-dashboard
       kubernetes.io/cluster-service: "true"
       addonmanager.kubernetes.io/mode: Reconcile
   spec:
     selector:
       matchLabels:
         k8s-app: kubernetes-dashboard
     template:
       metadata:
         labels:
           k8s-app: kubernetes-dashboard
         annotations:
           scheduler.alpha.kubernetes.io/critical-pod: ''
       spec:
         serviceAccountName: dashboard
         containers:
         - name: kubernetes-dashboard
           image: kingdragon/kubernetes-dashboard-amd64:v1.6.3
           resources:
             limits:
               cpu: 100m
               memory: 50Mi
             requests:
               cpu: 100m
               memory: 50Mi
           ports:
           - containerPort: 9090
           livenessProbe:
             httpGet:
               path: /
               port: 9090
             initialDelaySeconds: 30
             timeoutSeconds: 30
         tolerations:
         - key: "CriticalAddonsOnly"
           operator: "Exists"
   

   补充：注意更改镜像仓库地址为你的镜像地址

2. dashboard-rbac.yaml

   apiVersion: v1
   kind: ServiceAccount
   metadata:
     name: dashboard
     namespace: kube-system
   
   ---
   
   kind: ClusterRoleBinding
   apiVersion: rbac.authorization.k8s.io/v1beta1
   metadata:
     name: dashboard
   subjects:
     - kind: ServiceAccount
       name: dashboard
       namespace: kube-system
   roleRef:
     kind: ClusterRole
     name: cluster-admin
     apiGroup: rbac.authorization.k8s.io
   

   补充：绑定的集群超级用户cluster-admin，按需求更改

3. dashboard-service.yaml

   apiVersion: v1
   kind: Service
   metadata:
     name: kubernetes-dashboard
     namespace: kube-system
     labels:
       k8s-app: kubernetes-dashboard
       kubernetes.io/cluster-service: "true"
       addonmanager.kubernetes.io/mode: Reconcile
   spec:
     type: NodePort 
     selector:
       k8s-app: kubernetes-dashboard
     ports:
     - port: 80
       targetPort: 9090
   

   补充：这里服务的暴露方式用的nodeport方式。还有其他模式，自行尝试。

4. 执行所有文件

   $ pwd
   /root/kubernetes/cluster/addons/dashboard
   $ ls *.yaml
   dashboard-controller.yaml  dashboard-service.yaml  dashboard-rbac.yaml
   $ kubectl create -f  .
   service "kubernetes-dashboard" created
   deployment "kubernetes-dashboard" created
   clusterrolebinding.rbac.authorization.k8s.io/dashboard created
   

5. 查看执行结果

   $ kubectl get services kubernetes-dashboard -n kube-system
   NAME                   CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
   kubernetes-dashboard   10.254.224.130   <nodes>       80:30312/TCP   25s
   

6. 访问dashboard

   访问nodeip:30312
