## 基础环境 ##

基本的K8S集群，可参考[我的文章][Link 1]

## 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
