# 操作环境 #

操作环境同 [《 Centos7 下Kubernetes集群安装部署》][Centos7 _Kubernetes],注意要将flannel网络配置好，否则会出问题。

# 操作步骤 #

1.在2个节点上手动下载kubernetes dashboard image

[root@k8s-node2 ~]# docker pull  docker.io/mritd/kubernetes-dashboard-amd64
    Using default tag: latest
    Trying to pull repository docker.io/mritd/kubernetes-dashboard-amd64 ... 
    latest: Pulling from docker.io/mritd/kubernetes-dashboard-amd64
    Digest: sha256:377d905c758d08674fd434e567fbfb4411f64a52090d0de7f64fd70b72b2fbeb

2.在k8s-master节点上编辑kubernetes-dashboard.yaml文件如下：

[root@k8s-master yaml]# vi kubernetes-dashboard.yaml 
    apiVersion: extensions/v1beta1
    kind: Deployment
    metadata:
    # Keep the name in sync with image version and
    # gce/coreos/kube-manifests/addons/dashboard counterparts
      name: kubernetes-dashboard
      namespace: kube-system
    spec:
      replicas: 1
      template:
        metadata:
          labels:
            k8s-app: kubernetes-dashboard
            version: latest
            kubernetes.io/cluster-service: "true"
        spec:
          containers:
          - name: kubernetes-dashboard
            image: docker.io/mritd/kubernetes-dashboard-amd64
            resources:
              # keep request = limit to keep this container in guaranteed class
              limits:
                cpu: 100m
                memory: 50Mi
              requests:
                cpu: 100m
                memory: 50Mi
            ports:
            - containerPort: 9090
            args:
             - --apiserver-host=http://10.10.200.224:8080
            livenessProbe:
              httpGet:
                path: /
                port: 9090
              initialDelaySeconds: 30
              timeoutSeconds: 30
    ---
    kind: Service
    metadata:
      name: kubernetes-dashboard
      namespace: kube-system
      labels:
        k8s-app: kubernetes-dashboard
        kubernetes.io/cluster-service: "true"
    spec:
      selector:
        k8s-app: kubernetes-dashboard
      ports:
      - port: 80
        targetPort: 9090

3.启动kubernetes-dashboard

[root@k8s-master yaml]# kubectl create -f kubernetes-dashboard.yaml

4.访问kuberne-dashboard，http://10.10.200.224:8080/ui
