k8s部署dashborad

环境：

两台虚拟机，

10.10.20.203 部署docker、etcd、flannel、kube-apiserver、kube-controller-manager、kube-scheduler

10.10.20.206 部署docker、flannel、kubelet、kube-proxy

1、下载dashborad的镜像，并上传到私服，下载方式如下

docker pull index.tenxcloud.com/google_containers/kubernetes-dashboard-amd64

2、创建命名空间namespace.yaml

apiVersion: v1

kind: Namespace

metadata:

  name: kube-system

3、创建rc.yaml

apiVersion: v1

kind: ReplicationController

metadata:

  name: kubernetes-dashboard

  namespace: kube-system

  labels:

    k8s-app: kubernetes-dashboard

    version: latest

    kubernetes.io/cluster-service: "true"

spec:

  replicas:

  selector:

    k8s-app: kubernetes-dashboard

  template:

    metadata:

      labels:

        k8s-app: kubernetes-dashboard

        version: latest

        kubernetes.io/cluster-service: "true"

    spec:

      containers:

      - name: kubernetes-dashboard

        image: 10.10.20.202/library/kube-dashborad

        resources:

          # keep request = limit to keep this container in guaranteed class

          limits:

            cpu: 100m

            memory: 50Mi

          requests:

            cpu: 100m

            memory: 50Mi

        ports:

        - containerPort:

        args:

        -  --apiserver-host=http://10.10.20.203:8080

4、创建service.yaml

apiVersion: v1

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:

    targetPort:

5、创建命名空间、rc和service

kubectl create -f namespace.yaml

kubectl create -f rc.yaml

kubectl create -f service.yaml

6、查看命名空间

[root@k8s-master ui]# kubectl get namespace

NAME          STATUS    AGE

default       Active    19h

kube-system   Active    19h

7、查看pod

[root@k8s-master ui]# kubectl get pods --namespace=kube-system

NAME                         READY     STATUS    RESTARTS   AGE

kubernetes-dashboard-5q44n   /       Running             14s
