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
