kubernetes（k8s）第六部分之K8s部署dashboard

【1】通过search查找镜像并拉取镜像

[root@random random]# docker search kubernetes-dashboard

[root@random random]# docker pull siriuszg/kubernetes-dashboard-amd64

【2】将镜像打包并通过scp发给master节点

[root@random ~]# docker save -o kubernetes-dashboard-amd64.tar  siriuszg/kubernetes-dashboard-amd64:latest

【3】在master节点加载镜像

[root@k8s-master ~]# docker load -i kubernetes-dashboard-amd64.tar

[root@k8s-master ~]# docker tag siriuszg/kubernetes-dashboard-amd64 registry:5000/kubernetes-dashboard-amd64

【4】将镜像上传到镜像仓库

[root@k8s-master ~]# docker push registry:5000/kubernetes-dashboard-amd64

【5】创建dashboard.yaml文件

[root@k8s-master ~]# cat dashboard.yaml 
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: kubernetes-dashboard-latest
  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: registry:5000/kubernetes-dashboard-amd64
        resources:
          limits:
            cpu: 100m
            memory: 50Mi
          requests:
            cpu: 100m
            memory: 50Mi
        ports:
        - containerPort: 9090
        args:
         -  --apiserver-host=http://172.25.37.11:8080
        livenessProbe:
          httpGet:
            path: /
            port: 9090
          initialDelaySeconds: 30
          timeoutSeconds: 30

【6】创建dashboardsvc.yaml文件

[root@k8s-master ~]# cat dashboardsvc.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: 80
    targetPort: 9090

【7】创建pod和service

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

[root@k8s-master ~]# kubectl create -f dashboardsvc.yaml

【8】查看dashboard部署情况

[root@k8s-master ~]# kubectl get svc --all-namespaces

[root@k8s-master ~]# kubectl get pod  -o wide  --all-namespaces

[root@k8s-master ~]# kubectl get deployment --all-namespaces

【9】执行下面的指令，让172.25.37.11可以通过172.25.37.11:8001/ui的方式访问dashboard

[root@k8s-master ~]# kubectl proxy --address=172.25.37.11 --disable-filter=true

【10】删除

[root@k8s-master ~]# kubectl delete svc  kubernetes-dashboard --namespace=kube-systemservice "kubernetes-dashboard" deleted

[root@k8s-master ~]# kubectl delete deployment kubernetes-dashboard-latest --namespace=kube-systemdeployment "kubernetes-dashboard-latest" deleted

[root@k8s-master ~]#
