【k8s弹性伸缩】dashboard的安装部署

kubernetes dashboard是kubernetes官方提供的web管理界面,通过dashboard可以很方便地查看集群的各种资源.以及修改资源编排文件,对集群进行扩容操作,查看日志等.功能非常强大。

在master节点中拉取dashboard镜像，并推送到私有仓库中。

docker pull registry.cn-hangzhou.aliyuncs.com/kubeapps/k8s-gcr-kubernetes-dashboard-amd64:v1.4.1
docker tag registry.cn-hangzhou.aliyuncs.com/kubeapps/k8s-gcr-kubernetes-dashboard-amd64:v1.4.1 192.168.1.5:5000/kubernetes-dashboard-amd64:v1.4.1
docker push 192.168.1.5:5000/kubernetes-dashboard-amd64:v1.4.1

 修改创建deployment文件dashboard-deploy.yaml，注意ip和命名空间，并执行kubectl create -f dashboard-deploy.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-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: 192.168.1.5:5000/kubernetes-dashboard-amd64:v1.4.1
        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://192.168.1.5:8080
        livenessProbe:
          httpGet:
            path: /
            port: 9090
          initialDelaySeconds: 30
          timeoutSeconds: 30

  修改创建svc文件，并执行kubectl create -f dashboard-svc.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

  查看所有pod和service，注意命名空间

kubectl get all --namespace=kube-system -o wide

  看到dashboard的svc和rs是关联起来的

    则访问http://192.168.1.5:8080/

 

    再访问 http://192.168.1.5:8080/ui  则自动跳转到dashboard的主页如下

   dashboard安装成功！
