kubernetes之kube-ui安装配置

本文主要是介绍kubernetes之kube-ui安装配置，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

kube-ui是k8s提供的web管理界面，可以展示节点的内存、CPU、磁盘、Pod、RC、SVC等信息。

此次安装的是kubernetes-dashboard 1.6中文版本，注意更换kube-ui的docker源，或者可以手动拉取

1.编辑kube-dashboard-rc.yml定义文件
[root@master kube-dashboard]# vi dashboard-controller.yaml

  
 apiVersion: extensions/v1beta1 
kind: Deployment 
metadata: 
  name: kubernetes-dashboard 
  namespace: kube-system 
  labels: 
    k8s-app: kubernetes-dashboard 
    kubernetes.io/cluster-service: "true" 
spec: 
  selector: 
    matchLabels: 
      k8s-app: kubernetes-dashboard 
  template: 
    metadata: 
      labels: 
        k8s-app: kubernetes-dashboard 
      annotations: 
        scheduler.alpha.kubernetes.io/critical-pod: '' 
        scheduler.alpha.kubernetes.io/tolerations: '[{"key":"CriticalAddonsOnly", "operator":"Exists"}]' 
    spec: 
      containers: 
      - name: kubernetes-dashboard 
 image: bestwu/kubernetes-dashboard-amd64:v1.6.3
        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://192.168.155.5:8080
        livenessProbe:
          httpGet:
            path: /
            port: 9090
          initialDelaySeconds: 30
          timeoutSeconds: 30
  

•创建Pod

[root@master kube-dashboard]# kubectl create -f dashboard-controller.yaml

2.编辑dashboard-service.yaml定义文件
[root@master kube-dashboard]# vi dashboard-service.yaml

apiVersion: v1
kind: Service
metadata:name: kubernetes-dashboardnamespace: kube-systemlabels:k8s-app: kubernetes-dashboardkubernetes.io/cluster-service: "true"
spec:selector:k8s-app: kubernetes-dashboardports:- port: 80targetPort: 9090

•创建Service

[root@master kube-dashboard]# kubectl create -f dashboard-service.yaml

3.查看pod运行状态

[root@master kube-dashboard]# kubectl get pod --namespace=kube-system #按照命名空间查看运行状态

可以看到当前pod会一直处于ContainerCreating状态

[root@master kube-dashboard]# kubectl describe pod --namespace=kube-system kubernetes-dashboard-s92m

运行命令：

yum install *rhsm* -y

然后手动拉取镜像

docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest

再次运行pod状态查看命令：运行正常

4.访问192.168.155.5:8080/ui(也就是master节点)，会自动跳转到http://192.168.155.5:8080/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard/#/dashboard效果如下图
