一.kubernetes dashboard

kubernetes dashboard是k8s的web管理界面

二.安装

k8s的版本为1.5

1.创建dashboard-controller.yaml

[root@master dashboard]# cat dashboard-controller.yamlapiVersion: extensions/v1beta1kind: Deploymentmetadata:# Keep the name in sync with image version and# gce/coreos/kube-manifests/addons/dashboard counterparts name: kubernetes-dashboard-latest namespace: kube-systemspec: replicas: 1 template: metadata: labels: k8s-app: kubernetes-dashboard version: latest kubernetes.io/cluster-service: "true" 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://192.168.2.17:8080 livenessProbe: httpGet: path: / port: 9090 initialDelaySeconds: 30 timeoutSeconds: 30

ps:
上文中的--apiserver-host,这是master的地址

应用该配置文件:

#kubectl apply -f dashboard-controller.yaml

2.创建dashboard-service.yaml

[root@master dashboard]# cat dashboard-service.yamlkind: Servicemetadata: 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

应用该配置文件:

#kubectl apply -f dashboard-service.yaml

3.查看创建状况:

[root@master dashboard]# kubectl get pods -n=kube-systemNAME READY STATUS RESTARTS AGEkubernetes-dashboard-3708984300-cx0cz 1/1 Running 0 5h[root@master dashboard]# kubectl get svc -n=kube-systemNAME CLUSTER-IP EXTERNAL-IP PORT(S) AGEkubernetes-dashboard 10.254.46.214 <none> 80/TCP 25m

三.外部访问(请参见ingress)

1.创建kubernetes-dashboard-ingress.yaml

[root@master ingress]# cat kubernetes-dashboard-ingress.yamlapiVersion: extensions/v1beta1kind: Ingressmetadata: name: dashboard-ui-ingress namespace: kube-systemspec: rules: - host: ui.k8.ingress http: paths: - path: / backend: serviceName: kubernetes-dashboard servicePort: 80

ps

注意namespace,并不是默认值

应用配置文件

#kubectl apply -f kubernetes-dashboard-ingress.yaml

2.查看ingress

[root@master dashboard]# kubectl get ingress -n=kube-systemNAME HOSTS ADDRESS PORTS AGEdashboard-ui-ingress ui.k8.ingress 192.168.2.26 80 19m

3.做hosts

192.168.2.26 ui.k8.ingress

4.访问http://ui.k8.ingress, 应该能看到k8s的web管理界面
