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
安装kubernetes dashboard
