安装Kubernetes-dashboard
一、准备yaml文件
vim kubernetes-dashboard.yaml
| # ------------------- Dashboard Deployment ------------------- #
kind: Deployment apiVersion: apps/v1 metadata: labels: k8s-app: kubernetes-dashboard name: kubernetes-dashboard namespace: kube-system spec: replicas: 1 selector: matchLabels: k8s-app: kubernetes-dashboard template: metadata: labels: k8s-app: kubernetes-dashboard spec: containers: - name: kubernetes-dashboard image: k8s.gcr.io/kubernetes-dashboard-amd64:v1.6.3 ports: - containerPort: 9090 args: - --apiserver-host=http://192.168.13.117:8080 livenessProbe: httpGet: path: / port: 9090 initialDelaySeconds: 30 timeoutSeconds: 30
--- # ------------------- Dashboard Service ------------------- #
kind: Service apiVersion: v1 metadata: labels: k8s-app: kubernetes-dashboard name: kubernetes-dashboard namespace: kube-system spec: type: NodePort ports: - port: 80 targetPort: 9090 selector: k8s-app: kubernetes-dashboard |
注意：
1、需要修改--apiserver-host=http://192.168.13.117:8080，改为自己kubernetes集群的master的apiserver地址
2、需要提前下载好k8s.gcr.io/kubernetes-dashboard-amd64:v1.6.3镜像，在国内无法访问google，所以先在阿里云上下载好镜像，然后通过docker tag重新打成k8s.gcr.io/kubernetes-dashboard-amd64:v1.6.3的标签。
二、启动dashboard
kubectl create -f kubernetes-dashboard.yaml
三、校验
[[email protected] cfg]# kubectl get deployment --all-namespaces
NAMESPACE NAME READY UP-TO-DATE AVAILABLE AGE
default nginx 1/1 1 1 4d6h
kube-system kubernetes-dashboard 1/1 1 1 18m
[[email protected] cfg]# kubectl get svc --all-namespaces
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default kubernetes ClusterIP 10.10.10.1 <none> 443/TCP 4d7h
default nginx NodePort 10.10.10.59 <none> 88:30772/TCP 4d6h
kube-system kubernetes-dashboard NodePort 10.10.10.161 <none> 80:30329/TCP 18m
[[email protected] cfg]# kubectl get pod -o wide --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
default nginx-7cdbd8cdc9-cl4jr 1/1 Running 0 4d6h 172.17.91.2 192.168.13.126 <none> <none>
kube-system kubernetes-dashboard-5fc67b7585-g6l8q 1/1 Running 0 18m 172.17.91.3 192.168.13.126 <none> <none>
发现kubernetes-dashboard已经处于Running状态，并且随机生成的NodePort端口为30329，并且Pod部署在192.168.13.126 node上。
四、访问
通过浏览器访问：http://192.168.13.126:30329，其中192.168.13.126为node节点的ip地址，端口30329为随机生成的NodePort端口，即可看到下面页面：
