kubernetes启动dashboard

搭建k8s环境见：https://www.jianshu.com/p/9d8147f2952d

1. 从github下载dashboard yaml文件

从kubernetes/kubernetes仓库的下载

kubernetes/cluster/addons/dashboard/dashboard.yaml

，dashboard默认暴露的是cluster ip，如果我们想要在集群外面的集群上访问dashboard的话，就访问不了，修改dashboard.yaml的dashboard的service配置即可，如下：

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
    kubernetes.io/cluster-service: "true"
    addonmanager.kubernetes.io/mode: Reconcile
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  ports:
    - port: 443
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
  type: NodePort # 增加type字段为NodePort即可

2. 部署dashboard

kubectl apply -f dashboard.yaml

3. 配置dashboard

kubectl create serviceaccount dashboard-view -n kubernetes-dashboard # 创建sa
kubectl create clusterrolebinding dashboard-view --clusterrole=view --serviceaccount=dashboard-view # 创建clusterrolebingding
kubectl describe secrets -n kubernetes-dashboard $(kubectl -n kubernetes-dashboard  get secret | awk '/dashboard-view/{print $1}') # 获取secrets的token

4. 登录dashboard

kubectl get svc -n kubernetes-dashboard # 获取创建的svc

如图：用集群里任意一台node的ip地址加31786端口就可以访问dashboard了

选择token登录，输入上面获取到的token
