kubernetes1.16安装dashboard2.0

背景：由于之前本地部署的k8s当时由于条件限制，只在一台32G的主机上装安装vmware，并在上面安装虚拟机，每个虚拟机只有8G内存，稍微跑点东西就卡住了，这段时间在领导的支持下买了三台32G的组装机，用于部署本地测试环境。部署完1.16后才发现，1.16开始有一些变化，按照以前的yaml编排文件和img镜像要会报rbac权限 问题，由于对K8s并不是很精通，在折腾两天后终于安装上了，废话不多说，看下文：
1、直接 kubectl apply google上面搜索到的一个yaml编排文件

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml

---
---
kubectl -n kubernetes-dashboard edit svc kubernetes-dashboard
spec:
clusterIP: 10.0.0.38
externalTrafficPolicy: Cluster
ports:
nodePort: 30220
port: 443
protocol: TCP
targetPort: 8443
selector:
k8s-app: kubernetes-dashboard
sessionAffinity: None
type: NodePort

3、获取token用于在浏览器访问时的验证

kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')

4、使用浏览器进行访问，粘贴上面得到的token
