kubenetes 1.16.0安装kubernetes-dashboard v2.0.0-beta4
kubenetes github ：https://github.com/kubernetes/dashboard/releases
kubenetes官网：https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/
本人安装kubenetes 1.16.0，刚开始使用kubernetes-dashboard v1.10.1安装后，首页访问接口报错404，怀疑是版本不兼容问题。后面发现kubernetes-dashboard最新版本已经是v2.0.0-beta4。并且kubenetes官方文档安装dashboard的描述，指明部署方法
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta4/aio/deploy/recommended.yaml
https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta4/aio/deploy/recommended.yaml
所以kubenetes v1.16.0 应该使用新版dashboard ui才兼容
查看github，用到的镜像有两个dashboard:v2.0.0-beta4、metrics-scraper:v1.0.1
kubernetesui/dashboard:v2.0.0-beta4kubernetesui/metrics-scraper:v1.0.1先拉取镜像，本人使用的docker版本19.03.2
docker pull kubernetesui/dashboard:v2.0.0-beta4kubernetesui/metrics-scraper:v1.0.1拉成功后
获取yaml文件
https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta4/aio/deploy/recommended.yaml修改recommended.yaml文件，为了方便访问，修改kubernetes-dashboard的Service定义，指定Service的type类型为NodeType，指定nodePort端口
kind: Service
apiVersion: v1
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kubernetes-dashboard
spec:
type: NodePort # 改成NodePort
ports:
- port: 443
targetPort: 8443
nodePort: 31001 # 指定nodePort端口
selector:
k8s-app: kubernetes-dashboard
注：dashboard-metrics-scraper的Service不需要修改从配置文件可以看到，它还创建了ServiceAccount帐号
apiVersion: v1
kind: ServiceAccount
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kubernetes-dashboard还创建了ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: kubernetes-dashboard
namespace: kubernetes-dashboard
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: kubernetes-dashboard
subjects:
- kind: ServiceAccount
name: kubernetes-dashboard
namespace: kubernetes-dashboard
