rules:
- apiGroups: [""]
  resources:
  - namespaces
  - nodes
  - nodes/proxy
  - services
  - endpoints
  - pods
  verbs: ["get", "list", "watch"]
- apiGroups:
  - extensions
  resources:

  namespace: default
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:

roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: ktadmin
subjects:
- kind: ServiceAccount
  name: ktadmin
  namespace: default

And Create new Service And Deployment:

apiVersion: v1
kind: Service
metadata:
  name: kt-dashboard
spec:
  ports:
  - port: 80
    targetPort: 80
  selector:
    app: kt-dashboard

kind: Deployment
metadata:
  labels:
    app: kt-dashboard
  name: kt-dashboard
spec:
  replicas: 1
  selector:
    matchLabels:
      app: kt-dashboard
  template:
    metadata:
      labels:
        app: kt-dashboard
    spec:
      serviceAccount: ktadmin
      containers:
      - image: registry.cn-hangzhou.aliyuncs.com/rdc-incubator/kt-connect-dashboard:stable
        imagePullPolicy: Always
        name: dashboard
        ports:
        - containerPort: 80

You can save below content to rbac-setup.yaml and dashboard.yaml，and deploy to Kubernetes cluster:

kubectl apply -f rbac-setup.yaml
kubectl apply -f dashboard.yaml

Or use shell as follow:

kubectl apply -f https://rdc-incubators.oss-cn-beijing.aliyuncs.com/dashboard/stable/rbac.yaml
kubectl apply -f https://rdc-incubators.oss-cn-beijing.aliyuncs.com/dashboard/stable/dashboard.yaml

After all components up, you can view in local:

$ kubectl port-forward deployments/kt-dashboard 8000:80   
Forwarding from 127.0.0.1:8000 -> 80
Forwarding from [::1]:8000 -> 80

And then open http://127.0.0.1:8000
