Creating sample user, reference guide on GitHub
Create a config file dashboard-adminuser.yaml for Service Account and ClusterRoleBinding
---
apiVersion: v1
kind: ServiceAccount
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard-admin
namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
name: kubernetes-dashboard-admin
labels:
k8s-app: kubernetes-dashboard
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: kubernetes-dashboard-admin
namespace: kube-system
Create user and role binding
kubectl apply -f dashboard-adminuser.yaml
Bearer Token
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep kubernetes-dashboard-admin-token | awk '{print $1}')
Name: kubernetes-dashboard-admin-token-ngv5v
Namespace: kube-system
Labels: <none>
Annotations: kubernetes.io/service-account.name: kubernetes-dashboard-admin
