Create token for Kubernetes dashboard

Since Kubernetes v1.24.0, there is no auto-generation of secret-based service Account token due to security reason. You need to create a service Account and an optional long-lived Bearer Token for the service Account.

kubectl --kubeconfig /custom/path/kube.conf apply -f - <
apiVersion: v1
kind: ServiceAccount
metadata:
  name: kubernetes-dashboard-admin-user
  namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: kubernetes-dashboard-admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: kubernetes-dashboard-admin-user
  namespace: kubernetes-dashboard
---
apiVersion: v1
kind: Secret
type: kubernetes.io/service-account-token
metadata:
  name: kubernetes-dashboard-token
  namespace: kubernetes-dashboard
  annotations:
    kubernetes.io/service-account.name: kubernetes-dashboard-admin-user
EOF

Token for dashboard login can be retrieved using following command

kubectl --kubeconfig /custom/path/kube.conf describe secret $(kubectl --kubeconfig /custom/path/kube.conf get secrets -n kubernetes-dashboard | grep kubernetes-dashboard-token | awk '{print $1}') -n kubernetes-dashboard
