  name: kube-system-default
  labels:
    k8s-app: kube-system
roleRef:
  apiGroup: rbac.authorization.k8s.io

  namespace: kube-system
  labels:
    k8s-app: kube-system
  annotations:
    kubernetes.io/service-account.name: default
type: kubernetes.io/service-account-token

kubectl config set-credentials docker-desktop --token="${TOKEN}"
echo $TOKEN
