InformationDo not use token based authentication.
The token-based authentication utilizes static tokens to authenticate requests to the apiserver. The tokens are stored in clear-text in a file on the apiserver, and cannot be revoked or rotated without restarting the apiserver. Hence, do not use static token-based authentication.
SolutionFollow the documentation and configure alternate mechanisms for authentication. Then, edit the API server pod specification file '/etc/kubernetes/manifests/kube-apiserver.yaml' on the master node and remove the '--token-auth-file=' parameter.
You will have to configure and use alternate authentication mechanisms such as certificates. Static token based authentication could not be used.
