kubeadm token create - Create bootstrap tokens on the server
kubeadm token create [OPTIONS]
This command will create a bootstrap token for you. You can specify the usages for this token, the "time to live" and an optional human friendly description.
The [token] is the actual token to write. This should be a securely generated random token of the form "[a-z0-9]{6}.[a-z0-9]{16}". If no [token] is given, kubeadm will generate a random token instead.

--description=""
A human friendly description of how this token is used.
--groups=[system:bootstrappers:kubeadm:default-node-token]
Extra groups that this token will authenticate as when used for authentication. Must match "\Asystem:bootstrappers:[a-z0-9:-]{0,255}[a-z0-9]\z"
--print-join-command=false
Instead of printing only the token, print the full 'kubeadm join' flag needed to join the cluster using the token.
