Create bootstrap tokens on the server.
Synopsis
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.
