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.

kubeadm token create [token]

Options

--config string
Path to kubeadm config file (WARNING: Usage of a configuration file is experimental)
--description string
A human friendly description of how this token is used.
--groups stringSlice     Default: [system:bootstrappers:kubeadm:default-node-token]
Extra groups that this token will authenticate as when used for authentication. Must match "system:bootstrappers:[a-z0-9:-]{0,255}[a-z0-9]".
-h, --help

--print-join-command

--ttl duration     Default: 24h0m0s

--usages stringSlice     Default: [signing,authentication]
Describes the ways in which this token can be used. You can pass --usages multiple times or provide a comma separated list of options. Valid options: [signing,authentication].
