kubeadm-token-create - Man Page

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.

--certificate-key="" When used together with '--print-join-command', print the full 'kubeadm join' flag needed to join the cluster as a control-plane. To create a new certificate key you must use 'kubeadm init phase upload-certs --upload-certs'.

--config="" Path to a kubeadm configuration file.

--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.

--ttl=24h0m0s The duration before the token is automatically deleted (e.g. 1s, 2m, 3h). If set to '0', the token will never expire

--usages=[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]

--azure-container-registry-config="" Path to the file containing Azure container registry configuration information.

--dry-run=false Whether to enable dry-run mode or not

--kubeconfig="/etc/kubernetes/admin.conf" The kubeconfig file to use when talking to the cluster. If the flag is not set, a set of standard locations can be searched for an existing kubeconfig file.

--rootfs="" [EXPERIMENTAL] The path to the 'real' host root filesystem.

--version=false --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version
