Generates bootstrap tokens used to join a node to a cluster


Bootstrap tokens are used for establishing bidirectional trust between a node joining the cluster and a the control-plane node.

This command makes all the configurations required to make bootstrap tokens works and then creates an initial token.

kubeadm init phase bootstrap-token [flags]


  # Make all the bootstrap token configurations and create an initial token, functionally
  # equivalent to what generated by kubeadm init.
  kubeadm init phase bootstrap-token


      --config string       Path to a kubeadm configuration file.
  -h, --help                help for bootstrap-token
      --kubeconfig string   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. (default "/etc/kubernetes/admin.conf")
      --skip-token-print    Skip printing of the default bootstrap token generated by 'kubeadm init'.
