  # Run join pre-flight checks using a config file.
  kubeadm join phase preflight --config kubeadm-config.yml


      --apiserver-advertise-address string            If the node should host a new control plane instance, the IP address the API Server will advertise it's listening on. If not set the default network interface will be used.
      --apiserver-bind-port int32                     If the node should host a new control plane instance, the port for the API Server to bind to. (default 6443)
      --certificate-key string                        Use this key to decrypt the certificate secrets uploaded by init.
      --config string                                 Path to kubeadm config file.
      --cri-socket string                             Path to the CRI socket to connect. If empty kubeadm will try to auto-detect this value; use this option only if you have more than one CRI installed or if you have non-standard CRI socket.
      --discovery-file string                         For file-based discovery, a file or URL from which to load cluster information.
      --discovery-token string                        For token-based discovery, the token used to validate cluster information fetched from the API server.
      --discovery-token-ca-cert-hash strings          For token-based discovery, validate that the root CA public key matches this hash (format: "<type>:<value>").
      --discovery-token-unsafe-skip-ca-verification   For token-based discovery, allow joining without --discovery-token-ca-cert-hash pinning.
      --experimental-control-plane                    Create a new control plane instance on this node
  -h, --help                                          help for preflight
      --ignore-preflight-errors strings               A list of checks whose errors will be shown as warnings. Example: 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks.
      --node-name string                              Specify the node name.
      --tls-bootstrap-token string                    Specify the token used to temporarily authenticate with the Kubernetes Control Plane while joining the node.
      --token string                                  Use this token for both discovery-token and tls-bootstrap-token when those values are not provided.
