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.

If the node should host a new control plane instance, the port for the API Server to bind to.

Use this key to decrypt the certificate secrets uploaded by init. The certificate key is a hex encoded string that is an AES key of size 32 bytes.

Path to a kubeadm configuration file.

Create a new control plane instance on this node

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.

For file-based discovery, a file or URL from which to load cluster information.

For token-based discovery, the token used to validate cluster information fetched from the API server.

For token-based discovery, validate that the root CA public key matches this hash (format: "<type>:<value>").

For token-based discovery, allow joining without --discovery-token-ca-cert-hash pinning.

Don't apply any changes; just output what would be done.

help for preflight

A list of checks whose errors will be shown as warnings. Example: 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks.

Specify the node name.

Specify the token used to temporarily authenticate with the Kubernetes Control Plane while joining the node.

Use this token for both discovery-token and tls-bootstrap-token when those values are not provided.

The path to the 'real' host root filesystem. This will cause kubeadm to chroot into the provided path.
