NAME

kubeadm join phase preflight - Run join pre-flight checks

SYNOPSIS

kubeadm join phase preflight [OPTIONS]

DESCRIPTION

Run pre-flight checks for kubeadm join.

OPTIONS

--apiserver-advertise-address=""
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=6443
If the node should host a new control plane instance, the port for the API Server to bind to.

--certificate-key=""
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.

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

--control-plane=false
Create a new control plane instance on this node

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

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

--discovery-token-ca-cert-hash=[]
For token-based discovery, validate that the root CA public key matches this hash (format: ":").

--discovery-token-unsafe-skip-ca-verification=false
For token-based discovery, allow joining without --discovery-token-ca-cert-hash pinning.

--dry-run=false
Don't apply any changes; just output what would be done.

--ignore-preflight-errors=[]
A list of checks whose errors will be shown as warnings. Example: 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks.

--node-name=""
Specify the node name.

--tls-bootstrap-token=""
Specify the token used to temporarily authenticate with the Kubernetes Control Plane while joining the node.

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

OPTIONS INHERITED FROM PARENT COMMANDS

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

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

EXAMPLE

  # Run join pre-flight checks using a config file.
