kubeadm reset [flags]

Options

--cert-dir string     Default: "/etc/kubernetes/pki"
The path to the directory where the certificates are stored. If specified, clean this directory.
--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.
-f, --force
Reset the node without prompting for confirmation.
-h, --help
help for reset
--ignore-preflight-errors stringSlice
A list of checks whose errors will be shown as warnings. Example: 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks.
--kubeconfig string     Default: "/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.

Options inherited from parent commands

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

External etcd clean up!

kubeadm reset will not delete any etcd data if external etcd is used. This means that if you run kubeadm init again using the same etcd endpoints, you will see state from previous clusters.

To wipe etcd data it is recommended you use a client like etcdctl, such as:

etcdctl del "" --prefix

See the etcd documentation for more information.
