| Resetting a Machine |
From time to time, it may be beneficial to reset a Talos machine to its "original" state. Bear in mind that this is a destructive action for the given machine. Doing this means removing the machine from Kubernetes, Etcd (if applicable), and clears any data on the machine that would normally persist a reboot.
The API command for doing this is talosctl reset.
There are a couple of flags as part of this command:
Flags:
--graceful if true, attempt to cordon/drain node and leave etcd (if applicable) (default true)
--reboot if true, reboot the node after resetting instead of shutting down
The graceful flag is especially important when considering HA vs. non-HA Talos clusters.
If the machine is part of an HA cluster, a normal, graceful reset should work just fine right out of the box as long as the cluster is in a good state.
However, if this is a single node cluster being used for testing purposes, a graceful reset is not an option since Etcd cannot be "left" if there is only a single member.
In this case, reset should be used with --graceful=false to skip performing checks that would normally block the reset.
