Usage: consul force-leave [options] name
|
|
|
|
Forces a member of a Consul cluster to enter the "left" state. Note
|
|
that if the member is still actually alive, it will eventually rejoin
|
|
the cluster. This command is most useful for cleaning out "failed" nodes
|
|
that are never coming back. If you do not force leave a failed node,
|
|
Consul will attempt to reconnect to those failed nodes for some period of
|
|
time before eventually reaping them.
