» Serf Force Leave

Command: serf force-leave

The force-leave command forces a member of a Serf cluster to enter the "left" state. Note that if the member is still actually alive, it will eventually rejoin the cluster. The true purpose of this method is to force remove "failed" nodes.

Serf periodically tries to reconnect to "failed" nodes in case it is a network partition. After some configured amount of time (by default 24 hours), Serf will reap "failed" nodes and stop trying to reconnect. The force-leave command can be used to transition the "failed" nodes to "left" nodes more quickly.

Usage: serf force-leave [options] node

The following command-line options are available for this command. Every option is optional:

• -rpc-addr - Address to the RPC server of the agent you want to contact to send this command. If this isn't specified, the command will contact "127.0.0.1:7373" which is the default RPC address of a Serf agent. This option can also be controlled using the SERF_RPC_ADDR environment variable.

• -rpc-auth - Optional RPC auth token. If the agent is configured to use an auth token, then this must be provided or the agent will refuse the command. This option can also be controlled using the SERF_RPC_AUTH environment variable.

• -prune - Forcibly removes a member of the Serf cluster from the member list completely
