When you run this command on a worker, that worker leaves the swarm.
You can use the
--force option on a manager to remove it from the swarm.
However, this does not reconfigure the swarm to ensure that there are enough
managers to maintain a quorum in the swarm. The safe way to remove a manager
from a swarm is to demote it to a worker and then direct it to leave the quorum
--force. Only use
--force in situations where the swarm will
no longer be used after the manager leaves, such as in a single-node swarm.
Consider the following swarm, as seen from the manager:
$ docker node ls ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS 7ln70fl22uw2dvjn2ft53m3q5 worker2 Ready Active dkp8vy1dq1kxleu9g4u78tlag worker1 Ready Active dvfxp4zseq4s0rih1selh0d20 * manager1 Ready Active Leader
worker2, issue the following command from
$ docker swarm leave Node left the default swarm.
The node will still appear in the node list, and marked as
down. It no longer
affects swarm operation, but a long list of
down nodes can clutter the node
list. To remove an inactive node from the list, use the
