When you run this command on a worker, that worker leaves the swarm.

You can use the `--force` option to 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
|
|
|
|
without using `--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:
|

|
|
|
```bash
|
|
|
|
$ docker node ls

|
|
|

|

|
2016-06-13 22:57:19 -04:00

|
|
```
|
|
|
|
|

|
|
|
To remove `worker2`, issue the following command from `worker2` itself:
|
2016-06-13 22:57:19 -04:00
|
|
|
```bash
|
|
|
|
$ docker swarm leave
|
|
|
|
Node left the default swarm.
|
|
|
|
```
|

|
|
|
To remove an inactive node, use the [`node rm`](node_rm.md) command instead.
