Unlocks a locked manager using a user-supplied unlock key. This command must be
|
|
used to reactivate a manager after its Docker daemon restarts if the autolock
|
|
setting is turned on. The unlock key is printed at the time when autolock is
|
|
enabled, and is also available from the `docker swarm unlock-key` command.
|
|
|
|
|
|
```bash
|
|
$ docker swarm unlock
|
|
Please enter unlock key:
|
|
```
