## Description
|
|
|
|
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.
|
|
|
|
> **Note**
|
|
>
|
|
> This is a cluster management command, and must be executed on a swarm
|
|
> manager node. To learn about managers and workers, refer to the
|
|
> [Swarm mode section](https://docs.docker.com/engine/swarm/) in the
|
|
> documentation.
