An unlock key is a secret key needed to unlock a manager after its Docker daemon restarts. These keys are only used when the autolock feature is enabled for the swarm.

You can view or rotate the unlock key using swarm unlock-key. To view the key, run the docker swarm unlock-key command without any arguments:

利用例

$ docker swarm unlock-key

To unlock a swarm manager after it restarts, run the `docker swarm unlock`
command and provide the following key:

    SWMKEY-1-fySn8TY4w5lKcWcJPIpKufejh9hxx5KYwx6XZigx3Q4

Remember to store this key in a password manager, since without it you
will not be able to restart the manager.

Use the --rotate flag to rotate the unlock key to a new, randomly-generated key:

$ docker swarm unlock-key --rotate

Successfully rotated manager unlock key.

To unlock a swarm manager after it restarts, run the `docker swarm unlock`
command and provide the following key:

    SWMKEY-1-7c37Cc8654o6p38HnroywCi19pllOnGtbdZEgtKxZu8

Remember to store this key in a password manager, since without it you
will not be able to restart the manager.

The -q (or --quiet) flag only prints the key:

$ docker swarm unlock-key -q

SWMKEY-1-7c37Cc8654o6p38HnroywCi19pllOnGtbdZEgtKxZu8

--rotate

This flag rotates the unlock key, replacing it with a new randomly-generated key. The old unlock key will no longer be accepted.

--quiet

Only print the unlock key, without instructions.
