The command to rotate a Docker swarm unlock-key is indeed "docker swarm unlock-key --rotate." This command is specifically designed for the purpose of changing the unlock key associated with a Docker swarm cluster.

When you rotate the unlock key, it enhances the security management of the swarm by ensuring that only the most recent key is valid for unlocking the swarm data. This is particularly important in a production environment, where managing access and permissions helps prevent unauthorized access to your swarm and its sensitive data.

The presence of the "--rotate" flag indicates that this action is about changing or rotating the key, as opposed to simply retrieving or displaying the current unlock key. This command is essential for maintaining the security posture of Docker swarm clusters, allowing administrators to manage their keys effectively and mitigate potential risks associated with key exposure or compromise.
