The command 'docker volume ls' is designed specifically to list all Docker volumes available on the host system. Docker volumes are used for persisting data generated by and used by Docker containers, allowing this data to exist independent of the lifecycle of the container itself.

When you execute this command, it outputs a list that includes the names of the volumes and their associated driver information. This is useful for managing and inspecting what data storage solutions are in use, especially in scenarios where containers might be recreated or destroyed.

In contrast, other commands like those implied by the other choices serve different purposes. For instance, to view container configurations or logs, other specific commands would need to be utilized, such as 'docker ps' for viewing container statuses or 'docker logs' for log output from a container.
