How do I clean up unused Docker volumes?

What does the command 'docker volume prune' do?

The 'docker volume prune' command removes all unused Docker volumes, freeing up space.

Are there any risks associated with using this command?

Yes, it will delete all volumes not currently in use by a container, so ensure you don't need them.

How can I see which volumes will be removed before I run the command?

You can use 'docker volume ls' to list all volumes and check which ones are unused before pruning.

Can I undo the prune operation if I accidentally delete something important?

No, once a volume is pruned, it cannot be recovered. Always double-check before running the command.
