How can I clean up unused Docker images?

You can clean up unused Docker images by using the command docker image prune. This will remove all dangling images.

What if I want to remove all unused images, not just dangling ones?

In that case, you can use docker image prune -a. This command will remove all images that are not currently being used by any containers.

Is there a way to see which images will be removed before I run the command?

Yes, you can use docker images to list all images and then manually check which ones are unused before pruning.

Can I automate this cleanup process?

Absolutely! You can set up a cron job to run the prune command at regular intervals.
