Is it safe to delete files in /mnt/docker/overlay2?

Question

I am facing space issue in server due to docker overlay2 folder.It is taking space around 72GB.Many applications are running in this docker.Can I delete files which is in overlay2 folder?If I delete these files from overlay2 folder, any issues will occur in running containers? Please clarify. I have attached snapshot for reference.

It's better to run `docker system prune -af` so that let docker deletes everything unused — Saeed, Dec 30 '21 at 06:33

This question has already been answered: Is it safe to clean docker/overlay2/

If docker uses a huge amount of space I recommend the following command:

docker system prune --volumes

Use with caution!

docker system prune --help
