Docker Desktop completely kills my disk space (feddit.org)

Hi guys, I have no problem running docker (containers) via CLI, but I though it would be nice try Docker Desktop on my Ubuntu machine. But as soon as I start Docker Desktop it runs "starting Docker engine" indefinitely until my drive is full. The .docker folder then is about 70GB large. I read somewhere that this is the virtual disk size that is being created and that I could change it in the settings, but those are blocked until the engine starting process is finished (which it never does). Anyone else has experienced this?

Usually in my experience docker puts its images in /var/lib/docker. If your /var is on its own partition, or overall your disk space isn't big enough you'll have a bad time.

If you have other partitions with spare room, you can move the subdir docker from /var/lib to the other partition/drive, then symlink /var/lib/docker to that.
