How to see how much disk space is being used by Docker

[LondonAppDev]

I was wondering if anyone can tell me how (if at all) you can check the disk usage status for allocated disk space?

So, if I run colima start --disk 20, how do I know how much of the 20GB allocated is being used?

colima ssh and df -h /usr/local

(Edited - before I gave an answer that would show the mounted disk, I think this will do)

@LondonAppDev you can run the command in one go.

colima ssh -- df -h /usr/local
