I am sure this is a silly question, but when I made this, I assumed all of my apps would live in here.  But I just installed plex and its config directory is \cache\.Docker\appdata\plex.

 

I assumed I would be specifying the IMG file.  Can someone clarify?

All of the applications itself live within the img file.  All of the metadata, downloads, media, databases, etc live outside the img file (in your case within /cache/.Docker/appdata/plex

So if I am only running a few apps, 10GB is probably way overkill....  Opps

 

Thanks for the clarification

That all depends on how frequently you update the apps or if the apps auto update. The space chews through rather quickly as sometimes even when you uninstall an app and image the remnants still remain. It is better to have too much than to not have enough and then run out of space, which will cause your dockers to fail.  That would force you to delete the entire image file and restart to rebuild/readd the docker containers again.

 

Keep an eye on how much space the container is using:

df -h /var/lib/docker
