Help with high docker utilization

[nathanj]

Im confused as to what is filing up my 100gb docker file.

 

Here are some outputs of commands, does anyone have any ideas that dont involve me deleting my docker file and starting from scratch?

You want to use

docker ps -s -a

 

By and large, there's only 2 reasons for the image filling up (btw, 100 Gig is way overkill)

 

- Excessive logging from an application

du -ah /var/lib/docker/containers/ | grep -v "/$" | sort -rh | head -60 | grep .log

 

or

 

- Inadvertently saving downloads, plex's config etc into the image (which it doesn't *appear* that it is)

 

You can delete any dangling images 

docker rmi $(docker images --quiet --filter "dangling=true")

If you can't find the reason, this is what you have to do.  And, its an extremely painless operation.  

- Stop the service, delete the image, restart the service, Apps tab, Previous apps, Check off your apps, hit reinstall.  2 minutes later you're back up and running with no changes required.
