I got an alert my docker image utilization is at 100%.  All of my dockers are configured to map folders to the cache disk.  I fired up CADvisor and all of my dockers disk usage doesn't add up anywhere near to the 20GB I have provisioned.   What else could be using all of the space?

 

 

 

 

 

 

 

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

I found the above command which tells me I have a 8.5 GB log somewhere in my docker:

8.5G /var/lib/docker/containers/651070b829a5e773eb905534612c7c3216f7b7003b93c50a35869b458a556002/651070b829a5e773eb905534612c7c3216f7b7003b93c50a35869b458a556002-json.log

 

I did a 'rm' to remove this log file.  Is this normal and will have to keep an eye out in the future?

Too bad you didn't "cat" the file first.  Then you would've been able to figure out which app was logging everything it did.  Either do the above to all the apps, or check each app's logging "level" within their UI and lower it if possible.

Thanks. I’m sure the log will spew again and I will check it out in a few days.
