Docker critical image disk utilization


Recommended Posts

Hi experts,

it happens now the 4rd time, i got a notification from my server:

 

Docker critical image disk utilization: 16-03-2021 15:46

Alert [HORUS] - Docker image disk utilization of 100%
Docker utilization of image file /mnt/cache/docker.img

 

My docker.img has 10.485.760 kB and hosts only four dockers - three of them are stopped - so only plex is running.

After 1-2 min all went back to normal...

 

Docker image disk utilization: 16-03-2021 15:47

Notice [HORUS] - Docker image disk utilization returned to normal level
Docker utilization of image file /mnt/cache/docker.img

 

Can someone maybe explain, what happens in the background with my docker-system?
