What Is using my Disk Space in var/lib/docker/overlay2?


#1

Hello,
I just moved a few small sites from Runcloud over to EasyEngine on a new Root Server.
Im quite impressed, its just working awesome.

But I got a Problem with the used disk space. On the old VPS the sites used about 8 GB, here on the new Server with EE it was using about 9 GB when I uploaded them. So far everything is fine, but now 2-3 days later my disk usage went up to 17 GB.

With ncpu I found out that 14,9/17Gb are located here: var/lib/docker/overlay2, which includes the following folders:
942.9 MiB [##########] /193a869b07615cf38a1973f7723b07386d4154c91c2d3638f5e9ab98120c0862
942.9 MiB [######### ] /5e84f06927823759b82096b150f0d0d12720558710f8dfcfe26ba57d0a4132f4
942.8 MiB [######### ] /bed142f2e359a8b0398247661516665ec10d045819158b2788b9b90ba627e388
[…] and a lot more of those. What are those folders for? Hope somebody can help me…

This might provide some guidance. The page is about a daily cron, but you can run the command manually:
