Mailcow Dockerized: Disk Cleanup

alexander

Only Mailcow Dockerized works on my server and takes up a lot of disk space:

/var/lib/docker/ -------------------------------------------------------------------------------------------------------------------------------------------------
    9.2 GiB [##########] /containers
    6.7 GiB [#######   ] /overlay2
    1.3 GiB [#         ] /volumes
   13.3 MiB [          ] /image
  160.0 KiB [          ] /network

I tried to clear the disk space through docker system prune, but it didn’t help:

sudo docker system prune -a

And which container consumes the most space?

esackbauer

Probably some log files taking up the space

@esackbauer mailcow/watchdog, mcuadros/ofelia and mailcow/postfix take up the most disk space

And? Did you check those folders under /containers what is using the space? The /overlay2 is pretty much the same size as with my installation.
And the minimum requirement per documentation is 20 GB plus mailbox storage
