Initial disk space usage
I did an ncdu report right after installing my personal cluster from scratch.
If shows an initial 17,3 GiB (!) in /var/lib/docker/overlay2/
. That's kind of insane.
-- / -------------------------------
17.3 GiB [##########] /var
1.4 GiB [ ] /usr
333.5 MiB [ ] /snap
97.3 MiB [ ] /lib
73.4 MiB [ ] /tmp
67.7 MiB [ ] /opt
67.2 MiB [ ] /root
46.1 MiB [ ] /oas
--- /var/lib/docker ------------------------
/..
16.2 GiB [##########] /overlay2
45.0 MiB [ ] /volumes
14.9 MiB [ ] /image
4.1 MiB [ ] /containers
104.0 KiB [ ] /network
56.0 KiB [ ] /buildkit
16.0 KiB [ ] /builder
I couldn't find a way out of the box how to display the details of this (what's taking how much space in docker?).
