Hey guys,
I’m learning Docker, reading and watching a lot. For practising purposes, I have installed Docker and and docker-compose on my home server running Arch Linux.
The server is running ZFS from AUR (Arch User Repositories) version 0.7.9-1, kernel 4.16.13-1.
I’ve created a ZVOL for Bitwarden, since it contains MSQL Express that doesn’t run on ZFS and formatted it with EXT4. It is mounted to /data/bitwarden.
A regular ZFS dataset has been created for /var/lib/docker for Unifi and qbittorrent containers.
Docker info shows Storage driver: zfs is in use, parent dataset data/docker.
Logging driver is set to journald.
Last but not least, Docker Server Version: 18.05.0-ce.
Pacman lists docker and docker-compose installed as versions:
community/docker 1:18.05.0-2 [installed]
Pack, ship and run any application as a lightweight container
community/docker-compose 1.21.2-1 [installed]
I totally admit my knowledge is lacking, I’ve been trying to figure this out and read up about what is happening and how this is supposed to work, but I can’t find what is going wrong in my situation.
I hope someone here can help me figure this out and understand what is going on.
I’ve ran docker image/volume/network prune commands. First time it cleared up some left overs from containers I’ve ran but since deleted.
I understand the concept of the overlays, I’m pretty sure the mount list below is good but I included it for completeness sake. I can make no sense of the zfs filesystem list and the network list though. These are my main concerns, why do I have so many filesystems and network interfaces, while the docker volume/image and docker network commands show only what I actually have and use?
Apologies for the complete wall of text below.
Thanks for any help!
