Hi! Can you create an image in docker hub? My server doesnt have docker compose built in and I tried using my laptop but it has a different architecture (ARM vs x86). :(

Hi,

I'm currently searching for an ereader app that supports OPDS as well progress syncing across devices. Koreader seems to offer both with the sync server and I've tried to spin up your image from docker hub using compose on my system.

This works fine and koreader can connect as well as push updates.

However, to backup the container state I would like to mount the database to a persistent volume through docker compose and backup this directory. But when I try to mount the "/app" directory, the container no longer starts with the following error

ERROR: Error loading ASGI app. Could not import module "kosync".

If I don't mount any volumes, the container works fine.

Could you modify the image so that it is possible to mount the database to a volume and have it backed up externally?

Someone on stackoverflow posted this as a solution for his app https://stackoverflow.com/a/71875029
Since in your image, "/app" is directly in the root of the container image, this doesn't work. Heres my compose snippet for your container:

# Koreader-Sync
  koreader-sync:
    image: b1n4ryj4n/koreader-sync:latest
    container_name: koreader-sync
    restart: unless-stopped
    security_opt:
      - no-new-privileges:true
    environment:
      UID: $PUID
      GID: $PGID
      TZ: $TZ  
    volumes:
      - $DOCKERDIR/koreader-sync:/app 

I really appreciate your work and I'd like to donate a (small) amount of money as a way to thank you. Do you have a buymeacoffee account or something similar?
