This is a simple implementation of the KOReader (https://github.com/koreader/koreader) position sync server for self-hosting at home which has docker support for arm and amd64 :) This is a fork of https://github.com/myelsukov/koreader-sync but with a complete code rewrite.

• FastAPI : https://github.com/tiangolo/fastapi
• TinyDB: https://github.com/msiemens/tinydb
• Uvicorn: https://www.uvicorn.org/
• Python-dotenv: https://saurabh-kumar.com/python-dotenv/

> pip install -r requirements.txt
> uvicorn kosync:app --host 0.0.0.0 --port 8081

> docker build --rm=true --tag=kosync:latest .
> docker compose up -d

• RECEIVE_RANDOM_DEVICE_ID ("True"|"False")

Set it true to retrieve always a random device id to force a progress sync. This is usefull if you only sync your progress from one device and usually delete the *.sdr files with some cleaning tools.

• OPEN_REGISTRATIONS ("True"|"False")

Enable/disable new registrations to the server. Useful if you want to run a private server for a few users, although it doesn't necessarily improve security by itself. Set to True (enabled) by default.

There is also a dockerhub image available if you are not able to build yourself the image.

For linux/amd64 you can use docker pull b1n4ryj4n/koreader-sync and for linux/arm docker pull b1n4ryj4n/koreader-sync:arm

• Use http://IP:8081 as custom sync server
• Recommendation: Setup a reverse proxy for example with Nginx Proxy Manager (https://nginxproxymanager.com/) to connect with https

• Merged "Option to disable registration of new user accounts by env var."

• Added the HEALTHCHECK command (also accessible via http://IP:8081/healthstatus)

• Added an environment variable option to receive always a random device id

• Merged "Dockerfile: use multi-stage build to optimize image size"

• First version
