I’m running syncthing in a Docker container (syncthing/syncthing) on OMV and after setting everything up it worked as expected.
But - after pulling a newer docker image from docker hub and/or restarting a container, the device ID for my OMV NAS is created new which means that I have to setup all shared folders on all connected devices again.
The config directory for docker syncthing is on a persistent path (not on a docker volume) and I thought that this means, that all configuration data is persistent as well. So - why do I get a new device ID when I restart the container or pull a new docker image?
What am I doing wrong?
It’s clearly not persisted, as it generates a new id on every startup.
This question is beyond syncthing, and you should seek for help with docker (use volumes).
Thanks for your answer Audrius!
But - the syncthing server does still know the shared folders and all other settings after pulling a new docker file or restarting the container. Why is a new device ID created and all other settings are the same as before the pull or the container restart?
Does anyone else have this behavior in docker syncthing?
No, I don’t see that problem with Docker. Post the commands you are using to run the container.
OK, I think I solved it. It seems to be related to OMV’s docker plugin. If I update the docker image or restart the container via the plugin, then it seems to create a new device ID. If I update it via this script:
docker pull syncthing/syncthing
docker stop syncthing
docker rm syncthing
docker run -d --name=syncthing --restart=always -e PUID=1000 -e PGID=100
-v /home/syncthing/config:/var/syncthing/config -v /srv/dev-disk-by-label-data:/var/syncthing
–network=syncthing -p 22000:22000 -p 8384:8384 syncthing/syncthing
… then the device ID stays the same …
User syncthing (uid 1000, gid 100) has access to /home/syncthing/config where the config files are stored persistently. The network “syncthing” is a bridged network that is used by syncthing only.
Thanks for your kind help!
