Docker Container for Syncthing
Use the Dockerfile in this repo, or pull the
from Docker Hub.
/var/syncthing volume to have the synchronized files available on the
host. You can add more folders and map them as you prefer.
Note that Syncthing runs as UID 1000 and GID 1000 by default. These may be
altered with the
PGID environment variables.
$ docker pull syncthing/syncthing $ docker run -p 8384:8384 -p 22000:22000 \ -v /wherever/st-sync:/var/syncthing \ syncthing/syncthing:latest
Note that local device discovery will not work with the above command, resulting in poor local transfer rates if local device addresses are not manually configured.
To allow local discovery, the docker host network can be used instead:
$ docker pull syncthing/syncthing $ docker run --network=host \ -v /wherever/st-sync:/var/syncthing \ syncthing/syncthing:latest
Be aware that syncthing alone is now in control of what interfaces and ports it listens on. You can edit the syncthing configuration to change the defaults if there are conflicts.
By default Syncthing inside the Docker image listens on 0.0.0.0:8384 to
allow GUI connections via the Docker proxy. This is set by the
STGUIADDRESS environment variable in the Dockerfile, as it differs from
what Syncthing would otherwise use by default. This means you should set up
authentication in the GUI, like for any other externally reachable Syncthing
instance. If you do not require the GUI, or you use host networking, you can
STGUIADDRESS variable to have Syncthing fall back to listening
$ docker pull syncthing/syncthing $ docker run -e STGUIADDRESS= \ -v /wherever/st-sync:/var/syncthing \ syncthing/syncthing:latest
With the environment variable unset Syncthing will follow what is set in the configuration file / GUI settings dialog.
