A minimalist image with rsync daemon. The intention is to run a rsync daemon on host with docker without the need of rsyncd setup (e.g. running on a NAS).
The benefit compare to transfer over SSH is the SPEED (avoid SSH overhead). From my testing can be at least 2x faster!
This has been published to windix/docker-rsyncd on docker-hub.
The simplest use case:
On server side, start rsyncd for current directory and map its 873 port (default rsyncd port):
$ docker run -p 873:873 -v $(pwd):/volume windix/docker-rsyncd
On client side, to transfer files over the native rsync protocol:
$ rsync -av --progress <file-or-directory> rsync://<docker-host-ip>:873/volume
To map with your host UID and GID to avoid permission issues, you can pass UID and GID environment variables correspondingly (default value is 1000 for both).
Also you can specify ALLOW for IP whitelist (default is 127.0.0.1 192.168.0.0/16 10.0.0.0/16)
Here is a more complicated example:
$ docker run -p 873:873 -e VOLUME=/incoming -e UID=1000 -e GID=100 -e ALLOW="127.0.0.1 192.168.0.0/16 10.0.0.0/16" -v /mnt/user/incoming:/incoming windix/docker-rsyncd
