A volume container using rsync.

First, you can launch a volume container exposing a volume with rsync.

$ CID=$(docker run -d -p 10873:873 -v /tmp/:/data --name rsyncd metabrainz/docker-rsyncd)

You can connect to rsync server inside a container like this:

$ rsync rsync://<docker>:10873/
volume          docker volume

To sync:

$ rsync -avP /path/to/dir rsync://<docker>:10873/volume/

Next, you can launch a container connected with the volume under /data.

$ docker run -it --volumes-from $CID ubuntu /bin/sh

In default, rsync server accepts a connection only from 192.168.0.0/16 and 172.12.0.0/12 for security reasons. You can override via an environment variable like this:

$ docker run -d -p 10873:873 -e ALLOW='10.0.0.0/8 x.x.x.x/y' nabeken/docker-volume-container-rsync

• VOLUME - Define the volume path (default: /data)
• ALLOW - Which network segments to allow (default: 192.168.0.0/16 172.16.0.0/12)
• VOLUME_NAME - The logical name of the volume (default: volume)
• COMMENT - The share comment (default: docker volume)
• READ_ONLY - A boolean to set if the share should be read-only or not (default: true)
• OWNER/GROUP - Define the owner/group name or uid/gid to use (default: nobody/nogroup)
• BWLIMIT - Bandwidth limit in Kb/s (default: 0)
• MAX_CONNECTIONS - Maximum number of connections (default: 20)
