rsync

Simple rsync server running in a docker container

This is inspired by https://github.com/nabeken/docker-volume-container-rsync and https://github.com/bfosberry/rsync

Basic usage

Launch the container via docker:

docker run -d -p <port>:873 --name rsyncd mark86092/docker-rsyncd

You can connect to the rsync server you just created with:

rsync rsync://<docker>:<port>/
volume          volume

To sync:

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

Advanced

Some variables can be customized :

VOLUME

To set the name of the sync volume. Default is "volume"

Example :

docker run -d -p <port>:873 --name rsyncd \
              -e VOLUME="backup" \
              mark86092/docker-rsyncd

which will give :

rsync rsync://<docker>:<port>/
backup          backup

ALLOW

By 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 <port>:873 \
              --name rsyncd \
              -e ALLOW='10.0.0.0/8 x.x.x.x/y' \
              mark86092/docker-rsyncd

Sync volume

The sync folder exposed by rsyncd is a docker volume. You can map it to a local folder on the docker host : Example, if your docker host has a user "ubuntu" with id 1000 you can use :

docker run -d -p <port>:873 \
              --name rsyncd \
              -v /path/to/host/folder:/volume \
              mark86092/docker-rsyncd

Full example

docker run -d -p 873:873 \
              --name rsyncd \
              -e VOLUME="backup" \
              -v /srv/backup:/volume \
              mark86092/docker-rsyncd

This will start an rsync daemon, exposed on the standard port, with a volume named "backup", and map it to the host folder /srv/backup. Files created during sync will belong to user "ubuntu" and group "users" on a standard Ubuntu install.
