# rsync
A simple rsync server that runs inside Docker. It is intended to be used as a volume and shared among containers where
A minimalist image with rsync daemon. It is intended to be used as a volume and shared among containers where
standard volume sharing results in poor read performance.
# Usage
The simplest use case is to run the image and map its 873 port:
```$ docker run stefda/rsync -p 873:873```
```bash
$ docker run stefda/rsync -p 873:873
```
The command above will spin up a container that listens on port 873 for rsync connections. To push files into the
container, you may use `rsync -rtR <file-or-directory> rsync://<docker-host-ip>:873/volume`.
The command above spins up a container that will listen on port 873 for connections over the native rsync protocol.
Syncing files is then as easy as `rsync -rtR <file-or-directory> rsync://<docker-host-ip>:873/volume`.
# Configuration
The module path, owning user, group and allowed hosts are all configurable via environmental variables. Launch fully
customised container like so:
```bash
$ docker run stefda/rsync -p 873:873 -e VOLUME=/my/volume -e USER=www-data -e GROUP=www-data -e ALLOW="192.168.0.0/16 10.0.0.0/16"
```
