A docker container for running Synology's Virtual DSM.

Docker Hub: [kroese/virtual-dsm](https://hub.docker.com/r/kroese/virtual-dsm/)

## Prerequisites

In order to use the container, you need two images called `boot.img` and `sys.img` from Synology containing the Virtual DSM 7 OS. 

Place them in the `/home/user/images` folder. A third empty image, called `data.img` will be automaticly generated with a size of 16GB. If you need more space for your DSM instance, you can manually generate a larger file by running `truncate -s 100G data.img` from your host OS.

## Using the container

Via `docker run`:

        restart: always

```
