Docker?

I started playing around with a Dockerfile...

```
$ docker run --rm -it \
    -v $PWD:/git \
    -v $HOME:/root \
    git-vanity-sha cafe
```

https://github.com/AnthonyMastrean/git-vanity-sha/commits/dockerfile

Is this interesting for anyone else? Can someone test this on Linux/Mac?
