to prepare a new build node host:

```
sudo apt-get update
sudo apt-get install -y git python-virtualenv python-dev phantomjs libjpeg8 libjpeg62-dev libfreetype6 libfreetype6-dev libevent-dev gdebi-core
```

check out the code, install the kernel, custom docker, nsexec, and reboot:

```
git clone https://bitbucket.org/yackob03/quay.git
cd quay
sudo gdebi --n binary_dependencies/builder/*.deb
sudo chown 100000:100000 /var/lib/docker
sudo shutdown -r now
```

start the worker

```
cd quay
virtualenv --distribute venv
source venv/bin/activate
pip install -r requirements.txt
STACK=prod python -m workers.dockerfilebuild -D
```
