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/linux-headers-3.11.0-17_3.11.0-17.28_all.deb            
sudo gdebi --n binary_dependencies/builder/linux-headers-3.11.0-17-generic_3.11.0-17.28_amd64.deb  
sudo gdebi --n binary_dependencies/builder/linux-image-3.11.0-17-generic_3.11.0-17.28_amd64.deb    
sudo gdebi --n binary_dependencies/builder/linux-image-extra-3.11.0-17-generic_3.11.0-17.28_amd64.deb
sudo gdebi --n binary_dependencies/builder/nsexec_1.22ubuntu1trusty1_amd64.deb
sudo gdebi --n binary_dependencies/builder/lxc-docker-0.8.0-tutum_0.8.0-tutum-20140212002736-afad5c0-dirty_amd64.deb
sudo chown -R 100000:100000 /var/lib/docker
sudo shutdown -r now
```

pull some base images if you want (optional)
```
sudo docker pull ubuntu
sudo docker pull stackbrew/ubuntu
sudo docker pull busybox
sudo docker pull lopter/raring-base
```

start the worker

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