## High Level Design
1. Manage the tftp directory
* /tftpboot/(coreos)(centos)(RHEL)
* /tftpboot/pxelinux.0/(MAC) -> linked to linux image config file
* /tftpboot/pxelinux.0/(MAC) -> linked to Linux image config file
2. Update per install the link for pxelinux
3. Update the DHCP config to reflect the host needing deployment
4. Setup nodes to deploy CoreOS creating a etcd cluster.
5. No have access to the public [etcd discovery tool](https://discovery.etcd.io/).

Now you should have a working PXELINUX setup to image CoreOS nodes. You can verify the services by using VirtualBox locally or with bare metal servers.
## Adding CoreOS to PXE
This section decribes how to setup the CoreOS images to live alongside a pre-existing PXELINUX environment.

1. Find or create the TFTP root directory that everything will be based off of.

2. Once we know and have our tftp root directory we will create a new directory structure for our CoreOS images.
3. Download the CoreOS PXE files provided by the CoreOS team.

## Specify the pxelinux targets
Now that we have our new targets setup for master and slave we want to configure the specific hosts to those targets. We will do this by using the pxelinux mechanisum of setting a specific MAC addresses to a specific pxelinix.cfg file.

## Creating test pod
Now that the CoreOS with Kubernetes installed is up and running lets spin up some Kubernetes pods to demonstrate the system.
Here is a fork where you can do a full walkthrough by using [Kubernetes docs](https://github.com/GoogleCloudPlatform/kubernetes/tree/master/examples/walkthrough), or use the following example for a quick test.
