Here are some simple steps to get things rolling using the Heat templates:

```
|

git clone https://github.com/larsks/heat-kubernetes/
|
||||
cd heat-kubernetes
|

```
|
||||
|

2. Create an appropriate image by running the get_image.sh script in this repository. This will generate an image called "fedora-20-k8s.qcow2". Upload this image to Glance. You can also obtain an appropriate image from

3. Create a file "local.yaml" with settings appropriate to your OpenStack environment. It should look something like:

server_image: fedora-20-k8s
|

ssh_key_name: sdake

a value for server_image, which should be the name (or UUID) of a Fedora 20
