## Getting a Binary Release
You can either build a release from sources or download a pre-built release. If you don't plan on developing Kubernetes itself, we suggest a pre-built release.

There is a specific `cluster/rackspace` directory with the scripts for the following steps:
1. A cloud network will be created and all instances will be attached to this network.
- flanneld uses this network for next hop routing. These routes allow the containers running on each node to communicate with one another on this private network.
2. A SSH key will be created and uploaded if needed. This key must be used to ssh into the machines since we won't capture the password.

3. The master server and additional nodes will be created via the `nova` CLI. A `cloud-config.yaml` is generated and provided as user-data with the entire configuration for the systems.
4. We then boot as many nodes as defined via `$NUM_MINIONS`.
