Kubernetes Development

These configs and scripts attempt to simplify spinning up a kubernetes cluster for development and testing purposes. It leverages k3d to create a k3s cluster in Docker. Homepage can then be deployed either via the k3d-deploy.sh script, or tilt can be used to spin up a local CI loop that will automatically update the deployment.

All the commands in the document should be run from the k3d directory.
