+# Kubernetes Development
+
+These configs and scripts attempt to simplify spinning up a kubernetes cluster
+for development and testing purposes. It leverages [k3d](https://k3d.io) to create
+a [k3s](https://k3s.io) cluster in Docker. Homepage can then be deployed either via
+the `k3d-deploy.sh` script, or [tilt](https://tilt.dev) 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.
+

+
+
+## One-off Test Deployments
+
+Create a cluster:
+
+```sh
+./k3d-up.sh
+```
+
+Build and deploy:
+
+```sh
+./k3d-deploy.sh
+```
+
+Open the Homepage deployment:
+
+```sh
+xdg-open http://homepage.k3d.localhost:8080/
+```
+
+## Continuous Deployment
+
+Create a cluster:
+
+```sh
+./k3d-up.sh
+```
+
+Kick off tilt:
+
+```sh
+tilt up
+```
+
+Press space bar to open the tilt web UI, which is quite informative.
+
+Open the Homepage deployment:
+
+```sh
+xdg-open http://homepage.k3d.localhost:8080/
+```
