+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.

+# CI Builder
+
+My CI testing pipeline for a django project.
+
+[![pipeline status](https://gitlab.ducoterra.net/ducoterra/ci_builder/badges/master/pipeline.svg)](https://gitlab.ducoterra.net/ducoterra/ci_builder/-/commits/master)
+
+## Prereqs
+
+1. Docker: https://www.docker.com/products/docker-desktop
+2. kubectl: https://kubernetes.io/docs/tasks/tools/#kubectl
+3. helm: https://helm.sh/docs/intro/install/
+4. k3d: https://k3d.io/
+5. You'll be using "*.localhost" domains for testing. This means you'll either have to use Chrome (which has these built in) or firefox. In Firefox:
+
+    1. Type `about:config` in the url field of your browser and press enter
+    2. Search for `network.dns.localDomains`
+    3. Double click to edit the field
+    4. Add these values: `button.localhost, pgadmin.localhost, traefik.localhost`
+    5. As you build your own sites you can add more to test!
+
+## Docker
+
+```bash
+# build the docker image. This uses the build step from docker-compose.yml.
+docker compose build
+
+# Now start postgres, pgadmin and traefik
+docker compose up -d postgres pgadmin traefik
+
+# Navigate to http://traefik.localhost to see your ingress routes
+
+# View the logs to check the container status
+docker compose logs
+
+# Now start the init container and wait for migrations to apply
+docker compose up init
+
+# Now start the button container
+docker compose up -d button
+
+# View the site logs
+docker compose logs --follow button
+
+# Navigate to http://button.localhost
+
+# Take down the site
+docker compose down
+```
+
+## K3D
+
+```bash
+# Create a cluster for our button app
+k3d cluster create button -p "80:8000@loadbalancer" --volume $HOME/.kube/registries.yaml:/var/lib/rancher/k3s/registries.yaml
