Kustomizable

A curated collection of components meant to be built/modified using kustomize and applied to Kubernetes clusters.

Project Principles

Base kustomizations should:
- Define a ConfigMap in the kustomization.yaml to configure the application.
- Implement generic best-practices like:
  - {liveness,readiness} probes.
  - Prometheus scrape annotations.
- Reference secrets by name, leaving their implementation to the user.
- Be small, as in deployable to a default minikube cluster.
  - 1 replica where applicable.
- Use emptyDir volumes where persistent storage is expected.
  - Storage is domain-specific and should be kustomized by the user.
Overlay kustomizations should:
- Represent the most common modifications of a base (highly-available replicas, etc)
- Serve as examples for user overlays.
Bootstrap jobs should:
- Performs a one-time task.
- Generates resources that shouldn't be in version control (secrets).
- Generates resources with names that base kustomizations refer to.
