Kustomize plugin showcase

DockerHub

Proves we could use containerized tools (like konfigure) to modify our kustomizations.

main.go, containerized as docker.io/wttyf00l/konfigure-plugin:latest, adds a ConfigMap in process of modifying existing app resources.

Requires kustomize v4

Usage:

docker build -t docker.io/wttyf00l/konfigure-plugin:latest .
kustomize build --enable-alpha-plugins app/

Expected output:

apiVersion: v1
data:
  registry: docker.io
  ttl: 24h
kind: ConfigMap

  creationTimestamp: null
  name: from-plugin
