How to Test

Published the new KuboCD package version on a private registry, then triggered a new release with kubectl apply -f releases/airflow.yaml:

---
apiVersion: kubocd.kubotal.io/v1alpha1
kind: Release
metadata:
  name: airflow-patch
  namespace: default
spec:
  description: Airflow test patch
  package:
    repository: <my-registry>/kubodoc/packages/airflow
    tag: 3.2.1-p2
    interval: 30m
    insecure: true

This deployment does not trigger any errors:
