Apache Airflow Helm Chart 1.11.0

Significant Changes

Support naming customization on helm chart resources, some resources may be renamed during upgrade (#31066)

This is a new opt-in switch useStandardNaming, for backwards compatibility, to leverage the standard naming convention, which allows full use of fullnameOverride and nameOverride in all resources.

The following resources will be renamed using default of useStandardNaming=false when upgrading to 1.11.0 or a higher version.

• ConfigMap {release}-airflow-config to {release}-config
• Secret {release}-airflow-metadata to {release}-metadata
• Secret {release}-airflow-result-backend to {release}-result-backend
• Ingress {release}-airflow-ingress to {release}-ingress

For existing installations, all your resources will be recreated with a new name and Helm will delete the previous resources.

This won't delete existing PVCs for logs used by StatefulSet/Deployments, but it will recreate them with brand new PVCs.
If you do want to preserve logs history you'll need to manually copy the data of these volumes into the new volumes after
deployment. Depending on what storage backend/class you're using this procedure may vary. If you don't mind starting
with fresh logs/redis volumes, you can just delete the old PVCs that will be names, for example:

kubectl delete pvc -n airflow logs-gta-triggerer-0
kubectl delete pvc -n airflow logs-gta-worker-0
kubectl delete pvc -n airflow redis-db-gta-redis-0

If you do not change useStandardNaming or fullnameOverride after upgrade, you can proceed as usual and no unexpected behaviours will be presented.
