Database initialization

By default, Airflow will run database initialization routines (checking and/or creating the metadata schema and creating an admin user) on start-up. These are idempotent and can be run every time as the overhead is minimal. However, if these steps should be skipped, a running Airflow cluster can be patched with a resource like this to deactivate the initialization:

---
apiVersion: airflow.stackable.tech/v1alpha1
kind: AirflowCluster
metadata:
  name: airflow
spec:
  clusterConfig:
    dbInit: false  # (1)

  1. Turn off the initialization routine by setting dbInit to false

Note
 The field dbInit is true by default to be backwards-compatible. A fresh Airflow cluster cannot be created with this field set to false as this results in missing metadata in the Airflow database.
