+# Basic Airflow cluster configuration for CeleryExecutor with Redis and PostgreSQL.
+#
+# WARNING: This configuration is for local development. Do not use it in a production deployment.
+#
+# This configuration supports basic configuration using environment variables or an .env file
+# The following variables are supported:
+#
+# AIRFLOW_IMAGE_NAME           - Docker image name used to run Airflow.
+#                                Default: apache/airflow:2.8.3
+# AIRFLOW_UID                  - User ID in Airflow containers
+#                                Default: 50000
+# AIRFLOW_PROJ_DIR             - Base path to which all the files will be volumed.
+#                                Default: .
+# Those configurations are useful mostly in case of standalone testing/running Airflow in test/try-out mode
+#
+# _AIRFLOW_WWW_USER_USERNAME   - Username for the administrator account (if requested).
+#                                Default: airflow
+# _AIRFLOW_WWW_USER_PASSWORD   - Password for the administrator account (if requested).
+#                                Default: airflow
+# _PIP_ADDITIONAL_REQUIREMENTS - Additional PIP requirements to add when starting all containers.
+#                                Use this option ONLY for quick checks. Installing requirements at container
+#                                startup is done EVERY TIME the service is started.
+#                                A better way is to build a custom image or extend the official image
+#                                as described in https://airflow.apache.org/docs/docker-stack/build.html.
+#                                Default: ''
+#
+# Feel free to modify this file to suit your needs.
