Docker compose file for airflow 2 ( version 2.0.0 )
Question:
I am looking to write docker compose file to locally execute airflow in production similar environent.
For older airflow v1.10.14, docker compose is working fine. But same docker compose is not working for latest stable version, airflow scheduler & webservice is failing continuously. error message looks like unable to create audit tables.
