Hi ,

Im wondering if there is a way to determine if the command "airflow initdb" ran ...

I know that this command should run only once when we initialize the Database , i want a generic command to be able to check if the command ran regardless of the backend that is used in airflow.cfg.

Currently im checking it via mysql query to see if a table exists , but what if we will change the backend to something else...

Thanks in Advance,

Costya.

Do you mean programmatically in Python? If so you could just wrap a generic sqlalchemy query in a try statement. If the table isn't there it will raise.

I want to have the ability to know if the user which ran the installation of Airflow for the first time ran the command "airflow initdb" if not i would like to run it myself via a configuration manager.

It's non destruction, so you can run it twice or as many times as you want.
