How to automate flow flow build ?

I have multiple python scripts that i use to ingest data from DB and perform ETL steps .

At the moment all the ETL logic runs on an on premise server (mainly using python / cron).

Since we have Dataiku available since few things, i'm thinking about migrating all our ETL to Dataiku (flows using python recipes).

Yet , it is not clear how to automate python recipes execution ?
