We have several python scripts that our team usually executes locally in their machines. We want them to move them to AWS for security reasons. These are ETL scripts.

We considered Lambda, but that would require refactoring.
So we thought the quickest way is to dockerize the scripts and execute them on ECS.

ECS Scheduled Tasks seems perfect but the schedule seems to be required. And we have scripts that we only want to schedule after an event. Is there a way to do this without a schedule?

Or any alternative recommendations to approach this?
