How to define Airflow DAG/task that shouldn't run periodically

The goal is pretty simple: I need to create a DAG for a manual task that should not run periodically, but only when admin presses the "Run" button. Ideally without a need to switch "unpause" and "pause" the DAG (you know someone will surely forget to pause).

So far I only came with schedule_interval="0 0 30 2 *" (30th Feb hopefully never occurs), but there must be a better way!

Is there?

Solution

  • Based on the documentation, you can set the scheduler preset to None (Don’t schedule, use for exclusively “externally triggered” DAGs). Also, you can set it to @once if schedule once and only once.
