Airflow DAG Multiple Runs

Question

I have a DAG that I want to run multiple times after each successful completion. For an example I want to run it 10 times and stop. Is there a way to accomplish this? I tried looking into scheduling with CRON but it doesn't seem clean nor triggering the DAG via UI multiple times doesn't work (runs in parallel).

Answer 1

I found a solution to my use case. It incorporated using depends_on_past=True (mentioned by @Hitesh Gupta) and setting your airflow.cfg file below:

# The maximum number of active DAG runs per DAG max_active_runs_per_dag = 1

This allowed us to only have one active DAG run at a time and also to not continue the next DAG run if there were failure in the previous run. This is for Airflow version 1.10.1 that I tested on.
