How to add new DAGs to Airflow?

I have defined a DAG in a file called tutorial_2.py (actually a copy of the tutorial.py provided in the airflow tutorial, except with the dag_id changed to tutorial_2).

When I look inside my default, unmodified airflow.cfg (located in ~/airflow), I see that dags_folder is set to /home/alex/airflow/dags.

I do cd /home/alex/airflow; mkdir dags; cd dags; cp [...]/tutorial_2.py tutorial_2.py. Now I have a dags folder matching the path set in airflow.cfg , containing the tutorial_2.py file I created earlier.

However, when I run airflow list_dags, I only get the names corresponding with the default, tutorial DAGs.

I would like to have tutorial_2 show up in my DAG list, so that I can begin interacting with. Neither python tutorial_2.py nor airflow resetdb have caused it to appear in the list.

How do I remedy this?

I might be using the latest airflow, the command has changed. What works for me is:

  • export AIRFLOW_HOME="~/airflow"
  • Then run airflow dags list

The issue is that you might have two airflow configs existing in your directories, so check for /root/airflow/dags and if yes you require to change the dags_folder path in both airflow.cfg s
