I have freshly installed airflow. I am getting this error when I am running webserver.
[2021-03-11 02:19:26,889] {dagbag.py:448} INFO - Filling up the DagBag from /dev/null
[2021-03-11 02:19:27,040] {manager.py:727} WARNING - No user yet created, use flask fab command to do it.
Why is DagBag being filled form /dev/null? I have correct location in .cfg file. What can I do/improve?
1 Did you setup AIRFLOW_HOME? The default value for dags_folder is {AIRFLOW_HOME}/dags
2 User isn't created by default. You will need to create a user to login.
create an admin user
airflow users create \
--username admin \
--firstname Peter \
--lastname Parker \
--role Admin \
--email spiderman@superhero.org
You can read more about this is the documentation.
I found the cause of the error web server not starting. When connecting postgresSQL, because the resource of docker ran out of memory to run airflow. So I solved it by increasing the memory to 4GB.
