How to remove default example dags in airflow

I am a new user of Airbnb's open source workflow/datapipeline software airflow. There are dozens of default example dags after the web UI is started. I tried many ways to remove these dags, but I've failed to do so.

• load_examples = False is set in airflow.cfg.
• Folder lib/python2.7/site-packages/airflow/example_dags is removed.

States of those example dags are changed to gray after I removed the dags folder, but the items still occupy the web UI screen. And a new dag folder is specified in airflow.cfg as dags_folder = /mnt/dag/1. I checked this dag folder, nothing is there. It's really weird to me why it is so difficult to remove these examples.

When you startup airflow, make sure you set:

load_examples = False

inside your airflow.cfg

If you have already started airflow with this not set to false, you can set it to false and run airflow resetdb in the cli (!which will destroy all current dag information!).

Alternatively you can go into the airflow_db and manually delete those entries from the dag table.

For Airflow 2.0, in docker-compose.yaml you can set AIRFLOW__CORE__LOAD_EXAMPLES: 'false' to not load them instead of editing the .cfg file.

Like others have said, you can change load_examples = False within airflow.cfg. However this requires that the cfg file already existing.

You can init the airflow DB without having to configure the cfg file by using ENV variables.

export AIRFLOW__CORE__LOAD_EXAMPLES=False
airflow initdb
