How to remove default example dags in airflow

问题

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.

回答1:

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.
