Why can’t I see my dags?

With this Docker-Compose I run my local images on Windows.

The problem is that I cannot access local folders on my Ubuntu 18.04 to load the Dags. Here are my Dags on Ubuntu:

Here one can see that the Dags do not appear:

It’s as if my contents didn’t really "see" the local folder of Ubuntu. How do I do this?

Answer 1

1 - In the folder where your Docker-Compose file is, create a folder called Dags and place your Dags inside this folder.

2 - In Docker-Compose, in volumes, share the standard Airflow folder with local folder that contains your Dags:

Everything will work.
