Those are images that are needed for the Helm Chart.

In each of the images you can find "build_and_push.sh" script that builds and pushes the image.

You need to be a PMC with direct push access to "apache/airflow" DockerHub registry to be able to push to the Airflow DockerHub registry.

You can set the DOCKERHUB_USER variable to push to your own DockerHub user if you want to test the image or build your own image.
