Re: Airflow Docker Container
Great, I’m unfortunately unable to work on it today due to personal matters, but will check out the astronomerio Dockerfile asap. I think the Docker image should be a “basic” image and thus lightweight, i.e. just enough to get it started on K8S without any configuration.
I’ve forked the docker-library repos and got started on the docs. I’ll put them online tomorrow with a Dockerfile, so that we can get it checked by the docker library people.

As Scott pointed out, we at Astronomer.io<http://Astronomer.io> have taken the lightweight image philosophy to heart with our docker images. Our base image inherits from Alpine
(https://github.com/astronomerio/astronomer) and our Airflow image (https://github.com/astronomerio/astronomer/blob/master/docker/platform/airflow/Dockerfile) layers on that. We then have another layer (https://github.com/astronomerio/astronomer/blob/master/docker/platform/airflow/onbuild/Dockerfile) which can be used to install system level packages and python dependencies from packages.txt and requirements.txt.
If, for some reason, these images don't check all your boxes, let us know and we'll see what we can do to make them better for you.

You may consider this base image we put together at Blue Apron. My fork
