Great work on having this guide in place. Have some minor suggestions/questions inline.

Should we also log a follow-up ticket for guiding on how to deploy to Astro deployment & how to create an Airflow connection there with mounting/using the needed Kubeconfig file?

LGTM. Tested the make docker-run command & was able to successfully spin up & run a DAG.
One question for the Dockerfile and some minor nits inline.
