I've created a public repo with some work to deploy an airflow docker image onto a local minikube environment (for development) and one to eventually deploy onto google cloud platform.
on GCP, it's using the deployment manager to work with simple templates and some dependency controls. it creates its own network and firewall rules and can be configured to put this into other zones and regions. The K8S deployment is still in active development and doesn't work 100% as I'm running into some database and user issues. Some of the deployment code is also commented. https://github.com/gtoonstra/airflow-deployments Hopefully it will be of use to someone. Rgds, Gerard
