If you don't have minikube installed, please run ./minikube/start_minikube.sh to start a k8s-instance on your local machine. Make sure that your kubectl is pointing to the local k8s instance.
First build the docker images by running ./docker/build.sh. This will build the image and push it to the local registry. Secondly, deploy Apache Airflow using ./kube/deploy.sh -d persistent_mode. Finally, open the Airflow webserver page by browsing to http://192.168.99.100:30809/admin/ (on OSX).
When kicking of a new job, you should be able to see new pods being kicked off:
