I set up a local Kubernetes cluster using Kind, and then I run Apache-Airflow on it using Helm. 4 days ago. To actually create the pods and run Airflow, I use the command: helm upgrade -f k8s/values.yaml airflow bitnami/airflow which uses the chart airflow from the bitnami/airflow repo, and "feeds" it with the configuration of values.yaml. While Docker is at the heart of the containerization, it enables us to have containers in the first place. The platform ships with a user-friendly console to view and manage all your clusters so you have enhanced visibility across multiple deployments.
