Airflow Operator Overview

Airflow Operator is a custom Kubernetes operator that makes it easy to deploy and manage Apache Airflow on Kubernetes. Apache Airflow is a platform to programmatically author, schedule and monitor workflows. Using the Airflow Operator, an Airflow cluster is split into 2 parts represented by the AirflowBase and AirflowCluster custom resources. The Airflow Operator performs these jobs:

  • Creates and manages the necessary Kubernetes resources for an Airflow deployment.
  • Updates the corresponding Kubernetes resources when the AirflowBase or AirflowCluster specification changes.
  • Restores managed Kubernetes resources that are deleted.
  • Supports creation of Airflow schedulers with different Executors
  • Supports sharing of the AirflowBase across mulitple AirflowClusters
