![]() ![]() The following sample job is adapted from documentation provided in Apache Spark to submit spark jobs directly to a Kubernetes cluster. Then submit the given jobs to the cluster in a container based off this image by using KubernetesPodOperator. Scale quite well (vertical scaling) and can be used in production. ![]() Backward compatibility of the APIs is not guaranteed for alpha releases. LocalExecutor which runs multiple subprocesses to execute your tasks concurrently on the same host. Project Status Alpha The Airflow Operator is still under active development and has not been extensively tested in production environment. Recommended for debugging and testing only. airflow AIP-49 Add support for OTel Gauges ( 31725) J20:50 chart Cleanup Kubernetes < 1.23 support ( 31847) J21:59 clients Update content type validation regexp for go client ( 29476) Febru18:03 constraints Remove Python 3. The worker and operator pods all run fine, but Airflow has trouble adopting the status.phase:'Completed' pods. The Executor starts Worker Pods, which in turn start Pods with our data-transformation logic. Rather build a Docker image containing Apache Spark with Kubernetes backend.Īn example Dockerfile is provided in the project. Apache Airflow gives you 5 type of executors: SequentialExecutor which is the most simple one to execute your tasks in a sequential manner. Our Airflow instance is deployed using the Kubernetes Executor. The cool thing about this Operator will be that you can define custom Docker images per task. You don't need to create Master and Worker pods directly in Airflow. How to best run Apache Airflow tasks on a Kubernetes cluster Ask Question Asked 4 years, 11 months ago Modified 4 years, 7 months ago Viewed 3k times 15 What we want to achieve: We would like to use Airflow to manage our machine learning and data pipeline while using Kubernetes to manage the resources and schedule the jobs. In the next release of Airflow (1.10), a new Operator will be introduced that leads to a better, native integration of Airflow with Kubernetes. As illustrated, a DAG is a series of tasks, and there are three common types of tasks in Airflow: Operators: Predefined tasks that you can use to execute. It delivers a driver that is capable of starting executors in pods to run jobs. The approach I'm attempting right now is to use KubernetesPodOperators to create Spark Master and Worker pods.Īpache Spark provides working support for executing jobs in a Kubernetes cluster. ![]()
