Kubeflow Spark Operator

Integration Test Go Report Card GitHub release

What is Spark Operator?

The Kubernetes Operator for Apache Spark aims to make specifying and running Spark applications as easy and idiomatic as running other workloads on Kubernetes. It uses Kubernetes custom resources for specifying, running, and surfacing status of Spark applications.

Quick Start

For a more detailed guide, please refer to the Getting Started guide.

# Add the Helm repository
helm repo add spark-operator https://kubeflow.github.io/spark-operator
helm repo update

# Install the operator into the spark-operator namespace and wait for deployments to be ready
helm install spark-operator spark-operator/spark-operator \
    --namespace spark-operator --create-namespace --wait

# Create an example application in the default namespace
kubectl apply -f https://raw.githubusercontent.com/kubeflow/spark-operator/refs/heads/master/examples/spark-pi.yaml

# Get the status of the application
kubectl get sparkapp spark-pi

Overview

For a complete reference of the custom resource definitions, please refer to the API Definition. For details on its design, please refer to the Architecture. It requires Spark 2.3 and above that supports Kubernetes as a native scheduler backend.

The Kubernetes Operator for Apache Spark currently supports the following list of features:

Project Status

Project status: beta

Current API version: v1beta2

If you are currently using the v1beta1 version of the APIs in your manifests, please update them to use the v1beta2 version by changing apiVersion: "sparkoperator.k8s.io/<version>" to apiVersion: "sparkoperator.k8s.io/v1beta2". You will also need to delete the previous version of the CustomResourceDefinitions named sparkapplications.sparkoperator.k8s.io and scheduledsparkapplications.sparkoperator.k8s.io, and replace them with the v1beta2 version either by installing the latest version of the operator or by running kubectl create -f config/crd/bases.
