Apache Spark™ K8s Operator is a subproject of [Apache Spark](https://spark.apache.org/) and
aims to extend K8s resource manager to manage Apache Spark applications via
[Operator Pattern](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/).
## Building Spark K8s Operator
Spark K8s Operator is built using Gradle.
To build, run:
```bash
$ ./gradlew build -x test
```
## Running Tests
```bash
$ ./gradlew build
```
## Build Docker Image
```bash
$ ./gradlew buildDockerImage
```
## Install Helm Chart
```bash
$ ./gradlew spark-operator-api:relocateGeneratedCRD
$ helm install spark-kubernetes-operator --create-namespace -f build-tools/helm/spark-kubernetes-operator/values.yaml build-tools/helm/spark-kubernetes-operator/
```
## Run Spark Pi App
```bash
$ kubectl apply -f examples/pi.yaml
$ kubectl get sparkapp
NAME CURRENT STATE AGE
pi ResourceReleased 4m10s
$ kubectl delete sparkapp/pi
```
## Run Spark Cluster
```bash
$ kubectl apply -f examples/prod-cluster-with-three-workers.yaml
$ kubectl get sparkcluster
NAME CURRENT STATE AGE
prod RunningHealthy 10s
$ kubectl port-forward prod-master-0 6066 &
$ ./examples/submit-pi-to-prod.sh
{
"action" : "CreateSubmissionResponse",
"message" : "Driver successfully submitted as driver-20240821181327-0000",
"serverSparkVersion" : "4.0.0-preview2",
"submissionId" : "driver-20240821181327-0000",
"success" : true
}
$ curl http://localhost:6066/v1/submissions/status/driver-20240821181327-0000/
{
"action" : "SubmissionStatusResponse",

}
$ kubectl delete sparkcluster prod
sparkcluster.spark.apache.org "prod" deleted
```
## Run Spark Pi App on Apache YuniKorn scheduler
```bash
$ helm install yunikorn yunikorn/yunikorn --namespace yunikorn --version 1.5.2 --create-namespace --set embedAdmissionController=false
$ kubectl apply -f examples/pi-on-yunikorn.yaml
$ kubectl describe pod pi-on-yunikorn-0-driver
...
Events:

```
## Try nightly build for testing
As of now, you can try `spark-kubernetes-operator` nightly version in the following way.
```
$ helm install spark-kubernetes-operator \
https://nightlies.apache.org/spark/charts/spark-kubernetes-operator-0.1.0-SNAPSHOT.tgz
```
## Clean Up
Check the existing Spark applications and clusters. If exists, delete them.
```
$ kubectl get sparkapp
No resources found in default namespace.
$ kubectl get sparkcluster
No resources found in default namespace.
```
Remove HelmChart and CRDs.
```
$ helm uninstall spark-kubernetes-operator
$ kubectl delete crd sparkapplications.spark.apache.org
$ kubectl delete crd sparkclusters.spark.apache.org
```
In case of nightly builds, remove the snapshot image.
```
$ docker rmi apache/spark-kubernetes-operator:main-snapshot
```
