Running Spark job on local kubernetes (minikube)

spark-minikube.sh

# Starting minikube with 8Gb of memory and 3 CPUs
minikube --memory 8192 --cpus 3 start

# Creating separate Namespace for Spark driver and executor pods
kubectl create namespace spark

# Creating ServiceAccount and ClusterRoleBinding for Spark 
kubectl create serviceaccount spark-serviceaccount --namespace spark
kubectl create clusterrolebinding spark-rolebinding --clusterrole=edit --serviceaccount=spark:spark-serviceaccount --namespace=spark

# Spark home dir
cd $SPARK_HOME

# Asking local environment to use Docker daemon inside the Minikube
eval $(minikube docker-env)
# Building Docker image from provided Dockerfile
docker build -t spark:latest -f kubernetes/dockerfiles/spark/Dockerfile .

# Submitting SparkPi example job
# $KUBERNETES_MASTER can be taken from output of kubectl cluster-info
bin/spark-submit --master k8s://$KUBERNETES_MASTER --deploy-mode cluster --name spark-pi --class org.apache.spark.examples.SparkPi --conf spark.executor.instances=2 --conf spark.kubernetes.namespace=spark --conf spark.kubernetes.driver.pod.name=spark-pi-driver --conf spark.kubernetes.container.image=spark:latest --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark-serviceaccount local:///opt/spark/examples/jars/spark-examples_2.11-2.4.0.jar

# Printing Spark driver's log
kubectl logs spark-pi-driver --namespace spark

# When the application completes, the executor pods terminate and are cleaned up, 
# but the driver pod persists logs and remains in "completed" state.
# Deleting spark-pi-driver pod
kubectl delete pod spark-pi-driver --namespace spark

How to use SparkLauncher programmatically submit spark job to minikube? Any example is appreciated.
