trigger spark job from Airflow bitnami on compute engine

[joarodrigues]

Hi

I have successfuly deployed a job in airflow from google cloud composer.
I'm trying now to do the same by provisioning a VM in compute engine from the marker place with Apache Airflow Bitnami.
But i can't find any sample on how to connect this Airflow to my spark cluster on Dataproc.
Can someone help ?

Thanks
