Spark 3 pod template for the driver

[Michel Sumbul]

Hi guys,

I try to use Spark 3 on top of Kubernetes and to specify a pod template for
the driver.

Here is my pod manifest or the driver and when I do a spark-submit with the
option:
--conf
spark.kubernetes.driver.podTemplateFile=/data/k8s/podtemplate_driver3.yaml

I got the error message that I need to specify an image, but it's the
manifest.
Does my manifest file is wrong, How should it look like?

Thanks for your help,
Michel
