[jira] [Commented] (SPARK-25742) Is there a way to pass the Azure blob storage credentials to the spark for k8s init-container?

Yinan Li commented on SPARK-25742:
----------------------------------

The k8s secrets you add through the {{spark.kubernetes.driver.secrets.}} config option will also get mounted into the init-container in the driver pod. You can use that to pass credential for pulling dependencies into the driver init-container.

> I'm trying to run spark on a kubernetes cluster in Azure. The idea is to store the Spark application jars and dependencies in a container in Azure Blob Storage.
> I've tried to do this with a public container and this works OK, but when having a private Blob Storage container, the spark-init init container doesn't download the jars.
> The equivalent in AWS S3 is as simple as adding the key_id and secret as environment variables, but I don't see how to do this for Azure Blob Storage.
