Is the s3 connection configurable with role arn alone?

Question

Alluxio on kubernetes(EKS) supports s3 connection without aws accessKey and secretKey? Is the s3 connection configurable with role arn alone? We are installing Alluxio on EKS using s3 as a underlaying storage layer. Alluxio cluster is up and running with s3 storage when configurations are done like below (Using aws aceess key and secret)

ALLUXIO_JAVA_OPTS: |--
Dalluxio.master.hostname=alluxio-master-0 -
Dalluxio.master.journal.type=UFS -
Dalluxio.master.journal.folder=/journal -
Dalluxio.security.stale.channel.purge.interval=365d -
Dalluxio.master.mount.table.root.ufs=s3://cubixalluxiodata/ -
Dalluxio.master.mount.table.root.option.aws.accessKeyId=AxxxxxxxxxxxxO -
Dalluxio.master.mount.table.root.option.aws.secretKey=DxxxxxxxxxxxxD*

However we are looking for approach to configure s3 storage for alluxio without accessKey/secretKey. But with a role arn based authentication alone. Please suggest on possibility of the approach.

looks to me you need to use AWS credential profile file (https://docs.alluxio.io/os/user/stable/en/ufs/S3.html#advanced-credentials-setup) to connect to S3. Possibly to setup your AWS instance profile file and share that file to your running image
