Serverless CLI: How to configure the credentials including assuming another role?

[kastl-ars]

Hi all,

I would like to use the serverless CLI with a AWS account that needs to switch to a different role. I did not find any hints on how to do that or I have the wrong search terms :-) ).

My AWS CLI configuration file looks like this:

[default]
region = eu-west-1

[profile administrator]
role_arn = arn:aws:iam::xxx:role/yyy
source_profile = default

How would I get the serverless CLI to use something like the administrator profile?

I found this discussion, but I think provider.iam.deploymentRole does something different.
#11062

Thanks in advance!

Kind Regards,
Johannes
