Support for credential_source in shared config

[haines]

I'd like to use credential_source in shared config files, but it doesn't seem to be supported by this sdk yet. Could I put in a feature request please?

Thanks!

#2201 got merged which adds support for credential_source

Thanks @hoshsadiq!

As @hoshsadiq already mentioned, #2201 now supports credential_source. Please let us know if there are any issues or questions with #2201.

So, I just implemented an ECS cluster that runs with terraform that uses the AWS go sdk, I have the following config:
~/.aws/config

[profile mosecurity-production]
region=us-east-1
output=json
role_arn=arn:aws:iam::12345678:role/Deployment
credential_source=EcsContainer

[profile mo-production]
region=us-east-1
output=json
source_profile=mosecurity-production
role_arn=arn:aws:iam::123456:role/Deployment

I recreated the environment on the EC2 instance and it works the confif is the following
~/.aws/config

[profile mosecurity-production]
region=us-east-1
output=json
role_arn=arn:aws:iam::12345678:role/Deployment
credential_source=Ec2InstanceMetadata

[profile mo-production]
region=us-east-1
output=json
source_profile=mosecurity-production
role_arn=arn:aws:iam::123456:role/Deployment
