credentials_process is unsupported

[dunindd]

I have an ~/.aws/credentials file with the following content:

[default]
credential_process = get-toke --role my-role
region = us-west-2

When running aws-es-proxy I expect the program to execute the credentials_process program to retrieve AWS credentials. However, it does not seem that this is supported. I also notice that there is a request to support multiple profiles for AWS (#34).

I was able to resolve my issue, and support multiple profiles by simply bumping the AWS SDK version.

$ git diff glide.yaml 
diff --git a/glide.yaml b/glide.yaml

This also allowed me to run to choose the profile I wanted to use with aws-es-proxy as follows:

ENV AWS_DEFAULT_PROFILE=my-profile aws-es-proxy ...
