How can I use AWS IAM instance role with this package?

[v-kumar]

We don't use security credentials and instead use IAM instance roles for authorizing the instances to access S3 resources in EC2. How can I use this package, but using iam_role?

This functionality is not quite conveniently implemented yet. You'll either need to pass instance metadata to every call (see, for example, aws.ec2metadata) or, better, you can grab the development version of aws.signature which will look there automatically if security credentials aren't provided (but you'll have to pass explicit NULL values to the aws.s3 functions as the newest version of aws.signature relies on slightly different default argument values.

This has been configured as of https://github.com/cloudyr/aws.s3/commit/9627d8fe415ab9b293a02256a7e1e7645bd40052. You'll just need to have the aws.ec2metadata package installed to be able to use those credentials, but you shouldn't have to change any other code.
