Add an aws_creds function for COPY commands

👍
Another useful thing would be the option to get role-based credentials whenever available, and it seems the Golang SDK already has this implemented.

[alexanderdean]

Yes that would be nice...

Any ideas on how do you plan on doing it? I think I might be able to contribute something towards it in the next few days, since I'm gonna need it too.

The easiest way I see is to use the Golang SDK (which automatically gives us the support to reading the credentials from profiles, environment variables and roles), and then inject them as predefined variables (aws_access_key_id and aws_secret_access_key?) inside the playbook. Any objections to this approach?

[alexanderdean]

Using the Golang SDK sounds good. I think the two options are:

inject them as predefined variables (aws_access_key_id and aws_secret_access_key?) inside the playbook

or

\2. Create a template function aws_access_credentials which generates a string of the format:

'aws_access_key_id=<access-key-id>;aws_secret_access_key=<secret-access-key>'

This is because the only places I can think these creds would be useful are in COPY and UNLOAD statements, which use the above credentials syntax...

[andrioni]

Yes, indeed, and it avoids horribly overextending the meaning and creation methods of variables.

[alexanderdean]

Cool!
