I have tested it with duplicity, it seems that it can not use that instnace's role to get the bucket access. And with instance role you can generate some temporary access/secret key pairs but with additional token. Is there any way to use this in duplicity?

try to research if boto supports it. afaics duplicity simply utilizes boto, which handles auth itself via env vars or boto.cfg file.

same goes for why instance role does not work.

additionally you might ask your wuestion in mailing list

Thanks edso.

It seems that boto does support token parameter in its configuration file. But I still got "BackendException: No connection to backend" error when I put all those information into ~/.boto configuration.
