V4 signing support for ec2

[ekle]

added v4 signing for ec2

[bgentry]

As mentioned in #120, all AWS regions support v4 signatures http://docs.aws.amazon.com/general/latest/gr/sigv4_support.html

http://bazaar.launchpad.net/~goamz/goamz/trunk/revision/49 is the upstream commit adding the feature

[ekle]

i tried http://bazaar.launchpad.net/~goamz/goamz/trunk/revision/49 but it is not working here.
neither cn-north-1 nor eu-central-1.
The error is in both cases: The request must contain the parameter AWSAccessKeyId (MissingParameter)

+1 What ekie said. We need this for it to work in eu-central-1.

i don't know what to do, to get this pull request merged.
i'm using it in production for weeks now, and it works fine...

[madebyherzblut]

Any news on this pull request?

I'm also desperate to see this fixed as I need eu-central-1 support for Packer (mitchellh/packer#1646).

I'm assuming the hold up and this PR seemingly being ignored is that Packer, like Terraform, will probably switch to the official aws-sdk-go (mitchellh/packer#2034).

+1, better to switch to the official aws-sdk-go

[vedit]

Compiling using this branch solves the problems

[henrysher]

@vedit as packer has switched to aws-sdk-go, so i guess this goamz will not be maintained here.
