Minimum IAM policy required by AWS for Packer to do its thing.
https://github.com/mitchellh/packer Permissions are broken out by API functionality and a resource array has been defined with a wild card for each group. For tighter security resource level permissions can be applied per this documentation: http://aws.typepad.com/aws/2013/07/resourc…

Missing ec2:ModifyInstanceAttribute
, which causes Packer to fail when enabling Enhanced Networking.
Missing ec2:DescribeSubnets
, needed for looking up Availability Zone when using a VPC subnet.
If you are creating a Windows image, you will also need ec2:GetPasswordData
.
Since packer supports spot instance now, you can add existing AWS role AmazonEC2SpotFleetRole
and permission ec2:CancelSpotInstanceRequests
to allow packer to use spot instance to build the AMI image.
There's a typo on line 34 - Snaphot instead of Snapshot
