Minimal AWS IAM Policy for Packer

If we are working on a restricted or secure AWS environment and we need to use Packer, we can create a custom IAM policy for EC2 instances with the minimal permissions required:

  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "ec2:AttachVolume",
        "ec2:AuthorizeSecurityGroupIngress",
        "ec2:CopyImage",
        "ec2:CreateImage"…
