certificatemanager:changeResourceRecordSets user is not authorized to access this resource

Question

Trying to create an SSL certificate using Amazon Certificate Manager, as per here -

https://medium.com/swlh/aws-website-hosting-with-cloudformation-guide-36cac151d1af

I have a deployment user with the following policy -

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "cloudformation:*",
                "s3:*",
                "route53:*",
                "acm:*"
            ],
            "Effect": "Allow",
            "Resource": "*"
        }
    ]
}

But when I deploy I get the following -

API: certificatemanager:changeResourceRecordSets User #{my_IAM_deploy_user} is not authorized to access this resource      

How come I am getting this error despite acm:* access?

(wondering if related to Why changeResourceRecordSets gets not authorized to access this resource? but can't see exactly how)

Answer 1

I misunderstood what HostedZoneId was. I thought it was some kind of route53 region- specific singleton but (doh) turns out it just the id of a route53 HostedZone I had created. Kinda obvious really.
