How to list all VPC dependencies in AWS CLI

IAM Policies do not allow restriction of access to specific CloudFront distributions. The solution is to use a wildcard for the resource, instead of only referencing a specific CloudFront resource. Adding that to your IAM policy will fix the issue you're having.

Here is an example of that in a working IAM policy:

{
  "Statement": [  
    {
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "arn:aws:s3:::*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "cloudfront:CreateInvalidation",
        "cloudfront:GetInvalidation",
        "cloudfront:ListInvalidations"
      ],
      "Resource": "*"
    }
  ]
}

I couldn't find how to associate a VPC to a Route53 hosted zone, so I've added to the user_data script the following code:

aws route53 get-hosted-zone --id XXXAAA12345 | grep -q $vpcid
if [[ ! $? -eq 0 ]]; then
  aws route53 associate-vpc-with-hosted-zone --hosted-zone-id XXXAAA12345 --vpc VPCRegion=us-west-2,VPCId=$vpcid
else
  echo "VPC $vpcid is already associated to hosted zone company-private"
fi

vpcid variable is inherited from the CloudFormation template:

{ "Fn::Join": [ "=", [ "vpcid", { "Ref": "VPC" } ] ] },

Then, I realized that when a VPC is deleted, it's association to the Route53 hosted zone remains.

In order to make sure that old associations are removed, I've added the following code to the user_data script:

defaultvpc="vpc-20AAAA4b"
vpc_array=()
for vpc in $(aws route53 get-hosted-zone --id XXXAAA12345 | grep vpc | awk '{print $2}' | tr -d '\"|,'); do
  vpc_array+=($vpc)
done
for i in ${!vpc_array[@]}; do
  if [[ ! ${vpc_array[$i]} = $vpcid && ! ${vpc_array[$i]} = $defaultvpc ]] ; then
    echo "VPC ${vpc_array[$i]} doesnt exist anymore - removing association to Route53 hosted zone"
    aws route53 disassociate-vpc-from-hosted-zone --hosted-zone-id XXXAAA12345 --vpc VPCRegion=us-west-2,VPCId=${vpc_array[$i]}
  fi
done
