The following code is my attempt at creating a SPA (Single Page Application) CloudFormation template. I understand there are probably many flaws but I can't conceptually understand how to break the circular dependency error I am getting. In my head, it only makes sense that Route53 depends on CloudFront because it needs to know the AliasTarget
, it also makes sense that CloudFront needs to depend on Certificate Manager because it needs AcmCertificateArn
and CertificateManager needs to depend on Route53 (for obvious reasons but I have a feeling someone is going to tell me this is where I break the chain).
