Hi all! I'm looking for a best practice to deal with custom domains (APIs and static sites) while having an AWS account per stage. So basically my

dev

and

prod

stages both have their own AWS account. Now, if I want my dev domain to be

<http://dev.domain.com|dev.domain.com>

and my prod domain to be

<http://www.domain.com|www.domain.com>

, what would be the best approach? From the guide:

Of course, you can change this if you’d like to use a custom domain for the other stages. You can use something like
${scope.stage}.<http://my-serverless-app.com|my-serverless-app.com>
. So for
dev
it’ll be
<http://dev.my-serverless-app.com|dev.my-serverless-app.com>
. But we’ll leave this as an exercise for you.

Should I just register the domain in the

prod

account and manually set the certificates for

dev

Hi Dimitri, I would use DNS delegation to delegate the subdomain

<http://dev.domain.com|dev.domain.com>

to the account use use for dev, that way the DNS and certificate creation can be handled automatically without any intervention. This should help you https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/CreatingNewSubdomain.html

Basically you are giving route53 in the dev account full control to manage the dns for the whole subdomain

<http://dev.domain.com|dev.domain.com>

so your SST/CDK code will just work on the existing a-count you are on.

@Dimitri van Hees SST also has a chapter about this https://serverless-stack.com/chapters/share-route-53-domains-across-aws-accounts.html

@Dimitri van Hees you can just stop after setting up the Route53 hosted zone in your dev AWS account. Skip the SEED steps.

The overall setup looks likes: 1. Ensure the

<http://domain.com|domain.com>

already exists in ur

prod

account 2. Follow the tutorial to setup

<http://dev.domain.com|dev.domain.com>

HostedZone in ur

dev

account 3. In SST app, set up Api domain:

Copy code

new Api(this, "api", {
  customDomain: scope.stage === "prod"
    ? "<http://api.domain.com|api.domain.com>"
    : `<http://api.dev.domain.com|api.dev.domain.com>`,
  ...
});

4. Setup StaticSite domain:

Copy code

new StaticSite(this, "site", {
  customDomain: scope.stage === "prod"
    ? "<http://www.domain.com|www.domain.com>"
    : `<http://dev.domain.com|dev.domain.com>`,
  ...
});
