Tell us about your request There is no CloudFormation support for creating custom domains for AWS App Runner. There should be a new resource created called something like AWS::AppRunner::CustomDomain. The related links included have the fields that need to be included.

This should support the creation of relevant constructs in the CDK (https://github.com/aws/aws-cdk/issues/19740)

Describe alternatives you've considered Fargate/ECS

On the CFN coverage roadmap, issue 1092 (referenced above) is showing as shipped, but issue 1146 seems to indicate that it's not actually shipped.

In other contexts, I've experienced features being shipped but not yet documented. It's unclear which situation we're in with this feature - clarifying that might be a good place to start.

There's a workaround using Cloudformation with custom providers - https://binx.io/2023/01/15/configure-custom-domain-for-aws-apprunner-service-using-cloudformation/

Given such basic functionality is still missing after almost a year and the CDK lib is still in alpha and still not have parity with Cloudformation, it would seem that AWS isn't investing in AppRunner anymore? Probably best to migrate away 😞

@nefilim Hi Peter. Do you know why this is not being worked on? We are considering a move from Render.com to App Runner (specifically because feature clients might require a dedicated VPC and Render can't offer this for now). Are you using App Runner, and do you think AWS has lowered the investment in it?

Also, do you know App runner, does not have an SLA?

@nefilim, what do you believe they are investing in instead? Copilot CLI is getting a lot of love and one of its deployment targets is App Runner with ECS on Fargate as alternative. It does look like ECS on Fargate is the default, however.

Does anyone know a CDK workaround until we have this feature? Links are also appriciated.

If this isn't going to be released soon can it get moved to not "Coming Soon"?
