[apigatewayv2] EDGE endpoint type is not supported for APIGatewayV2

[arichtman-srt]

Describe the bug

Creating DomainName resource for API Gateway v2 of Edge type is not possible.
API Gateway v1 controller has no DomainName resource, so it is not possible to use the v1 controller.

Steps to reproduce

1. Have valid ACM certificate in same region
2. Create DomainName with spec.domainNameConfigurations[*].endpointType "EDGE".

Expected outcome

Custom domain name of type EDGE is created.

Environment

• Kubernetes version: v1.32.5-eks-5d4a308
• Using EKS (yes/no), if so version? Yes, v1.32.5-eks-5d4a308
• AWS service targeted (S3, RDS, etc.): API Gateway v2

It's a valid enum for the custom resource https://github.com/aws-controllers-k8s/apigatewayv2-controller/blob/df8020bbe2ae362723c9fce7e6b5c4d5d587cfaa/apis/v1alpha1/enums.go#L68

Is the API Gateway v1 controller supposed to have a DomainName resource or specification? It's typed out https://github.com/aws-controllers-k8s/apigateway-controller/blob/c2b48001ed47c89cbeeaf862ebac0e03ef39c065/apis/v1alpha1/types.go#L145

Thank you for reporting this issue!

I can confirm this is expected behavior per AWS documentation. HTTP APIs (API Gateway v2) only support REGIONAL endpoint types, not EDGE endpoint types, as documented here: https://docs.aws.amazon.com/apigateway/latest/developerguide/http-api-vs-rest.html

We can add domain name support to the API Gateway v1 controller to support edge-optimized endpoints. Would you like us to create a feature request for this enhancement? In the meantime, please use the REGIONAL endpoint type for your API Gateway v2 domain name.

Yes please! Feature request for API Gateway v1 - let me know if I can help! I'm a little time-poor at work atm though 😔
