Google Cloud (API GATEWAY) Custom Domain

Question

I am currently building a rest api, for this I am using Google Cloud API Gateway and Google Cloud Run. I've been looking at all the google cloud documentation and researching elsewhere and I can't find how to add a custom domain to an API gateway instance. The funny thing is that there is more documentation for Google Cloud endpoints, I could find how to do it with endpoints but it does not apply to my use case.

I have 10 instances of google cloud run each one running a microservice respectively and I want to join everything in a single domain and add support with openapi, but I have failed in the attempt.

In any case, if someone has managed to customize the domain of an api gateway instance, I would appreciate if you could guide me, greetings.

Answer 1

For the beta release, custom domain names are not supported on GCP for API Gateway. Since it is still beta as of today, if you want to use a custom domain, you could use Cloud Endpoints in Cloud Run or you could even look into using Microservices in App Engine.
