I've seen guides on how to deploy a DNS within a VNET for use with VM's, but I can't figure out how to do this for App Services. Especially since App Services don't have a static internal IP (at least not one that I can find in the portal).
Local environment
This is how my applications run on my local machine using docker-compose:
Production environment
In production, these applications are running as App Services (webapps for containers) inside a vnet.
In order to get the network traffic working, I thought I'd deploy an application gateway with a multi-site listener, and then add DNS records to point the "cat" and "dog" hostnames to the app gateway. But I can't find any guides on how to create DNS zone records for the app gateway, nor how to make the frontend AppService use that DNS for traffic within the vnet.
Maybe I should stop to ask, is this even the easiest approach? All I want is to let the frontend App Service be able to communicate with the backend services within thr VNET using simple hostnames.
Any ideas?
