What port is mapped to the FQDN of an Azure Container Instance when multiple ports are opened?

Question

Title basically says it. The official MS documentation only says that you can connect to the container via the FQDN. So I assumed that when I open one port it would connect me to that port of the container. But what happens when I open more than one port?

FQDN (fully qualified domain name) doesn't include port, so your container would be exposed via the combination of FQDN and whatever ports you open. For example:

http://something.somewhere.azurecontainer.io:8080 (Postgres pgadmin web interface)
something.somewhere.azurecontainer.io:5432 (Postgres DB engine)
