In line 6, what kind of domain can be used? it will be the one players will enter in order to join and play in the server?
I'm really intrigued about this: players joining a live mc server running in a docker deployed in azure. Does your file do the trick? what steps would I need to do to make it work?

You do get a fully qualified domain name (FQDN) but it is under an azure owned domain. Here is the naming convention:
{domainname}.{region}.azurecontainer.io

The domain name label is provided with the service (line 6). The region is controlled by the resource group under which your docker ACI context is setup.

To get your container mapped to your custom domain you can setup a CNAME record pointing at The Azure FQDN.
