BitBucket Server 5.2 - hostname?

[PaulA]

I had BitBucket 4.9 hanging off an AWS server at  http://stash.mydomain.com.au, with the hostname alias configured in the server.xml file ..

 <Engine name="Catalina" defaultHost="localhost">
 <Alias>stash.mydomain.com.au</Alias>
 <Alias>(IP Address here)</Alias>

Upgrading to 5.2.2, I'm trying to figure out how to duplicate this in the bitbucket.properties file. I've configured the server.port there, but not sure how to configure the hostname to watch for.

Thanks!
