Compose: Allow for adding extra_hosts to another container

[aequasi]

Let me know if this isnt the way i should be doing this, but i have the following config:

version: '2'
services:
    webserver:
        image: abiosoft/caddy
        ports:
            - 80:80
        // ... Some other stuff
     api:
         // ... Normal stuff
     www:
         // ... Normal stuff
         extra_hosts:
             - "dev.api.example.com:webserver"

The webserver has multiple vhosts in it, and nothing defaulted, so i can't use webserver. I cant expose the port on the api container, as its not a webserver.

I don't think that'll work. Use network aliases instead.

Ah ha, that works! Thank you!
