Docker compose extra hosts with wildcards

I'm trying to create a container based on PHP:5-apache with many virtual hosts like

I can add all the vhosts with a wildcard on the apache conf. Is it possible to do something similar for the hosts file?

Docker sets up the hosts file when you run a container, so you don't want to manually edit it. Instead you can use the add-host option:

> docker run --add-host 1.local:127.0.0.1 alpine ping 1.local
PING 1.local (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: seq=0 ttl=64 time=0.050 ms

You can have multiple add-host options in the run command.

In Docker Compose the equivalent is extra-hosts:

extra_hosts:
 - "1.local:127.0.0.1"
 - "2.local:127.0.0.1"
