[PATCH] settings: Wildcard 'ALLOWED_HOSTS' settings

Are you connecting using the IP address of the container/VM itself, or
are you using the port bound to localhost?
Without this patch, I can access localhost:8000 fine when I run
"docker-compose up". It's only when I try to connect directly to the
container using the container's IP address (In my case 172.17.0.3:8000)
that I get a DisallowedHost error.
I'm guessing the same thing occurs with Vagrant - if memory serves you'd
usually connect to the port bound to localhost - which should work. But,
if you connect to the VM directly it won't work.
I'm not opposed to the patch, I'm just curious as to why you'd ever
connect using the IP address.
