Using a dynamic value for allow-hosts

[bendavis78]

We need to be able to set allow-hosts to a list of docker containers in a project (this list is generated by our internal python library). Is there a way to do this in conftest.py?

@bendavis78 That's an interesting challenge - I guess a lot depends on how you're constructing your list of containers. There's no current method I'm aware of for supplying that "globally" in conftest.py, but that doesn't mean it doesn't exist.

Thinking about it, you might try to work with the pytest_configure hook in your conftest.py, and have that happen after pytest-socket has been configured, and inject your own allow_hosts there? Hopefully this helps!
