Dockerfile not port forwarding about toxiproxy HOT 4 CLOSED

We just --net=host I believe. It sounds useful to forward by default though.

from toxiproxy.

The current Dockerfile already has the port defined: https://github.com/Shopify/toxiproxy/blob/master/Dockerfile#L8
There's no way to actually make it forward with default arguments though.
What you want is the -P argument, which will forward all the ports defined in the Dockerfile.

This doesn't seem to forward any ports for me but I could be very well missing something here.

The problem with using this is that it ends up giving a random port which might a PITA to manage in your tests if you need to reference it.

$ docker run -it -d -P shopify/toxiproxy

I think to make this slightly easier for out of the box usage, we could update the documentation to include -p 8474:8474 (which I feel would solve my concerns from above).

--net=host assumes that all other containers are in the same networking namespace (i.e. they're run with --net=host) or that you don't run other tests in a networking namespace (e.g. not in a container).
