Question

I have Docker configured to run Postgres and Django using docker-compose.yml and it is working fine.

The trouble I am having is with Selenium not being able to conne

Answer 1

Whenever you see localhost, try first to port-forward that port (at the VM level)

See "Connect to a Service running inside a docker container from outside"

VBoxManage controlvm "default" natpf1 "tcp-port8081,tcp,,8081,,8081"
VBoxManage controlvm "default" natpf1 "udp-port8081,udp,,8081,,8081"

(Replace default with the name of your docker-machine: see docker-machine ls)

This differs for port mapping at the docker host level (which is your boot2docker-based Linux host)

The OP luke-aus confirms in the comments:

entering the IP address for the network solved the problem!
