### Hub and Nodes Using Docker Networking
``` bash
docker network create selenium-network
docker run -d -p 4444:4444 --net=selenium-network --name selenium-hub selenium/hub:2.48.2
docker run -d --net=selenium-network -e HUB_HOST=selenium-hub selenium/node-chrome:2.48.2
docker run -d --net=selenium-network -e HUB_HOST=selenium-hub selenium/node-firefox:2.48.2
```
You can also pass in an IP address, if your selenium hub is location on a different physical machine:
``` bash
docker run -d -e HUB_HOST=10.0.0.1:4444 selenium/node-chrome:2.48.2
docker run -d -e HUB_HOST=10.0.0.1:4444 selenium/node-firefox:2.48.2
```
