### Multiple Hosts ### Multiple Hosts
If you need to support multipe virtual hosts for a container, you can separate each enty with commas. For example, `foo.bar.com,baz.bar.com,bar.com` and each host will be setup the same.

### Separate Containers
nginx-proxy can also be run as two separate containers using the [jwilder/docker-gen](https://index.docker.io/u/jwilder/docker-gen/)
image and the official [nginx](https://registry.hub.docker.com/_/nginx/) image.
You may want to do this to prevent having the docker socket bound to a publicly exposed container service.
To run nginx proxy as a separate container you'll need to have [nginx.tmpl](https://github.com/jwilder/nginx-proxy/blob/master/nginx.tmpl) on your host system.
First start nginx with a volume:
$ docker run -d -p 80:80 --name nginx -v /tmp/nginx:/etc/nginx/conf.d -t nginx
Then start the docker-gen container with the shared volume and template:
```
$ docker run --volumes-from nginx \
-v /var/run/docker.sock:/tmp/docker.sock \
-v $(pwd)/templates:/etc/docker-gen/templates
-t docker-gen -notify-sighup nginx -watch --only-published /etc/docker-gen/templates/nginx.tmpl /etc/nginx/conf.d/default.conf
```
Finally, start your containers with `VIRTUAL_HOST` environment variables.
$ docker run -e VIRTUAL_HOST=foo.bar.com ...
