Add docker-compose file for separate containers.
Demonstrate that this pattern works. This is based on the example at <https://github.com/fatk/docker-letsencrypt-nginx-proxy-companion-examples/blob/master/docker-compose/v2/simple-site/docker-compose.yml>.

You may want to do this to prevent having the docker socket bound to a publicly exposed container service.
|
||||
|
||||
You can demo this pattern with docker-compose:
|
||||
|
||||
```console
|
||||
$ docker-compose --file docker-compose-separate-containers.yml up
|
||||
$ curl -H "Host: whoami.local" localhost
|

I'm 5b129ab83266

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:
