I'm not opposed to adding these updates to the docker-compose yaml file, but they do need to be in ghost/stack.yml since the ghost/README.md file is generated.

Technically, the compose file will work as-is on docker-compose while still preserving the image-defined volumes when creating new containers (thus preserving state), they just won't have "pretty" names to keep track of them.

### Production mode with Apache2 as reverse proxy

This is just a general reverse proxy setup, so not something we want to focus our very limited documentation on.

You must update your configuration file, copy-and-paste the below block of configuration, amending it to suit your needs:
```
<VirtualHost *:*>
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPreserveHost on
ProxyPass "/" "http://127.0.0.1:8080/"
ProxyPassReverse "/" "http://127.0.0.1:8080/"
RequestHeader set "X-Forwarded-Proto" expr=%{REQUEST_SCHEME}
RequestHeader set "X-Forwarded-SSL" expr=%{HTTPS}
</VirtualHost>
```
For the proxy feature you should install:
```sh
sudo apt-get install libapache2-mod-proxy-html
sudo a2enmod proxy
sudo a2enmod proxy_html
sudo a2enmod proxy_http
sudo a2enmod headers
sudo service apache2 restart
```
