Include the server config in the compose file?

[plattrap]

One magic I had to work out is to double the "$" in the config content so that Docker does not try and expand the TS_CERT_DOMAIN string.

Also commented out the funnel line, because if it is in (even set to false), then the container shows as funnel enabled in the
control panel.
