`GHOST_PORT` is useless as the ghost docker image listens to hardcoded port 2368

[tmlmt]

In the example .env file, there's a section that says:

ghost-docker/.env.example

Lines 49 to 52 in 1fb6d85

	# Port Ghost should listen on
	# You should only need to edit this if you want to host
	# multiple sites on the same server
	# GHOST_PORT=2368

However the only place this variable is used in the entire TryGhost org is in the compose file, which uses a wrong syntax for the expose attribute as explained in #54

In fact, the only way the port can be changed is by setting the env variable server__port=xxxx and exposing that same port in the compose file.

I just spend over an hour resolving this issue. Documentation is not very good in this matter.

1. There is caddy already in the compose file. That will confuse many people as most of the user will already be using some sort of reverse proxy. Compose should not assume that and caddy should be removed in my opinion.

2. Compose file shows DNAT for ghost (80:80 and 443:433). First of all, again, ports 80 and 443 are probably already used for something else by most of the users. Second, in https://docs.ghost.org/install/docker there is not a single mention about port 2368. That is the port on which ghost listens to and that is the port you need to expose to a reverse proxy. On the first look it looks like you should set your reverse proxy to 443 which will not work
