On: Gixy: Nginx Configuration Static Analyzer

'nginx -t' exists as a general syntax checker, would be neat to expand it further to include these in depth checks.

What's annoying about the built-in checker is that it attempts to connect proxypass backends. So if you want to run this in CI you will get connection refused errors.

Put the proxy settings into variables and you can sidestep that. It also allows NgINX to start up when the backends may not be running.

e.g.

    set $upstream_app         backend;
    set $upstream_port        8888;
    set $upstream_proto       http;
    proxy_pass                $upstream_proto://$upstream_app:$upstream_port;

On the other hand, if it never checked those, you would run into problems, when you rely on those being available and somehow they are not.
