server location

[iotexpert]

By default the /etc/nginx/conf.d/nginx.conf is created for you.... and it looks something like this:
server {
listen 80;
location / {
try_files $uri @app;
}
location @app {
include uwsgi_params;
uwsgi_pass unix:///tmp/uwsgi.sock;
}
}

This is done by the script "entrypoint.sh" ... which has a bunch of "content_server= ... " ending with a print "$content_server" > /etc/nginx/conf.d/nginx

I need to be able to add some more locations to the server definition block... specifically a location that returns a 404 for files that end in json... which needs to look like this:

location ~ (.json$) {return 404;}

I can only think of ugly ways to do this...

1. I suppose I can modify the entrypoint script... and add do a pull request
2. I can make a nginx.conf that combines /etc/nginx/nginx.conf and the generated code + my addition

Dont really like either one of my ideas. What is the proper way?

Thanks,
Alan
