Reverse Proxy a INSPIRE Atom service with NGINX

Minimal NGINX config to reverse proxy a INSPIRE Atom service and manipulate the response body as well as response headers. Intented for debugging purposes.

Start the NGINX reverse proxy:

docker run --name mynginx1 -p 8282:80 -d -v $(pwd)/nginx.conf:/etc/nginx/conf.d/default.conf anroe/nginx-headers-more

To serve out the proxied INSPIRE Atom service on a public url use ngrok (also substitute a working ngrok url in the nginx conf):

ngrok http 8282

nginx.conf
