synctree/sinatra-echo

The synctree/sinatra-echo image provides a simple HTTP app that echoes back the headers and parameters sent with a request along with standard CGI variables. It is useful for debugging the HTTP payload seen by an application running behind one or more layers of proxying.

Usage

To run the HTTP echo service exposed directly on port 80:

$ docker run -d -p 80:9292 synctree/sinatra-echo

To run the HTTP echo service behind jwilder/nginx-proxy:

$ docker run -d -e VIRTUAL_HOST=echo.example.com synctree/sinatra-echo
