synctree/sinatra-echo repository overview

⁠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
