A lightweight haproxy container that bounces TCP connections to a single backend.
To use this image, set the BACKEND_HOST and BACKEND_PORT environment
variables, forward port 5000, and run with no arguments.
docker run -p 5000:5000 -e BACKEND_HOST=www.google.com -e BACKEND_PORT=443 jerithorg/tcpbouncer
In addition, there is an optional FRONTEND_PORT envvar for people who want
the container to listen on a different port. This may be useful with host
networking.
