This is an example of using Linux Kernel's Transparent Proxy to route all TCP traffic to docker containers without having to resort to PROXY protocol which is not supported by some applications (e.g. sshd). To get the demo to work you only need vagrant installed:

git clone [this-gist] tproxy-demo
cd tproxy-demo
vagrant up

Mac OS X has only 16K ports available that won't be released until socket
TIME_WAIT is passed. The default timeout for TIME_WAIT is 15 seconds.
Consider reducing in case of available port bottleneck.

You can check whether this is a problem with netstat:

    # sysctl net.inet.tcp.msl
    net.inet.tcp.msl: 15000

    # sudo sysctl -w net.inet.tcp.msl=100

This file tests a direct-threaded interpreter with the ability to
switch the mode (by modifying the dispatch table).

It uses one non-standard feature supported by GCC and Clang on Darwin,
namely "Labels as Values" (the syntax "&&label_name").
