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

	#!/bin/sh

	# This program has two feature.
	#
	# 1. Create a disk image on RAM.
	# 2. Mount that disk image.
	#
	# Usage:
	# $0 <dir> <size>
	#

	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").

	Latency Comparison Numbers (~2012)
	----------------------------------
	L1 cache reference 0.5 ns
	Branch mispredict 5 ns
	L2 cache reference 7 ns 14x L1 cache
	Mutex lock/unlock 25 ns
	Main memory reference 100 ns 20x L2 cache, 200x L1 cache
	Compress 1K bytes with Zippy 3,000 ns 3 us
	Send 1K bytes over 1 Gbps network 10,000 ns 10 us
	Read 4K randomly from SSD* 150,000 ns 150 us ~1GB/sec SSD

	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
