h-app-roxy

Installing the dependencies

• Save Thierry Fournier’s fifo.lua into your Lua search path. You can find the source on his blog: http://blog.arpalert.org/2018/02/haproxy-lua-fifo-and-asynchronous.html
• Save Thierry Fournier’s redis-pool.lua into your Lua Search path. You can find the source on his blog: http://blog.arpalert.org/2018/02/haproxy-lua-redis-connection-pool.html
• Replace r.release(conn) with r:release(conn) in redis-pool.lua.
• Install lua-redis. On Ubuntu Xenial I had to symlink the script manually in the Lua 5.3 library path, it was installed for Lua 5.1 / 5.2 only. Bug report is here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=898013

Installing h-app-roxy

• Put the h_app_roxy.lua script into your Lua search path.

Using h-app-roxy

core.register_service("shorturl", "http", require("h_app_roxy"){
	# Routes go here
})

Check out shorturl.lua for an example application.

Disclaimer

This project is intended as a joke to explore the abilities of haproxy’s Lua API. It is slippery when wet, do not use this at home. Definitely do not use this at work. If it breaks you get to keep both pieces.
