OpenResty: The overpowered web server used by 40M websites (that people rarely talk about)

• LuaWeb

  1 171 10.0 Lua

  A very simple blog engine using openresty, nginx, lua, markdown, git and redis

Someone even made their blogging site only with OpenResty and Redis; they did not use any other backend application: https://github.com/torhve/LuaWeb. Unfortunately, they implied OpenResty to be a bunch of plugins; however, it’s a fully functional web platform on its own with its vast library of official and third-party modules.

  Reverse proxying app instances registered on Consul via DNS (SRV) using OpenResty

I used OpenResty for load balancing my Flask applications registered on a Consul service mesh. I sent DNS requests to the Consul server using Lua to fetch the application instances, and then proxied the requests to the application. Without OpenResty, I would have to use another Python application as an API gateway, which would be slower, and more agonizing. With a single Lua file, I turned OpenResty into a dynamic load balancer that uses Consul as its service discovery. Here’s the repository for my project: https://github.com/ahnaf-zamil/openresty-consul-proxy/

  Ingress-NGINX Controller for Kubernetes

  

Even a lot of people who claim to be using Nginx are actually using the Lua module which was made by and for OpenResty. The Kubernetes Nginx ingress controller uses OpenResty under the hood through its Lua module: https://github.com/kubernetes/ingress-Nginx/blob/88e96decd95e7bd10e7de62b102284ff2bc82593/docs/how-it-works.md

Anyways, I recommend you check out OpenResty’s website (https://openresty.org) first. OpenResty offers binary packages, but you can also compile from source code. I used the latter option (because I have an obsession with compiling stuff from scratch), and it didn’t take me long to do it, about 4-5 minutes.
