Nginx binaries builds for Heroku

About

• Dynamically linked, with lua, http2, geoip etc., built in Heroku build docker images.
• Bins committed to the repository, being downloaded from releases by Heroku runtime (saving bucks on S3 traffic).
• Comes with mime.types, also included in releaes.
• Nginx compile options changable in scripts/build-nginx.sh.
• Inspired by https://github.com/Americastestkitchen/heroku-buildpack-nginx

Usage

• Requires docker.

make <shell|build[-cedar-14|-heroku-[16,18,20]]

• Result in bin/.

Heroku 20 commentary

Due to compatibility reasons, nginx bin for heroku-20 stack is built on heroku-18 build docker image. It uses latest nginx available (1.19.6 at the time of update), a bit older gcc to actually build it and a bit older nginx dev kit and lua in order to run nginx with lua without any other dependencies needed (LuaJIT2 e.g.). Compatible with heroku-18 stack.

Current nginx Heroku 20 runtime requirements

• Folder /tmp/nginx/log.

Running Heroku 20 nginx

./nginx -p . -c </path/to/conf>

Working example

#!/bin/bash

set -e

erb heroku/nginx.conf.erb > heroku/nginx.conf

mkdir -p /tmp/nginx/log
( cd /tmp/nginx/log && touch access.log error.log )

( tail -qF -n 0 /tmp/nginx/log/*.log ) & # get nginx logs directly into Heroku logs

curl -sSL https://github.com/salsita/nginx-heroku-build/releases/download/v1.0/nginx-heroku-20 \
   > nginx
 chmod +x nginx

curl -sSL https://github.com/salsita/nginx-heroku-build/releases/download/v1.0/mime.types \
   > heroku/mime.types

echo Starting nginx
./nginx -p . -c heroku/nginx.conf

• heroku/nginx.conf contains full nginx configuration (as /etc/nginx/nginx.con does, sites included).
