Heroku Buildpack: NGINX-1.17.1

Nginx-buildpack vendors NGINX inside a dyno and connects NGINX to an app server via UNIX domain sockets.

Requirements

• Your webserver listens to the socket at /tmp/nginx.socket.
• You touch /tmp/app-initialized when you are ready for traffic.
• You can start your web server with a shell command.

Language/App Server Agnostic

Nginx-buildpack provides a command named bin/start-nginx this command takes another command as an argument. You must pass your app server's startup command to start-nginx.

For example, to get NGINX and Unicorn up and running:

$ cat Procfile
web: bin/start-nginx bundle exec unicorn -c config/unicorn.rb

Setting the Worker Processes

You can configure NGINX's worker_processes directive via the NGINX_WORKERS environment variable.

For example, to set your NGINX_WORKERS to 8 on a PX dyno:

$ heroku config:set NGINX_WORKERS=8

Customizable NGINX Config

You can provide your own NGINX config by creating a file named nginx.conf.erb in the config directory of your app. Start by copying the buildpack's default config file.
