Heroku Buildpack for Nginx + SSL

This buildpack gives your app access to the nginx command compiled with SSL support.

Features

• Downloads and compiles Nginx 1.5.7 with PCRE
• SSL support via --with-http_ssl_module
• Adds nginx to your app's PATH
• Additional files (mime.types, example configs, etc) are available at $HOME/nginx if you need them.
• Your app must generate nginx.conf and run nginx itself (explained below)

Usage

You can check out a complete "hello world" example app at nginx-ssl-buildpack-example.

Creating a new app with this buildpack

# Create your app if you haven't already
heroku create

# Set the buildpack URL
heroku config:set BUILDPACK_URL=https://github.com/ddgromit/nginx-ssl-buildpack

After adding the buildpack, nginx will be available on your path. It is the responsibility of your app and it's Procfile to call nginx with a nginx.conf that you've generated.

You must generate nginx.conf yourself because what port you're using depends on the PORT environment variable, which is different on every app.

Procfile example

Here we use ERB to generate a nginx.conf at dyno start time.

web: erb nginx.conf.erb > nginx.conf && nginx -c $HOME/nginx.conf

nginx.conf.erb example

The nginx.conf.erb can access environment variables like the port it needs to use.

worker_processes <%= ENV['NGINX_WORKERS'] || 4 %>;
daemon off;

events {
  worker_connections 768;
}

http {
  server {
    listen <%= ENV["PORT"] %>;
    server_name _;

    location / {
      return 200;
    }
  }
}

Customization

There's a few reasons you might fork this buildpack.

• add custom modules during compilation
• keep your own version of this repo for security and permanence
• make improvements

I'd encourage you to update the README to explain how your buildpack is special, and consider creating a PR back to this repository.

There are a few ways to use your own version of this buildpack in your app.

# Create a new Heroku app that uses your buildpack
heroku create --buildpack <your-github-url>

# Configure an existing Heroku app to use your buildpack
heroku config:set BUILDPACK_URL=<your-github-url>

# You can also use a git branch!
heroku config:set BUILDPACK_URL=<your-github-url>#your-branch
