Heroku Buildpack Nginx

This buildpack will work out-of-the-box with nginx. It installs nginx, add authentication and some other cool stuff. Inspired by and copied from tonycoco/heroku-buildpack-ember-cli.

By default it will serve the website from the html directory. You can easily overwrite that in the custom nginx config file or with the heroku config variables.

Usage

Creating a new Heroku instance from the application's parent directory:

$ heroku create --buildpack https://github.com/mgmco/heroku-buildpack-nginx.git

$ git push heroku master
...
-----> Heroku receiving push
-----> Fetching custom buildpack
...

Or add buildback to existing Heroku app

$ heroku config:add BUILDPACK_URL=https://github.com/mgmco/heroku-buildpack-nginx.git

Configuration

Variables

You can set a few different environment variables to turn on features in this buildpack.

Root directory

Set the root directory with you website (Default: html):

heroku config:set ROOT_DIRECTORY=html

Nginx Workers

Set the number of workers for Nginx (Default: 4):

heroku config:set NGINX_WORKERS=4

Authentication

Have a staging server? Want to protect it with authentication? When BASIC_AUTH_USER and BASIC_AUTH_PASSWORD are set basic authentication will be activated:

heroku config:set BASIC_AUTH_USER=EXAMPLE_USER
heroku config:set BASIC_AUTH_PASSWORD=EXAMPLE_PASSWORD

Be sure to use https when you set this up for added security.

Force HTTPS/SSL

For most Ember applications that make any kind of authenticated requests (sending an auth token with a request for example), HTTPS should be used. Enable this feature in nginx by setting FORCE_HTTPS.

heroku config:set FORCE_HTTPS=true

Redirect not found to

Have one index.html file and you want to redirect everything not found to that single file?

heroku config:set REDIRECT_NOT_FOUND_TO=/index.html

Before and After Hooks

You can run your own scripts by creating after_hook.sh or before_hook.sh files (or both) in your app's hooks directory:

mkdir hooks
cd hooks
touch after_hook.sh
touch before_hook.sh

Custom Nginx

Need to make a custom nginx configuration change? No problem. In your application, add a config/nginx.conf.erb file. You can copy the existing configuration file in this repo and make your changes to it.
