Heroku buildpack: nginx

This is a Heroku buildpack for nginx.

Usage

Example usage:

$ ls -R *
conf:
mime.types     nginx.conf.erb

html:
index.html

$ heroku create --stack cedar --buildpack http://github.com/essh/heroku-buildpack-nginx.git
...

$ git push heroku master
...
-----> Heroku receiving push
-----> Fetching custom buildpack... done
-----> Nginx app detected
-----> Fetching nginx binaries
-----> Vendoring nginx 1.0.11
...

The buildpack will detect your app as nginx if it has the file nginx.conf.erb in the conf directory. You must define all listen directives as listen <%= ENV['PORT'] %>; and also include daemon off; in order for this buildpack to work correctly.

Hacking

To modify this buildpack, fork it on Github. Push up changes to your fork, then create a test app with --buildpack <your-github-url> and push to it.

To change the vendored binaries for nginx use the helper script in the support/ subdirectory. You may wish to edit the helper script to modify the nginx build options to suit your needs. You'll need an S3-enabled AWS account and a bucket to store your binaries in.

For example, you can change the vendored version of nginx to 1.0.12.

First you'll need to build a Heroku-compatible version of nginx:

$  export AWS_ID=xxx AWS_SECRET=yyy S3_BUCKET=zzz
$ s3 create $S3_BUCKET
$ support/package_nginx 1.0.12 8.30

The first argument to the package_nginx script is the nginx version. The second argument is the version of PCRE to compile nginx against.

Open bin/compile in your editor, and change the following lines:

NGINX_VERSION="1.0.12"
S3_BUCKET=zzz

Commit and push the changes to your buildpack to your Github fork, then push your sample app to Heroku to test. You should see:
