This is a Heroku buildpack that allows one to multiple other buildpacks in a single deploy process. This helps support:
- Running multiple language buildpacks such as JS for assets and Ruby for your application
- Running a daemon process such as pgbouncer with your application
- Pulling in system dependencies.
To use this buildpack you'll first need to set it as your custom buildpack:
$ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-multi.git
From here you will need to create a .buildpacks file which contains (in order) the buildpacks you wish to run when you deploy:
$ cat .buildpacks
https://github.com/heroku/heroku-buildpack-nodejs.git#0198c71daa8
https://github.com/heroku/heroku-buildpack-ruby.git#v86
