Run custom commands during the build of a Heroku app

Heroku Buildpack: Run

Run custom commands during the build process.

Description

This buildpack allows to execute arbitrary commands on the build dyno during the build process.

To use it, you have to create the file buildpack-run.sh in the root directory of your app. This file can contain arbitrary Bash commands. If you then activate the buildpack (see below), buildpack-run.sh will be sourced during the build. The working directory will be the root directory of your application.

This buildpack is useful for finding out information about the build process.

Usage

Simply do

# Create file 'buildpack-run.sh' containing bash commands
echo 'echo "hello world"' >buildpack-run.sh

heroku buildpacks:set https://github.com/weibeld/heroku-buildpack-run.git

On the next git push heroku master, the heroku-buildpack-run buildpack will be used.

For more information on how to use custom buildpacks, see https://devcenter.heroku.com/articles/third-party-buildpacks#using-a-custom-buildpack.

Usage together with other buildpacks

You can use multiple buildpacks at the same time as described on https://devcenter.heroku.com/articles/using-multiple-buildpacks-for-an-app:

heroku buildpacks:add --index 1 heroku/ruby
heroku buildpacks:add --index 2 https://github.com/weibeld/heroku-buildpack-run.git

You can always check which buildpacks you have currently added to your app with:

heroku buildpacks
