multi-buildpack

Cloud Foundry Experimental Multi-buildpack

Join us on Slack

This buildpack allows you to run multiple buildpacks in a single staging container.

Usage

• This buildpack looks for a multi-buildpack.yml file in the root of the application directory with structure:

buildpacks:
  - https://github.com/cloudfoundry/go-buildpack
  - https://github.com/cloudfoundry/ruby-buildpack/releases/download/v1.6.23/ruby_buildpack-cached-v1.6.23.zip
  - https://github.com/cloudfoundry/nodejs-buildpack#v1.5.18
  - https://github.com/cloudfoundry/python-buildpack#develop

• The multi-buildpack will download + run all the buildpacks in this list in the specified order.

• It will use the app start command given by the last buildpack run.

Details

• This will not work with system buildpacks. Ex. the following multi-buildpack.yml file will not work:

buildpacks:
  - ruby_buildpack
  - go_buildpack

• The multi-buildpack will run the bin/compile and bin/release scripts for each specified buildpack.

Testing

Buildpacks use the Machete framework for running integration tests.

To test a buildpack, run the following command from the buildpack's directory:

BUNDLE_GEMFILE=cf.Gemfile bundle exec buildpack-build

More options can be found on Machete's Github page.
