Run custom commands during the build process.
This buildpack allows to execute arbitrary commands on the build dyno during the build process.
Just create the file
buildpack-run.sh in the root directory of your application and write in this file the commands that you want to execute. This file is then sourced by the
compile script of this buildpack. That is, the commands in
buildpack-run.sh are executed on the build dyno as they would be part of the
Available build-specific variables are
All config variables are available.
The initial working directory is the root directory of your application.
For aborting the build at any point, you can use the
exit command with a non-zero exit code, e.g.
This buildpack is useful for finding out information about the build process.
# Create file 'buildpack-run.sh' containing bash commands echo 'echo "hello world"' > buildpack-run.sh heroku buildpacks:set https://github.com/damiencriado/heroku-buildpack-run.git
The buildpack is now set and will be used on the next deploy.
For more information on how to use custom buildpacks, see https://devcenter.heroku.com/articles/third-party-buildpacks#using-a-custom-buildpack.
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/php heroku buildpacks:add --index 2 https://github.com/damiencriado/heroku-buildpack-run.git
You can always check which buildpacks you have currently added to your app with:
The default name of the source script is
buildpack-run.sh, but you can set whatever you want:
heroku config:set BUILDPACK_RUN="buildpack-run-staging.sh"
Copy the snippet above into CLI.
