Heroku Buildpack: Run
Run custom commands during the build process.
This buildpack allows to execute arbitrary commands on the build dyno during the build process by sourcing one or more files with Bash commands.
Add the buildpack to your app:
heroku buildpacks:add https://github.com/weibeld/heroku-buildpack-run.git
Create the file
buildpack-run.sh in the root directory of your app, for example:
echo "Hello World"
Now push your app to Heroku as usual. The commands in
buildpack-run.sh will be executed during the build.
Optional: use a different filename
If you want to use another filename than
buildpack-run.sh, then you can specify this filename in the app config variable
BUILDPACK_RUN. For example, if your file is called
heroku config:set BUILDPACK_RUN=my_file.sh
Optional: use multiple files
You can specify multiple files to
BUILDPACK_RUN by separating them with colons. For example, if you want to source the files
my_file_2.sh in this order, then set your
BUILDPACK_RUN as follows:
heroku config:set BUILDPACK_RUN="my_file_1.sh:my_file_2.sh"
- The working directory of the shell in which your commands will be executed is the root directory of your app
- The paths of the files specified to
BUILDPACK_RUNmust be relative to the root directory of your app
- You can use the command
exit 1in your files to abort the build
- The following build-specific shell variables are available to your command files:
BUILD_DIR: path to the root directory of your app on the build dyno
ENV_DIR: the directory holding all your app's config variables as files
CACHE_DIR: directory whose content persists across builds of your app
