A Heroku Buildpack to add Datadog relay to any Dyno.


This buildpack is typically used in conjunction with other languages, so is most useful with the heroku-buildpack-multi buildpack, and language-specific buildpacks - see Heroku Language Buildpacks for more.

Here are some setup commands to add this buildpack to your project, as well as setting the required environment variables:

cd <root of my project>
# Prepend the .buildpacks file with the URL
touch .buildpacks ; echo "https://github.com/miketheman/heroku-buildpack-datadog.git" | cat - .buildpacks > /tmp/out && mv /tmp/out .buildpacks
git commit -i .buildpacks -m "Add Heroku Buildpack Datadog"

heroku create # only if this is a new heroku project
heroku config:add BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git
heroku config:set HEROKU_APP_NAME=$(heroku apps:info|grep ===|cut -d' ' -f2)
heroku config:add DATADOG_API_KEY=<your API key>

git push heroku master

You can create/retrieve the DATADOG_API_KEY from your account on this page. API Key, not application key.

Once complete, the Agent's dogstatsd binary will be started automatically with the Dyno startup.

Once started, provides a listening port on 8125 for statsd/dotstatsd metrics and events.


Things that have not been tested, tried, figured out.

  • see if we can bypass apt updates on every run
  • determine how the compiled cache behaves with new releases of the datadog-agent package, as it stored the deb file
  • tag release when stable, update docs on how to use a given release in q.buildpacks


  • Fork this repo
  • Check out the code, create your own branch
  • Make modifications, test heavily. Add tests if you can.
  • Keep commits simple and clear. Show what, but also explain why.
  • Submit a Pull Request from your feature branch to master


This buildpack was heavily inspired by the heroku-buildpack-apt code, as well as many others from Heroku and @ddollar. We leverage the same type of process runner that the Datadog Docker container uses, with a couple of modifications.
