Access to heroku toolbelt commands in a scheduled heroku dyno?

Question

I want to call heroku postgres backup/restore commands within a scheduled heroku task, but the heroku toolbelt isn't available from bash prompt, so I can't call heroku commands:

$ heroku run bash --app myapp
Running `bash` attached to terminal... up, run.4805
~ $ heroku --version
bash: heroku: command not found

How can I get heroku commands available in my scheduled bash script? I don't know anything about Ruby or Ruby Gems.

None of the other solutions worked for me since Heroku locks the filesystem after the buildpacks finish running.

There's a third-party buildpack that installs the CLI for you. First you set your auth key as an ENV variable on your app:

heroku config:set HEROKU_API_KEY=`heroku auth:token` -a myapp

Then add the buildpack:

heroku buildpacks:add https://github.com/heroku/heroku-buildpack-cli -a myapp

Redeploy your app and it should be able to access your apps via the CLI. If you have https://devcenter.heroku.com/articles/dyno-metadata enabled, you can even access your current app's name with $HEROKU_APP_NAME.
