Restart my heroku application automatically

Question

This terminal command restarts my heroku application:

heroku restart

Is there a way to run a script that will run this command and restart

Answer 1

We solved this by using a buildpack to get the heroku command available to the dyno itself, then using Heroku Scheduler.

We added the https://github.com/gregburek/heroku-buildpack-toolbelt buildpack per its instructions:

heroku buildpacks:add https://github.com/gregburek/heroku-buildpack-toolbelt.git
heroku config:add HEROKU_TOOLBELT_API_EMAIL=`heroku whoami`
heroku config:add HEROKU_TOOLBELT_API_PASSWORD=`heroku auth:token`

Then made sure the app slug was rebuilt per the instructions:

git push heroku master

In Heroku Scheduler, we added this as a hourly job:

vendor/heroku-toolbelt/bin/heroku ps:restart -a $HEROKU_APP_NAME

You can determine if it's working by looking for Scheduler output in the Heroku logs, and of course by the memory graph of the app in the Heroku dashboard (if you're restarting to work around a memory leak).
