It is easy to set up a keep-alive dyno ping using the Heroku scheduler. If you are a Ruby developer, you can create a rake task as follows, for an automated ping to your web dyno:
Write the following script:
desc "Pings YOUR_HEROKU_APP_URL to keep a dyno alive" task :wakeup_dyno do require "net/http" if ENV['YOUR_HEROKU_APP_URL'] uri = URI(ENV['YOUR_HEROKU_APP_URL']) Net::HTTP.get_response(uri) end endAdd
YOUR_HEROKU_APP_URLto your Heroku environment:$ heroku config:add YOUR_HEROKU_APP_URL=https://yourherokuapp.herokuapp.comNow, set up the Heroku scheduler:
$ heroku addons:add scheduler:standard $ heroku addons:open scheduler
That last command should open the scheduler interface in your browser.
Set up your
wakeup_dynotask to run once an hour and run it:$ rake wakeup_dyno
