Heroku Ping Save Abandoned

A utility to ping heroku web applications and keep them alive.

Project README

heroku-ping: keep your heroku websites alive

Like some people, I use heroku to keep my homepage alive. Unfortunately, the heroku dynos are powered down if they don't get requests in a certain amount of time, meaning visitors to your site often experience a nasty delay.

This is a heroku application that pings a URL every 20 minutes to fix that. No more, no less.



Clone the repo, create an app.

$ git clone https://github.com/thoughtpolice/heroku-ping.git
$ cd heroku-ping
$ heroku create ping-MYAPP
Creating ping-MYAPP... done, stack is cedar
http://ping-MYAPP.herokuapp.com/ | [email protected]:ping-MYAPP.git
Git remote heroku added

Now add the URL of the heroku application you want to ping using the PING_URL environment variable.

See list of accepted variables below

$ heroku config:add PING_URL=http://MYAPP.herokuapp.com
Setting config vars and restarting ping-MYAPP... done, v3
PING_URL: http://MYAPP.herokuapp.com

Now push, and scale the worker to 1 instance.

$ git push heroku master
-----> Ruby app detected
-----> Installing dependencies using Bundler version 1.3.0.pre.5
-----> Discovering process types
       Procfile declares types -> worker
       Default types for Ruby  -> console, rake
-----> Compiled slug size: 688K
-----> Launching... done, v5
       http://ping-aseipp.herokuapp.com deployed to Heroku
$ heroku ps:scale worker=1
Scaling worker processes... done, now running 1

You're done. Now your web application will be kept alive! You can make sure it's working by checking heroku logs.
