In my bid to host my ruby based telegram bot on heroku, I had to jump through hoops due to the fact that my bot was not using webhooks but the polling alternative.
This required that I run a script to initiate the bot. This also meant that my bot had no web interface.
Most important
REMEMBER TO SET ENV VARIABLES IN HEROKU'S CONFIG VAR
Add a Procfile to the root of your app.
Sample Procfile:
bot: bundle exec ruby app.rb
Make sure you have installed Heroku’s CLI. Run the following command:
heroku ps:scale bot=1 -a <appname>
Note here that ‘bot’ here is same and similar to ‘bot’ in the procfile
and
heroku run bundle exec ruby <app.rb> -a <appname>
Thats it. This should get you going?
