Running demos on Heroku
Running the demos of Dallinger in “sandbox” mode, will require a Heroku account and verification by providing a credit card in your Heroku account. If you only make use of Heroku’s free tier offerings, you will not be charged.
Heroku states that the use of any add-on requires account verification (even free tier add-ons). Redis is a requirement for Dallinger to run and is considered by Heroku as an add-on feature. More information on account verification can be found here.
If you wish to only make use of Heroku’s free tier offerings, set the following in the demo’s config.txt file:
database_size = standard-0 redis_size = premium-0
Also note that you may also need to set:
dyno_type = basic
