What are the best practices with Heroku add-ons? I manage multiple Heroku apps. I want them to share a common add-on. how to do that?
For example, first I signed up for Mandrill on their website. When I added Mandrill add-on on Heroku, they created a new Mandril account for me. I wanted to merge them but Mandril support said that they can't merge accounts!
Another example, I added Logentries add-on to one Heroku app. A Logentries account was created. Then I added another Logentries add-on to another Heroku app, then another Logentries account was created.
It's getting messy. Am I doing it right? How to make several Heroku apps share one add-on account?
Yes, you're doing it right. Each Heroku app is a separate instance and will get its own add-ons. There is no way to share add-ons across multiple Heroku apps, as far as I know.
