[FEATURE] app.json

[dwreeves]

Overview

The app.json is a Heroku deployment manifest file for apps that are not built via the container registry.

https://devcenter.heroku.com/articles/app-json-schema

Requirements for issue:

• Create a valid app.json.
• Add one of those "one click deploy" buttons in the README.md.

The previous project I worked on is a good example of how to do all these things: https://github.com/codeforboston/flagging

For our project we would just want the Postgres add-on, and a SECRET_KEY I think for now.

I got started on this, but it's not clear what you mean by "Add one of those "one-click deploy" buttons in the README.md"

This thing:

It's simple to add to a README.md. This works for any arbitrary repo with a valid app.json.

Closing as this approach is not compatible with a Docker/Heroku pairing.
