How to handle a staging / production pipelin with App Platform ?

Hi,

I’m currently evaluating if App Platform can replace how we use Heroku today, and I’m wondering how one would handle a staging / release process ? On Heroku there is a “pipeline” feature that allows building a slug in “dev” or “staging”, launching it, and then passing the prebuilt slug in production, without rebuilding it.

How could it be done in App Platform? I cannot think of a better solution but to have two apps on app platform, plugged into different branches (lets say develop and master), but that would mean rebuilding the slug when going to production.

Thanks
