How to Deploy a Wagtail Gatsby Site

Carl: How do you deploy a Wagtail Gatsby site? Do you have Gatsby on Netlify and Wagtail on Heroku or what do you use for the API part? Currently, I'm using digital ocean and with my deploy, I couldn't get the Wagtail Netlify to work exactly yet. But yes, this point it is currently magic to me but that's a future plan of mine.
