<p>I would like to create review apps for my open source application which already has a docker file.Is there any way where I could write an app.json file to deploy a Docker container for new pull requests for review apps?
or is there any way to use heroku container registry and runtime in review apps?</p>

<p>Using heroku's new <a href="https://devcenter.heroku.com/articles/heroku-yml-build-manifest" rel="nofollow noreferrer">build manifest</a>, you can use the Build API to deploy your docker apps.
This means you can use <code>git push</code> to build a docker app. You can also use GitHub Sync, and Review Apps.</p>
