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?
Using heroku's new build manifest, you can use the Build API to deploy your docker apps. This means you can use git push to build a docker app. You can also use GitHub Sync, and Review Apps.
