A Heroku account and the Heroku CLI is needed to deploy this application to Heroku. Docker is also required.

Log in to container registry

$ heroku container:login

If you want to create a new Heroku app to deploy to, navigate to the app’s directory and create a Heroku app:

$ heroku create

Alternatively, if there is already a Heroku app you want to add this to, add the remote to the repository:

$ heroku git:remote -a your-app-name

Build the image and push to Container Registry:

$ heroku container:push web

Then release the image to your app:

$ heroku container:release web
