In this chapter, you learned how to dockerize your application using a normal Dockerfile and a multi-stage build.

Furthermore, I have shown you how to set up an exemplary continuous deployment workflow using CircleCI and Heroku. You can replace the deployment process with a more complex setup by using AWS, but continue using our Docker image.

Having read this chapter, you have learned everything from developing a complete application to deploying it to a production environment. Your application should now be running on Heroku.
