Recap

In this chapter, we learned that a containerized app is just a regular one built and packaged as a container image.

We used Docker to containerize the app and upload it to Docker Hub. Along the way, we learned that a Dockerfile is a list of instructions telling Docker how to containerize an app. Next, we learned how to build an image using the docker build command. After building the image, we practiced using the docker push command to push it to the Docker Hub container registry.
