Summary: Containerization

Recap

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

We used Docker to containerize the app and push 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 having built the image, we practiced using the docker push command in order to push it to the DockerHub container registry.
