Containerize a Single-Container Application

In this section, we’ll complete the following steps to containerize a simple Node.js app:

• Get the application code from GitHub
• Create the Dockerfile
• Containerize the app
• Run the app
• Test the app
• Look a bit closer

Get the application code

The application we’ll use is a simple Node.js web app that serves a web page on port 8080.

If you still need to clone the repo, run the following command to clone it. You’ll need git installed, and it will create a new directory called ddd-book.

For this course, we have already cloned the code in our playground, and it can be accessed in the ddd-book folder in the root directory.
