Containerize a Single-Container Application

The rest of this chapter walks through the process of containerizing a simple Node.js web app.

We’ll complete the following high-level steps:

• Clone the repo to get the app code
• Inspect the Dockerfile
• Containerize the app
• Run the app
• Test the app
• Look a bit closer
• Move to production with Multi-Stage Builds
• A few best practices

The example in this chapter is of a single-container app.

Getting the application code

The application used in this example is available on GitHub.

Clone the sample app from GitHub.

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