Quick Recap

Key points

What you’ve learned in this chapter:

1. Building your own production-level Docker image with a Dockerfile.
2. Launching a container from that image in both production and development environments.
3. Using Docker Compose for easier development.
4. Auto-restarting a Node.js application when mounted files change.
5. Debugging an application running in a container.

In the next chapter, you will push the Docker image you have just created to Docker Hub … and discover why that could be useful.
