Summary

Starting from the very primitive elements of Linux container to Docker tool stacks, we went through every aspect of containerizing an application, including packing and running a Docker container, writing a Dockerfile for code-based immutable deployment, and manipulating multi-containers with Docker Compose. However, our abilities gained in this chapter only allow us to run and connect containers within the same host, which limits the possibility to build larger applications. As such, in the next chapter, we'll meet Kubernetes, unleashing the power of Container beyond the limits of scale.
