Starting from the very primitive elements of Linux containers and 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 multiple containers with Docker compose. However, the abilities we gained in this chapter only allow us to run and connect containers within the same host, which limits our ability to build larger applications.
In Chapter 3, Getting Started with Kubernetes, we'll meet Kubernetes, unleashing the power of containers beyond the limits of scale.
