What better motivation to start adopting a technology than the need to completely replace the alternative. From a world driven on limited resources like gas, coal, and oil to wind, hydro, nuclear, geothermal, and solar… we find ourselves, as a species, evolving past a first generation we envisioned as abundant, but turned sparse. Adopting IPv6 networking is another version of this same story.

Kubernetes or K8s is an open-source production-grade container orchestration system for automating, scaling, and managing containerized applications. A container is a lightweight, standalone, executable ready-to-run software package that contains everything needed to run an application. It includes the runtime, code, libraries, systems tools, and default values for any essential settings.

You'll often hear the term "containers" used to refer to the entire landscape of self-contained software packages: this includes tools like Docker and Kubernetes, platforms like Amazon Elastic Container Service (ECS), and even the process of building these packages. But there's an even more important layer that often gets overlooked, and that's container images.
