In our first three installments in this series, we learned what Kubernetes is, why it's a good choice for your datacenter, and how it was descended from the secret Google Borg project. Now we're going to learn what makes up a Kubernetes cluster. A Kubernetes cluster is made of a master node and a set of worker nodes. In a production environment these run in a distributed setup on multiple nodes. For testing purposes, all the components can run on the same node (physical or virtual) by using minikube.

New tools like musl, toybox, and Clang are offering new techniques for shrinking the Linux kernel, file-system, and user space for IoT.
