Overview of this book

Kubernetes has continued to grow and achieve broad adoption across various industries, helping you to orchestrate and automate container deployments on a massive scale. This book will give you a complete understanding of Kubernetes and how to get a cluster up and running. You will develop an understanding of the installation and configuration process. The book will then focus on the core Kubernetes constructs such as pods, services, replica sets, replication controllers, and labels. You will also understand how cluster level networking is done in Kubernetes. The book will also show you how to manage deployments and perform updates with minimal downtime. Additionally, you will learn about operational aspects of Kubernetes such as monitoring and logging. Advanced concepts such as container security and cluster federation will also be covered. Finally, you will learn about the wider Kubernetes ecosystem with OCP, CoreOS, and Tectonic and explore the third-party extensions and tools that can be used with Kubernetes. By the end of the book, you will have a complete understanding of the Kubernetes platform and will start deploying applications on it.

Tectonic


Running Kubernetes on CoreOS is a great start, but you may find that you want a higher level of support. Enter Tectonic, the CoreOS enterprise offering for running Kubernetes with CoreOS. Tectonic uses many of the components we already discussed. CoreOS is the OS and both Docker and rkt runtimes are supported. In addition, Kubernetes, etcd, and flannel are packaged together to give a full stack of cluster orchestration. We discussed flannel briefly in Chapter 3, Networking, Load Balancers, and Ingress. It is an overlay network that uses a model similar to the native Kubernetes model, and it uses etcd as a backend.

Offering a support package similar to Red Hat, CoreOS also provides 24x7 support for the open-source software that Tectonic is built on. Tectonic also provides regular cluster updates and a nice dashboard with views for all the components of Kubernetes. CoreUpdate allows users to have more control of the automatic updates. In addition, it ships with modules for monitoring...
