The DevOps 2.3 Toolkit

By: Viktor Farcic

Overview of this book

Building on The DevOps 2.0 Toolkit, The DevOps 2.1 Toolkit: Docker Swarm, and The DevOps 2.2 Toolkit: Self-Sufficient Docker Clusters, Viktor Farcic brings his latest exploration of the DevOps Toolkit as he takes you on a journey to explore the features of Kubernetes. The DevOps 2.3 Toolkit: Kubernetes is a book in the series that helps you build a full DevOps Toolkit. This book in the series looks at Kubernetes, the tool designed to, among other roles, make it easier in the creation and deployment of highly available and fault-tolerant applications at scale, with zero downtime. Within this book, Viktor will cover a wide range of emerging topics, including what exactly Kubernetes is, how to use both first and third-party add-ons for projects, and how to get the skills to be able to call yourself a “Kubernetes ninja.” Work with Viktor and dive into the creation and exploration of Kubernetes with a series of hands-on guides.

Everything we learned led us to Deployments. Pods must not be created directly, but through ReplicaSets which, similarly, must not be created directly, but through Deployments. They are the objects that allow us not only to create the ReplicaSets and Pods, but that can also be updated without producing any downtime (when applications are designed accordingly). We combined Deployments with Services so that Pods can communicate with each other, or can be accessed from outside a cluster. All in all, we have everything we need to release our services to production. That is not to say that we understand all the crucial aspects of Kubernetes. We're not even close to that point. But, we do have almost everything we need for running some types of applications in production. What we're missing is networking.
