Overview of this book

Knowing how to use Rancher enables you to manage multiple clusters and applications without being locked into a vendor’s platform. This book will guide you through Rancher’s capabilities while deepening your understanding of Kubernetes and helping you to take your applications to a new level. The book begins by introducing you to Rancher and Kubernetes, helping you to learn and implement best practices. As you progress through the chapters, you’ll understand the strengths and limitations of Rancher and Kubernetes and discover all the different ways to deploy Rancher. You’ll also find out how to design and deploy Kubernetes clusters to match your requirements. The concluding chapters will show you how to set up a continuous integration and continuous deployment (CI/CD) pipeline for deploying applications into a Rancher cluster, along with covering supporting services such as image registries and Helm charts. By the end of this Kubernetes book, you’ll be able to confidently deploy your mission-critical production workloads on Rancher-managed Kubernetes clusters.

What an image repository is and the rules for architecting a solution

One of the critical things with containerization is the concept of images. An image is a read-only file that contains all the files, libraries, and executables that make up a container. Once you create a container image, you need to store it someplace where it will be available to download from your Kubernetes nodes. This place is called a registry, container registry, or image repository. For this chapter, we are going to call it an image repository. There are, of course, three main types of image repositories: Docker Hub, third-party, and self-hosted.

But before designing a solution, you should be able to answer the following questions:

  • Will this be an air-gapped environment, that is, do all images have to come from a registry we control?
  • Are all your images public, or will you be using a private repo?
  • What is your budget for both software and hardware?
  • Will multiple data centers/sites need...
