Getting Started with Kubernetes - Third Edition

By: Jonathan Baier, Jesse White

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. Based on the recent release of Kubernetes 1.12, Getting Started with Kubernetes gives you a complete understanding of how to install a Kubernetes cluster. The book focuses on core Kubernetes constructs, such as pods, services, replica sets, replication controllers, and labels. You will understand cluster-level networking in Kubernetes, and learn to set up external access to applications running in the cluster. As you make your way through the book, you'll understand how to manage deployments and perform updates with minimal downtime. In addition to this, you will explore operational aspects of Kubernetes , such as monitoring and logging, later moving on to advanced concepts such as container security and cluster federation. You'll get to grips with integrating your build pipeline and deployments within a Kubernetes cluster, and be able to understand and interact with open source projects. In the concluding chapters, you'll orchestrate updates behind the scenes, avoid downtime on your cluster, and deal with underlying cloud provider instability within your cluster. By the end of this book, you'll have a complete understanding of the Kubernetes platform and will start deploying applications on it.

True multi-cloud


This is an exciting space to watch. As it grows, it gives us a really good start to doing multi-cloud implementations and providing redundancy across regions, data centers, and even cloud providers. 

While Kubernetes does provide an easy and exciting path to multi-cloud infrastructure, it's important to note that production multi-cloud requires much more than distributed deployments. A full set of capabilities from logging and monitoring to compliance and host-hardening, there is much to manage in a multi-provider setup. 

True multi-cloud adoption will require a well-planned architecture, and Kubernetes takes a big step forward in pursuing this goal.

 

Getting to multi-cloud

In this exercise, we're going to unite two clusters using Istio's multi-cloud feature. Normally, we'd create two clusters from scratch, across two CSPs, but for the purposes of exploring one single isolated concept at a time, we're going to use the GKE to spin up our clusters, so we can focus on the inner...
