Cloud Native with Kubernetes

Harness Kubernetes' extensibility to deploy modern patterns and learn to effectively handle production issues

▶Book Description
Kubernetes is a modern cloud native container orchestration tool and one of the most popular open source projects worldwide. In addition to the technology being powerful and highly flexible, Kubernetes engineers are in high demand across the industry.

This book is a comprehensive guide to deploying, securing, and operating modern cloud native applications on Kubernetes. From the fundamentals to Kubernetes best practices, the book covers essential aspects of configuring applications. You'll even explore real-world techniques for running clusters in production, tips for setting up observability for cluster resources, and valuable troubleshooting techniques. Finally, you'll learn how to extend and customize Kubernetes, as well as gaining tips for deploying service meshes, serverless tooling, and more on your cluster.

By the end of this Kubernetes book, you'll be equipped with the tools you need to confidently run and extend modern applications on Kubernetes.

▶What You Will Learn
-Set up Kubernetes and configure its authentication
-Deploy your applications to Kubernetes
-Configure and provide storage to Kubernetes applications
-Expose Kubernetes applications outside the cluster
-Control where and how applications are run on Kubernetes
-Set up observability for Kubernetes
-Build a continuous integration and continuous deployment (CI/CD) pipeline for Kubernetes
-Extend Kubernetes with service meshes, serverless, and more

▶Key Features
-Build and run efficient cloud-native applications on Kubernetes using industry best practices
-Operate Kubernetes in a production environment, troubleshoot clusters, and address security concerns
-Deploy cutting-edge Kubernetes patterns such as service mesh and serverless to your cluster

▶Who This Book Is For
This book is for developers, architects, DevOps engineers, or anyone interested in developing and managing cloud-native applications. Those already running cloud applications and looking for a better way to manage their platform or others interested in a career change given the recent popularity of Kubernetes will also find this book helpful. Some familiarity with cloud computing, containers and DevOps is required, but no prior knowledge of building production applications using Kubernetes is needed to get started with this book.

▶What this book covers
- Chapter 1, Communicating with Kubernetes, introduces you to the concept of container orchestration and the fundamentals of how Kubernetes works. It also gives you the basic tools you need in order to communicate with and authenticate with a Kubernetes cluster.

- Chapter 2, Setting Up Your Kubernetes Cluster, walks you through creating a Kubernetes cluster in a few different popular ways, both on your local machine and on the cloud.

- Chapter 3, Running Application Containers on Kubernetes, introduces you to the most basic building block of running applications on Kubernetes – the Pod. We cover how to create a Pod, as well as the specifics of the Pod lifecycle.

- Chapter 4, Scaling and Deploying Your Application, reviews higher-level controllers, which allow the scaling and upgrading of multiple Pods of an application, including autoscaling.

- Chapter 5, Services and Ingress – Communicating with the Outside World, introduces several approaches to exposing applications running in a Kubernetes cluster to users on the outside.

- Chapter 6, Kubernetes Application Configuration, gives you the skills you need to provide configuration (including secure data) to applications running on Kubernetes.

- Chapter 7, Storage on Kubernetes, reviews methods and tools to provide persistent and non-persistent storage to applications running on Kubernetes.

- Chapter 8, Pod Placement Controls, introduces several different tools and strategies for controlling and influencing Pod placement on Kubernetes Nodes.

- Chapter 9, Observability on Kubernetes, covers multiple tenets of observability in the context of Kubernetes, including metrics, tracing, and logging.

- Chapter 10, Troubleshooting Kubernetes, reviews some key ways Kubernetes clusters can fail – as well as how to effectively triage issues on Kubernetes.

- Chapter 11, Template Code Generation and CI/CD on Kubernetes, introduces Kubernetes YAML templating tooling and some common patterns for CI/CD on Kubernetes.

- Chapter 12, Kubernetes Security and Compliance, covers the basics of security on Kubernetes, including some recent security issues with the Kubernetes project, and tooling for cluster and container security.

- Chapter 13, Extending Kubernetes with CRDs, introduces Custom Resource Definitions (CRDs) along with other ways to add custom functionality to Kubernetes, such as operators.

- Chapter 14, Service Meshes and Serverless, reviews some advanced patterns on Kubernetes, teaching you how to add a service mesh to your cluster and enable serverless workloads.

- Chapter 15, Stateful Workloads on Kubernetes, walks you through the specifics of running stateful workloads on Kubernetes, including a tutorial on running some powerful stateful applications from the ecosystem.
