Cloud Native Infrastructure

By: Justin Garrison and Kris Nova

If you’re an engineer developing infrastructure or infrastructure management tools this book is for you. This book will help you understand the patterns, processes, and practices to create infrastructure that is intended to be run in a cloud environment. By having an understanding of how things should be, you can better know the application’s role and what should be consumed as external services.
Application engineers can also discover what services should be a part of their applications and which they can rely on from the underlying platform. Through this book they will also discover the shared responsibilities they have with the engineers writing applications to manage the infrastructure.
Systems Administrators who are looking to level up their skills and take a more prominent role in designing infrastructure and maintaining infrastructure in a cloud native way can learn from this book.
Do you run all of your infrastructure in a public cloud? This book will help you know when to consume cloud services and when to build your own abstractions or services.
Run a datacenter or on-premisis cloud? We will outline what modern applications expect from infrastructure and help you understand the necessary services to utilize your current investments.
This book is not a how-to and outside of giving implementation examples we’re not prescribing a specific product. It is probably too technical for managers, directors, and executives, but could be helpful depending on the involvement and technical expertiese of the person in that role.
Most of all, please read this book if you want to learn how infrastructure impacts business, and how you can create infrastructure that has proven to scale to the demanding needs of Internet sized applications. Even if you don’t have applications that require scaling to that size you will still be better able to provide value if your infrastructure is built with the patterns described here with flexibility and operability in mind.

DevOps with Kubernetes - Introduction to Kubernetes practices

By: Jami Kousa with the help of University of Helsinki’s Toska and numerous course attendees.

This course is an introductory course to Kubernetes with K3s and GKE. In this course, you will develop software with a microservice architecture that utilizes Kubernetes to serve software that scales and deploys automatically. And learn how to manage it all.
This course may be challenging as it expects that you
are familiar with containers
are able to independently develop web software
have knowledge of SQL databases
know basics of networking
As this course was written by a developer it offers an introduction into Kubernetes with the eyes of a developer. This course does not go into Kubernetes administration and there are other resources such as Kubernetes the hard way which offer a deep dive into how everything works, but course may work as a starting point.

Kubernetes Patterns: Reusable Elements for Designing Cloud-Native Applications

By: Bilgin Ibryam and Roland Huß

The way developers design, build, and run software has changed significantly with the evolution of microservices and containers. These modern architectures use new primitives that require a different set of practices than most developers, tech leads, and architects are accustomed to. With this focused guide, Bilgin Ibryam and Roland Huß from Red Hat provide common reusable elements, patterns, principles, and practices for designing and implementing cloud-native applications on Kubernetes.
Each pattern includes a description of the problem and a proposed solution with Kubernetes specifics. Many patterns are also backed by concrete code examples. This book is ideal for developers already familiar with basic Kubernetes concepts who want to learn common cloud-native patterns. You’ll learn about the following pattern categories:
Foundational patterns cover the core principles and practices for building container-based cloud-native applications.
Behavioral patterns explore finer-grained concepts for managing various types of container and platform interactions.
Structural patterns help you organize containers within a pod, the atom of the Kubernetes platform.
Configuration patterns provide insight into how application configurations can be handled in Kubernetes.
Advanced patterns cover more advanced topics such as extending the platform with operators.

Kubernetes in Action

By: Marko Lukša

Kubernetes in Action is a comprehensive guide to effectively developing and running applications in a Kubernetes environment. Before diving into Kubernetes, the book gives an overview of container technologies like Docker, including how to build containers, so that even readers who haven’t used these technologies before can get up and running.
Kubernetes is Greek for “helmsman,” your guide through unknown waters. The Kubernetes container orchestration system safely manages the structure and flow of a distributed application, organizing containers and services for maximum efficiency. Kubernetes serves as an operating system for your clusters, eliminating the need to factor the underlying network and server infrastructure into your designs.
Kubernetes in Action teaches you to use Kubernetes to deploy container-based distributed applications. You’ll start with an overview of Docker and Kubernetes before building your first Kubernetes cluster. You’ll gradually expand your initial application, adding features and deepening your knowledge of Kubernetes architecture and operation. As you navigate this comprehensive guide, you’ll explore high-value topics like monitoring, tuning, and scaling.

Kubernetes: Up and Running

By: Kelsey Hightower, Brendan Burns, and Joe Beda

Legend has it that Google deploys over two billion application containers a week. How’s that possible? Google revealed the secret through a project called Kubernetes, an open source cluster orchestrator (based on its internal Borg system) that radically simplifies the task of building, deploying, and maintaining scalable distributed systems in the cloud. This practical guide shows you how Kubernetes and container technology can help you achieve new levels of velocity, agility, reliability, and efficiency.
Authors Kelsey Hightower, Brendan Burns, and Joe Beda—who’ve worked on Kubernetes at Google and other organizatons—explain how this system fits into the lifecycle of a distributed application. You will learn how to use tools and APIs to automate scalable distributed systems, whether it is for online services, machine-learning applications, or a cluster of Raspberry Pi computers.

The Kubernetes Book

By: Nigel Poulton

Every page, and every example, updated to the latest versions of Kubernetes and the latest trends in the cloud-native ecosystem.
Containers have revolutionized the way build, share and run applications. But like all good things, they come with their own set of challenges. This is where Kubernetes enters the scene.
Kubernetes helps you deploy and manage containerized applications at scale. It abstracts the underlying infrastructure so that you don’t need to care whether you’re deploying your applications to Amazon Web Services, Microsoft Azure, or your own on-premises datacenter. With Kubernetes, you can develop your applications on your laptop, deploy to your chosen cloud platform, migrate to a different cloud platform, and even migrate to your private cloud at your on-premises datacenter.
The Kubernetes Book starts from the beginning and covers everything you need to know to be proficient with Kubernetes. It even includes two chapters dedicated to threat-modeling Kubernetes and real-world security.
You’ll learn:

Kubernetes architecture
How to build Kubernetes
How to deploy and manage applications on Kubernetes
How to secure Kubernetes
The meaning of terms such as; cloud-native, microservices, desired state, containerized, and more…
Finally, Kubernetes and cloud technologies are developing fast! That’s why this book will be updated at least once per year, meaning it’s always up-to-date with the latest versions of Kubernetes and the latest trends in the cloud-native ecosystem.

The following chapters describe the principle of controllers and detail how workload controllers work as well as the possibilities for configuring deployed applications.
You will also learn how to deploy a scalable and self-healing application, how pods are scheduled to nodes, how parts of the application can communicate, and how the application is discoverable from the outside. Next, you will cover security concerns describing the different authentication methods, the RBAC authorization mode, security contexts, network policies, and how to secure container images. You will also cover using persistent volumes for your containers to store long-term data, monitoring your clusters and applications and implementing design patterns for multi-container pods. The concluding chapters guide you through the upgrade of your deployed cluster.
After reading this book, you will have enough knowledge to deploy a complex application using a Kubernetes cluster and be ready for the certification exams.

Kubernetes The Hard Way

By: Kelsey Hightower

This tutorial walks you through setting up Kubernetes the hard way. This guide is not for people looking for a fully automated command to bring up a Kubernetes cluster.
Kubernetes The Hard Way is optimized for learning, which means taking the long route to ensure you understand each task required to bootstrap a Kubernetes cluster.
The results of this tutorial should not be viewed as production ready, and may receive limited support from the community, but don’t let that stop you from learning!

Kubernetes Operators: Automating the Container Orchestration Platform

By: Jason Dobies and Joshua Wood

Operators are a way of packaging, deploying, and managing Kubernetes applications. A Kubernetes application doesn’t just run on Kubernetes; it’s composed and managed in Kubernetes terms. Operators add application-specific operational knowledge to a Kubernetes cluster, making it easier to automate complex, stateful applications and to augment the platform. Operators can coordinate application upgrades seamlessly, react to failures automatically, and streamline repetitive maintenance like backups.
Think of Operators as site reliability engineers in software. They work by extending the Kubernetes control plane and API, helping systems integrators, cluster administrators, and application developers reliably deploy and manage key services and components. Using real-world examples, authors Jason Dobies and Joshua Wood demonstrate how to use Operators today and how to create Operators for your applications with the Operator Framework and SDK.
Learn how to establish a Kubernetes cluster and deploy an Operator
Examine a range of Operators from usage to implementation
Explore the three pillars of the Operator Framework: the Operator SDK, the Operator Lifecycle Manager, and Operator Metering
Build Operators from the ground up using the Operator SDK
Build, package, and run an Operator in development, testing, and production phases
Learn how to distribute your Operator for installation on Kubernetes clusters
