Cluster API (CAPI)
"Cluster API (CAPI): Managing Kubernetes Clusters Like Applications" Kubernetes clusters have become critical infrastructure—and also a recurring operational burden. This book is for experienced platform engineers, SREs, and Kubernetes operators who want to manage clusters with the same disciplined, API-driven workflows they use for applications. Instead of scripts and one-off runbooks, you’ll learn to treat clusters as declarative objects, reconciled continuously by controllers, with clear ownership graphs and predictable lifecycle behavior. You’ll build a precise mental model of CAPI’s architecture: management vs. workload clusters, provider responsibilities, and the provider contract that enables portability. From there, the book dives deep into clusterctl installation and upgrade safety, core API objects (Cluster, Machine, MachineDeployment), and kubeadm-based providers for bootstrapping and control-plane management. You’ll come away able to create, scale, upgrade, remediate, and delete clusters reliably—while reading conditions, events, and logs as a coherent reconciliation story across bootstrap, control plane, and infrastructure layers. Practical, operator-grade chapters cover reproducible templates and variables, fleet consistency with ClusterClass and managed topologies, add-ons via ClusterResourceSet, and advanced operations like pivoting with clusterctl move. Expect thorough trade-off analysis, failure modes, and version/compatibility guidance throughout, assuming comfort with Kubernetes CRDs/controllers, RBAC, and multi-cluster operations.
Fundamentals of DevOps and Software Delivery
Author: Yevgeniy Brikman
language: en
Publisher: "O'Reilly Media, Inc."
Release Date: 2025-05-20
This book is a guide to DevOps and software delivery: that is, a guide to the numerous tools and techniques that are required to take that application code and run it and maintain it in production, where it can generate value for your users and your company on an ongoing basis. This includes going through all the modern practices for deploying applications and microservices to the cloud, managing your infrastructure as code, automating your software delivery lifecycle in a CI/CD pipeline, configuring networking, setting up data stores, and hooking up monitoring.

Learn how to deploy and test Linux-based Docker containers with the help of real-world use cases Key FeaturesUnderstand how to make a deployment workflow run smoothly with Docker containersLearn Docker and DevOps concepts such as continuous integration and continuous deployment (CI/CD)Gain insights into using various Docker tools and librariesBook Description Docker is the de facto standard for containerizing apps, and with an increasing number of software projects migrating to containers, it is crucial for engineers and DevOps teams to understand how to build, deploy, and secure Docker environments effectively. Docker for Developers will help you understand Docker containers from scratch while taking you through best practices and showing you how to address security concerns. Starting with an introduction to Docker, you'll learn how to use containers and VirtualBox for development. You'll explore how containers work and develop projects within them after you've explored different ways to deploy and run containers. The book will also show you how to use Docker containers in production in both single-host set-ups and in clusters and deploy them using Jenkins, Kubernetes, and Spinnaker. As you advance, you'll get to grips with monitoring, securing, and scaling Docker using tools such as Prometheus and Grafana. Later, you'll be able to deploy Docker containers to a variety of environments, including the cloud-native Amazon Elastic Kubernetes Service (Amazon EKS), before finally delving into Docker security concepts and best practices. By the end of the Docker book, you'll be able to not only work in a container-driven environment confidently but also use Docker for both new and existing projects. What you will learnGet up to speed with creating containers and understand how they workPackage and deploy your containers to a variety of platformsWork with containers in the cloud and on the Kubernetes platformDeploy and then monitor the health and logs of running containersExplore best practices for working with containers from a security perspectiveBecome familiar with scanning containers and using third-party security tools and librariesWho this book is for If you're a software engineer new to containerization or a DevOps engineer responsible for deploying Docker containers in the cloud and building DevOps pipelines for container-based projects, you'll find this book useful. This Docker containers book is also a handy reference guide for anyone working with a Docker-based DevOps ecosystem or interested in understanding the security implications and best practices for working in container-driven environments.
