Argo CD in Practice
Build CD pipelines following GitOps principles like declarative and immutable changes stored in version control, all continuously reconciled by Argo CD, and minimize the failure of deployments. Purchase of the print or Kindle book includes a free eBook in the PDF format. Key FeaturesDiscover how to apply GitOps principles to build real-world CD pipelinesUnderstand Argo CD components and how they work together to reconcile cloud native applicationsLearn to run Argo CD in production with declarative config changes, security, observability, disaster recovery, and moreBook Description GitOps follows the practices of infrastructure as code (IaC), allowing developers to use their day-to-day tools and practices such as source control and pull requests to manage apps. With this book, you'll understand how to apply GitOps bootstrap clusters in a repeatable manner, build CD pipelines for cloud-native apps running on Kubernetes, and minimize the failure of deployments. You'll start by installing Argo CD in a cluster, setting up user access using single sign-on, performing declarative configuration changes, and enabling observability and disaster recovery. Once you have a production-ready setup of Argo CD, you'll explore how CD pipelines can be built using the pull method, how that increases security, and how the reconciliation process occurs when multi-cluster scenarios are involved. Next, you'll go through the common troubleshooting scenarios, from installation to day-to-day operations, and learn how performance can be improved. Later, you'll explore the tools that can be used to parse the YAML you write for deploying apps. You can then check if it is valid for new versions of Kubernetes, verify if it has any security or compliance misconfigurations, and that it follows the best practices for cloud-native apps running on Kubernetes. By the end of this book, you'll be able to build a real-world CD pipeline using Argo CD. What you will learnUnderstand GitOps principles and how they relate to IaCDiscover how Argo CD lays the foundation for reconciling Git state with the cluster stateRun Argo CD in production with an emphasis on reliability and troubleshootingBootstrap Kubernetes clusters with essential utilities following the GitOps approachSet up a CD pipeline and minimize the failure of deploymentsExplore ways to verify and validate the YAML you put together when working with KubernetesUnderstand the democratization of GitOps and how the GitOps engine will enable its further adoptionWho this book is for If you're a software developer, DevOps engineer, or SRE who is responsible for building CD pipelines for projects running on Kubernetes and wants to advance in your career, this book is for you. Basic knowledge of Kubernetes, Helm, or Kustomize and CD pipelines will help you to get the most out of this book.
Practical Istio
Istio is a powerful service mesh technology that enhances the security, observability, and traffic management of microservices within cloud-native architectures. As organizations increasingly adopt microservices, managing the complexity of service interactions becomes critical. This book is designed to help professionals navigate these complexities by providing a deep understanding of Istio, empowering them to leverage their full potential in building resilient, scalable, and secure service infrastructures. Practical Istio offers a comprehensive journey through the service mesh, beginning with an introduction to its architecture and fundamental concepts. Readers will delve into advanced topics such as traffic management, security enforcement, and observability, gaining insights into how to implement and optimize Istio in real-world scenarios. Each chapter is crafted to provide practical guidance, including detailed explanations of Istio’s key components, like 'Istiod' and 'Envoy', hands-on examples for managing production grade deployments, and strategies for integrating Istio with CI/CD pipelines. The book also covers emerging trends and future directions of service mesh technology, ensuring readers stay ahead of the curve. By the end of this book, readers will be equipped with the knowledge and skills needed to implement Istio in production environments.

Open Policy Agent Rego Language in Practice
"Open Policy Agent Rego Language in Practice" Open Policy Agent Rego Language in Practice is a comprehensive guide for engineers, architects, and security professionals seeking mastery over policy-as-code in modern, cloud-native environments. Beginning with foundational concepts, the book delivers clear explanations of why and how policies are codified, the underlying architecture of OPA, and the essential features of the Rego language. Readers are guided through policy lifecycles, secure policy authoring, and the intricate considerations necessary to minimize risk while enabling scalable policy enforcement across complex systems. Delving deep into the Rego language, the book explores advanced syntax, semantics, and best practices for policy modeling, modularity, and abstraction. Through hands-on chapters, it addresses robust techniques for designing declarative, maintainable policies, managing data inputs, and composing sophisticated policy chains—all while fostering adaptability to evolving requirements. Detailed discussions on performance engineering, scalability, and error diagnostics further equip practitioners to deploy OPA at scale, supporting high-traffic microservices, data-centric workloads, and cross-cloud governance. The later sections transition seamlessly from technical mastery to practitioner assurance and applied security. Subjects such as policy testing, auditing, and formal verification are paired with real-world case studies covering fine-grained authorization, infrastructure security, and multi-cloud strategies. Rounding out the guide, readers are introduced to the OPA ecosystem, industry best practices, and the latest research directions in policy language evolution, formal assurance, and AI-driven governance. This book stands as an authoritative reference for harnessing the power and versatility of OPA and Rego in today’s dynamic infrastructure landscape.
