Master OpenShift 4 with hands-on guidance from industry experts. Install, configure, deploy, and manage containerized applications at scale with real-world examples and best practices for enterprise production environments. Key Features Learn OpenShift 4 fundamentals and advanced concepts, including architecture, deployment, and operations Build, secure, and manage scalable containerized applications for enterprise environments Apply skills through expert-led tutorials, real-world projects, and hands-on labs for observability and more Book DescriptionOpenShift is a powerful enterprise Kubernetes platform that simplifies the development, deployment, and management of containerized applications. Learn OpenShift is a comprehensive, hands-on guide designed for architects, DevOps engineers, SREs, and system administrators who want to take OpenShift 4 from architecture to production deployment. Drawing on the experience of seasoned architects who’ve worked on some of the world’s largest OpenShift projects, this book covers both fundamentals and advanced scenarios rarely discussed elsewhere. You’ll explore OpenShift 4 internals, understand its architecture, master cluster installation and upgrades, and gain deep insights into managing applications, configuring security, application builds, observability, and service mesh. With practical examples and real-world guidance, you’ll confidently deploy OpenShift on bare metal, virtualization, and cloud environments, and learn how to extend, maintain, and operate clusters at scale. By the end of this book, you’ll be able to install, secure, and operate OpenShift 4 clusters in enterprise production environments, deploy containerized applications at scale, and troubleshoot real-world issues with confidence.What you will learn Understand the key differences between Kubernetes and OpenShift 4 Set up OpenShift clusters on cloud, on-prem, and virtualized platforms Secure and manage apps with projects, quotas, network policies, and SCCs Implement GitOps workflows and build applications Monitor and trace services with Service Mesh and observability tools Deploy advanced services such as Data Foundation and Windows Containers Extend OpenShift with custom Operators, upgrade clusters, and troubleshoot issues Who this book is forThis book is for DevOps engineers, architects, SREs, and sysadmins with a foundational understanding of Linux and Kubernetes who want to master OpenShift 4 in enterprise environments. Whether you're migrating from OpenShift 3 or starting from scratch, you’ll gain practical skills for real-world production deployments.

Gain hands-on experience of installing OpenShift Origin 3.9 in a production configuration and managing applications using the platform you builtKey FeaturesGain hands-on experience of working with Kubernetes and DockerLearn how to deploy and manage applications in OpenShiftGet a practical approach to managing applications on a cloud-based platformExplore multi-site and HA architectures of OpenShift for productionBook DescriptionDocker containers transform application delivery technologies to make them faster and more reproducible, and to reduce the amount of time wasted on configuration. Managing Docker containers in the multi-node or multi-datacenter environment is a big challenge, which is why container management platforms are required. OpenShift is a new generation of container management platforms built on top of both Docker and Kubernetes. It brings additional functionality to the table, something that is lacking in Kubernetes. This new functionality significantly helps software development teams to bring software development processes to a whole new level.In this book, we’ll start by explaining the container architecture, Docker, and CRI-O overviews. Then, we'll look at container orchestration and Kubernetes. We’ll cover OpenShift installation, and its basic and advanced components. Moving on, we’ll deep dive into concepts such as deploying application OpenShift. You’ll learn how to set up an end-to-end delivery pipeline while working with applications in OpenShift as a developer or DevOps. Finally, you’ll discover how to properly design OpenShift in production environments.This book gives you hands-on experience of designing, building, and operating OpenShift Origin 3.9, as well as building new applications or migrating existing applications to OpenShift.What you will learnUnderstand the core concepts behind containers and container orchestration toolsUnderstand Docker, Kubernetes, and OpenShift, and their relation to CRI-OInstall and work with Kubernetes and OpenShiftUnderstand how to work with persistent storage in OpenShiftUnderstand basic and advanced components of OpenShift, including security and networkingManage deployment strategies and application’s migration in OpenShiftUnderstand and design OpenShift high availability Who this book is forThe book is for system administrators, DevOps engineers, solutions architects, or any stakeholder who wants to understand the concept and business value of OpenShift.
