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.
