Overview

OpenShift Deep Dive: Automation, CI/CD, and Multi-Tenancy provides an authoritative exploration of the OpenShift platform, establishing a strong architectural foundation before advancing into specialized operational topics. The book dissects the integral relationship between Kubernetes and OpenShift, highlighting key extensions such as advanced networking, security frameworks, storage management, and operator-driven lifecycle automation. With a thorough examination of control plane internals, service mesh integration, and robust authentication and authorization systems, readers gain a holistic understanding of how OpenShift elevates enterprise Kubernetes environments. The journey continues with a focused deep dive into infrastructure automation, multi-tenancy, and workload orchestration. Readers are guided through best practices in deploying and managing OpenShift clusters using Terraform, Ansible, the OpenShift Machine API, and GitOps methodologies for configuration and policy management. Beyond the foundational elements, the book addresses the complexities of resource scheduling, workload isolation, quotas, and network segmentation, offering actionable strategies for ensuring performance, resilience, and fair allocation in multi-tenant environments. A significant portion of the book is dedicated to building and securing continuous integration and delivery (CI/CD) pipelines, leveraging OpenShift-native tools like Tekton, as well as industry-standard systems such as Jenkins and GitLab CI. Detailed guidance on GitOps workflows, secrets management, progressive delivery, software supply chain security, observability, and disaster recovery empowers practitioners to scale their operations with confidence and efficiency. Whether you're automating deployments, optimizing for high availability, or planning for multi-cluster growth, this comprehensive volume delivers the expertise needed for modern, enterprise-grade OpenShift operations.
