Crossplane Step by Step for Platform Engineering: A Practical Guide to Building Internal Developer Platforms with Compositions, GitOps, Kubernetes, Policy, and Multi-Cloud Infrastructure - Tapa blanda

Sinopsis

Crossplane feels powerful—but getting from scattered YAML examples to a platform you can actually understand, build, and operate can feel overwhelming.

Crossplane Step by Step for Platform Engineering turns that complexity into a clear, practical learning path.

You do not need previous Crossplane experience. Instead of throwing advanced concepts at you all at once, this book introduces providers, managed resources, reconciliation, platform APIs, Compositions, GitOps, policy, multi-cloud infrastructure, and production operations in manageable stages.

You will build one continuous project—the Atlas Application Platform—so every chapter connects to what came before. Commands are followed by verification, longer configurations are broken into smaller working steps, and practical exercises help you learn by doing.

Mistakes are treated as part of the process. A provider may fail to authenticate. A Composition may produce the wrong resource. A policy may reject a request. Rather than hiding these moments, the book shows you how to inspect conditions, events, logs, and resource state so problems become understandable—and every successful reconciliation becomes a meaningful win.

• Step-by-step Crossplane learning with a continuous real-world platform project
• Practical coverage of Kubernetes-based infrastructure automation
• Developer-facing platform APIs with XRDs, Compositions, and Functions
• Self-service networking, storage, PostgreSQL, and Kubernetes resources
• GitOps delivery with Argo CD
• Security, RBAC, least privilege, policy, and governance with Kyverno
• AWS and Azure multi-cloud platform design
• Production troubleshooting, upgrades, recovery, observability, and maintenance
• Practical exercises, command references, checklists, and cleanup guidance

You will learn how to install and operate Crossplane, work with providers and managed resources, design stable platform APIs, build reusable Compositions, create self-service environments, manage infrastructure through GitOps, enforce security guardrails, implement multi-cloud backends, diagnose failures, manage upgrades, and operate a platform safely in production.

This book is ideal for:

• Readers new to Crossplane
• DevOps and cloud engineers
• Platform engineers
• Kubernetes practitioners
• Infrastructure-as-code users
• Developers moving toward internal developer platforms
• Self-learners who prefer practical, structured technical guidance

Basic familiarity with Kubernetes, Git, cloud infrastructure, and infrastructure-as-code concepts will make the hands-on exercises easier to follow.
