PLATFORM ENGINEERING WITH CROSSPLANE

Build a self-service platform that developers trust using Crossplane v2, from first install to audited operations.

Many teams struggle with scattered scripts, slow tickets, and fragile handoffs. This book turns platform engineering into a concrete practice by treating infrastructure and service capabilities as stable APIs. You get clear contracts for developers, continuous reconciliation that fixes drift, and guardrails that satisfy auditors without slowing delivery.

Step by step, you install Crossplane, design opinionated platform APIs with XRDs and Compositions, wire identity per cloud with least privilege, ship OCI packages through GitOps, integrate a portal, and operate at scale with metrics, runbooks, and SLOs.

• Install Crossplane v2 cleanly and pick minimal provider families to keep CRDs lean
• Design reliable platform APIs with XRD schemas, defaults, validation, and descriptions
• Author composition pipelines using patch and transform, Go templating, and function modules
• Package and distribute configurations and functions as OCI artifacts with signing and SBOMs
• Set up secure cloud auth, IRSA on AWS, Workload Identity on GCP and Azure federated credentials
• Deliver secrets and connection details safely with StoreConfig targets and External Secrets
• Make GitOps work with Crossplane using Argo CD or Flux, waves, health checks, and readiness gates
• Expose resources and events in a Backstage portal, generate claims with Software Templates, and enforce permissions
• Observe controllers with actionable metrics, handle failure modes, and automate alerts and remediation
• Scale tenancy with namespaced managed resources, ProviderConfig per team, and multi control planes
• Test deeply with crossplane render, KUTTL or Chainsaw, and add conformance checks
• Migrate safely, v1 to v2 pipelines, adopt existing resources, and map Terraform modules to composites

This is a code-heavy guide with working YAML, Shell, HCL, JSON, and CI examples that you can drop into repos to stand up real environments.
