CROSSPLANE: THE KUBERNETES ALTERNATIVE TO TERRAFORM: MANAGE MULTI-CLOUD INFRASTRUCTURE WITH DECLARATIVE KUBERNETES RESOURCES. GITOPS WORKFLOWS, PLATFORM ENGINEERING, AND PRODUCTION OPERATIONS - Softcover

Inhaltsangabe

Build a reliable multi-cloud platform where infrastructure reconciles itself.

Many teams ship Terraform plans but still fight drift, slow handoffs, and fragile state. If you already run Kubernetes, there is a better way. This book shows how to run infrastructure as Kubernetes resources so changes flow through Git, reconcile continuously, and stay safe for multi-tenant teams.

You will design product-grade APIs on Crossplane, deliver them with Argo CD or Flux, secure cloud access without static keys, and operate everything with clear signals for upgrades, rollbacks, and recovery.

• Compare plan and apply workflows with continuous reconciliation and decide where each fits
• Design clean XRDs and claims, version schemas, and publish stable connection secrets
• Author compositions with patches and transforms, then add function pipelines in YAML Python KCL or Go
• Build a GitOps path with Argo CD and Flux including sync waves health checks and policy gates
• Set up identity the safer way, AWS IRSA, GCP Workload Identity Federation, and Azure Workload Identity
• Centralize secret delivery with External Secrets Operator and cloud secret stores
• Run multi tenancy with namespaced claims per-namespace ProviderConfig isolation and RBAC
• Add guardrails with Gatekeeper or Kyverno and validate changes in CI with crossplane render
• Migrate from Terraform, inventory and import with observe only policies and bridge modules with provider terraform
• Upgrade safely with package revision activation and roll back with Composition Revisions
• Back up and restore clusters with Velero including CRDs XRs and provider state reattachment
• Operate day two tasks with Operations and CronOperation for rotation backups and maintenance windows
• Watch the right metrics, conditions and events for troubleshooting, tune reconcile rates and backoff, size and shard controllers
• Capstone, ship one product API that spans AWS and GCP with network and database plus an incident drill for rate limit storms

This is a code-heavy guide with working manifests and controller configurations that translate directly into real clusters.
