Crossplane: The Kubernetes Alternative to Terraform: Manage Multi-Cloud Infrastructure with Declarative Kubernetes Resources. Gitops Workflows, Platfo

By: Rao, Anik

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 fitsDesign clean XRDs and claims, version schemas, and publish stable connection secretsAuthor compositions with patches and transforms, then add function pipelines in YAML Python KCL or GoBuild a GitOps path with Argo CD and Flux including sync waves health checks and policy gatesSet up identity the safer way, AWS IRSA, GCP Workload Identity Federation, and Azure Workload IdentityCentralize secret delivery with External Secrets Operator and cloud secret storesRun multi tenancy with namespaced claims per-namespace ProviderConfig isolation and RBACAdd guardrails with Gatekeeper or Kyverno and validate changes in CI with crossplane renderMigrate from Terraform, inventory and import with observe only policies and bridge modules with provider terraformUpgrade safely with package revision activation and roll back with Composition RevisionsBack up and restore clusters with Velero including CRDs XRs and provider state reattachmentOperate day two tasks with Operations and CronOperation for rotation backups and maintenance windowsWatch the right metrics, conditions and events for troubleshooting, tune reconcile rates and backoff, size and shard controllersCapstone, 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.
