crossplane-control-plane

name	crossplane-control-plane
description	Crossplane universal control plane for cloud resource management via Kubernetes. Composite Resources (XR), Compositions, provider configuration, and managing AWS/GCP/Azure resources with kubectl. Sources: crossplane/crossplane (Apache-2.0).

/crossplane-control-plane

When to Use

• Provision cloud resources (S3 bucket, RDS, Cloud SQL) with the same kubectl workflow as K8s resources
• Unified control plane: one YAML API for both app and infrastructure lifecycle
• Composition: define organizational standards once, let teams create resources from templates
• Agent needs a database: agent requests a PostgreSQLInstance, Crossplane provisions it

Do NOT use for

• Terraform workflows (Crossplane is K8s-native; use Terraform for non-K8s environments)
• One-time resource creation (kubectl is simpler without controller overhead)
