Next-Gen Unix, Storage & Infrastructure Operational Paradigms
Declarative Infrastructure with Crossplane
Crossplane turns a Kubernetes cluster into a universal control plane that provisions and reconciles cloud resources from declarative YAML. It unifies application and infrastructure lifecycle under one GitOps workflow, but it also concentrates power in the cluster and can propagate bad manifests quickly. Guardrails, composition, and careful RBAC are essential.
要点
- Define composite resources that hide cloud complexity behind simple, approved interfaces.
- Manage infrastructure through GitOps with review and automated policy checks.
- Scope provider credentials with least privilege and separate accounts per environment.
- Use composition functions to enforce standards like tagging, encryption, and sizing.
- Validate manifests with policy-as-code before they reach the control plane.
- Monitor reconciliation status and alert on stuck or failed resources.
- Keep a clear separation between platform team ownership and application team consumption.
- Test compositions in a sandbox cluster before promoting to production.
よくある質問
Is Crossplane better than Terraform?
They solve different problems; Crossplane fits Kubernetes-native, continuous reconciliation workflows.
What is the main risk?
A bad manifest reconciling continuously and recreating unwanted resources.
Do I need to know Kubernetes?
Yes, since Crossplane runs as a Kubernetes control plane extension.
How do I limit blast radius?
Use separate control planes per environment and strict RBAC on compositions.
