class ResourcePreset

Reads the +app.kubernetes.io/size+ label from pod-bearing resources and injects CPU/memory requests and limits into every container.

The label on the resource is the input:

Kube::Cluster["Deployment"].new { metadata.labels = "app.kubernetes.io/size": "small" ... }

Register in the stack — no arguments needed:

stack do use Middleware::ResourcePreset end

Available sizes: nano, micro, small, medium, large, xlarge, 2xlarge. Limits are ~1.5x requests (following Bitnami conventions).
