Verify the kro capability

prepare-environment enabled the kro capability on the cluster. Confirm it's ACTIVE and that kro's CRDs are registered before applying anything.

Inspect the capability resource directly:

~$aws eks describe-capability \

--cluster-name $EKS_CLUSTER_AUTO_NAME \

--capability-name $EKS_CAP_KRO_CAPABILITY \

--query 'capability.status' --output text

ACTIVE

A capability transitions through CREATING → ACTIVE. If the status is anything else, wait a moment and re-run.

Check that kro's ResourceGraphDefinition CRD is registered:

~$kubectl get crd resourcegraphdefinitions.kro.run \

-o jsonpath='{.spec.names.kind}{"\n"}'

ResourceGraphDefinition

~$kubectl api-resources --api-group=kro.run

NAME                       SHORTNAMES   APIVERSION         NAMESPACED   KIND

resourcegraphdefinitions   rgd          kro.run/v1alpha1   false        ResourceGraphDefinition

備考

The ResourceGraphDefinition CRD is cluster-scoped (NAMESPACED: false). RGDs you create later are always cluster-wide. The instances of those RGDs — for example a CartsStack resource — are namespaced, because they own resources in a specific namespace.

With the capability ACTIVE and the CRD in place, we're ready to define our first RGD.
