Basic Binding

This example shows the simplest PoolOnly flow.

kleym-operator currently consumes only a small slice of the referenced Gateway API Inference Extension (GAIE) objects:

  • from the pool: spec.selector

Your installed GAIE version may require additional fields on that object. The snippets below focus on the fields that matter to kleym-operator. For full GAIE schema details, see InferencePool. Reference docs: SPIFFE overview, SPIRE concepts, and ClusterSPIFFEID CRD.

Input 

apiVersion: inference.networking.k8s.io/v1
kind: InferencePool
metadata:
  name: pool-a
  namespace: default
spec:
  selector:
    matchLabels:
      app: model-server
apiVersion: kleym.sonda.red/v1alpha1
kind: InferenceIdentityBinding
metadata:
  name: pool-a
  namespace: default
spec:
  poolRef:
    name: pool-a
  serviceAccountName: inference-sa
  mode: PoolOnly

Expected Outcome

The binding should reconcile to a managed ClusterSPIFFEID with:

  • SPIFFE ID spiffe://kleym.sonda.red/ns/default/pool/pool-a
  • a pod selector equivalent to matchLabels.app=model-server
  • workload selectors including:
    • k8s:ns:default
    • k8s:sa:inference-sa
    • k8s:pod-label:app:model-server

The generated ClusterSPIFFEID name is deterministic but includes a hash suffix, so the example below focuses on the meaningful fields:

apiVersion: spire.spiffe.io/v1alpha1
kind: ClusterSPIFFEID
metadata:
  labels:
    kleym.sonda.red/managed-by: kleym
    kleym.sonda.red/binding-name: pool-a
    kleym.sonda.red/binding-namespace: default
spec:
  spiffeIDTemplate: spiffe://kleym.sonda.red/ns/default/pool/pool-a
  podSelector:
    matchLabels:
      app: model-server
  workloadSelectorTemplates:
    - k8s:ns:default
    - k8s:pod-label:app:model-server
    - k8s:sa:inference-sa

The binding status should report:

  • Ready=True
  • Conflict=False
  • InvalidRef=False
  • UnsafeSelector=False
  • RenderFailure=False
