Seldon Core Serving

Seldon Core comes installed with Kubeflow. The Seldon Core documentation site provides full documentation for running Seldon Core inference.

If you have a saved model in a PersistentVolume (PV), Google Cloud Storage bucket or Amazon S3 Storage you can use one of the prepackaged model servers provided by Seldon Core.

Seldon Core also provides language specific model wrappers to wrap your inference code for it to run in Seldon Core.

Kubeflow specifics

You need to ensure the namespace where your models will be served has:

• An Istio gateway named kubeflow-gateway
• A label set as serving.kubeflow.org/inferenceservice=enabled

The following example applies the label my-namespace to the namespace for serving:

kubectl label namespace my-namespace serving.kubeflow.org/inferenceservice=enabled

Create a gateway called kubeflow-gateway in namespace my-namespace:

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: kubeflow-gateway
  namespace: my-namespace
spec:
  selector:
    istio: ingressgateway
  servers:
  - hosts:
    - '*'
    port:
      name: http
      number: 80
      protocol: HTTP

Save the above resource and apply it with kubectl.

Examples

Seldon provides a large set of example notebooks showing how to run inference code for a wide range of machine learning toolkits.
