Installation

This section details how to set up and configure Model Registry on your Kubernetes cluster with Kubeflow.

Prerequisites

These are the minimal requirements to install Model Registry:

• Kubernetes >= 1.27
• Kustomize >= 5.0.3 (see more)

Installing Model Registry

Kubeflow Model registry may be installed as part of a Kubeflow Platform, or as a standalone component. The best option for you will depend on your specific requirements.

Installing on Kubeflow Platform

Kubeflow Model Registry is available as an opt-in alpha component in Kubeflow Platform 1.9+, see Installing Kubeflow to learn more about deploying the Kubeflow Platform.

If you have deployed the Kubeflow manifests, you may follow these instructions to deploy Model Registry; please raise any feedback on kubeflow/model-registry.

Standalone installation

If you want to install Model Registry separately from Kubeflow, or to get a later version of Model Registry, you can install the Model Registry manifests directly from the Model Registry repository.

By default, the manifests deploy the Model Registry in the kubeflow namespace; you must ensure the kubeflow namespace is available (for example: kubectl create namespace kubeflow) or modify the kustomization file to your desired namespace.

See the list of available versions on the GitHub releases of the kubeflow/model-registry repository. To install a specific release of the Model Registry, modify the following commands with the desired ref=<GIT_TAG>.

Run the following command to install the v0.2.3-alpha release of Model Registry:

kubectl apply -k "https://github.com/kubeflow/model-registry/manifests/kustomize/overlays/db?ref=v0.2.3-alpha"

If your Kubernetes cluster uses Istio, you MUST apply the Istio-compatibility manifests (e.g. when using a full Kubeflow Platform). However, these are NOT required for non-Istio clusters.

kubectl apply -k "https://github.com/kubeflow/model-registry/manifests/kustomize/options/istio?ref=v0.2.3-alpha"

Check Model Registry setup

You can check the status of the Model Registry deployment with your Kubernetes tooling, or for example with:

kubectl wait --for=condition=available -n kubeflow deployment/model-registry-deployment --timeout=1m
kubectl logs -n kubeflow deployment/model-registry-deployment

Optionally, you can also manually forward the REST API container port of Model Registry and interact with the REST API, for example with:

kubectl port-forward svc/model-registry-service -n kubeflow 8081:8080
# in another terminal:
curl -X 'GET' \
  'http://localhost:8081/api/model_registry/v1alpha3/registered_models?pageSize=100&orderBy=ID&sortOrder=DESC' \
  -H 'accept: application/json' | jq

If you are not receiving a 2xx response, it might be the case you are trying to consume a different version (v1alphaX) of the REST API than intended.

Perform the check from within a Notebook

To check the connection to the Model Registry from a Notebook instead, start a Terminal from the Notebook environment, then you can dry-run the connection with the following command:

curl model-registry-service.kubeflow.svc.cluster.local:8080/api/model_registry/v1alpha3/registered_models

or, alternatively, with the following command:

wget -nv -O- model-registry-service.kubeflow.svc.cluster.local:8080/api/model_registry/v1alpha3/registered_models

If the command executes without any error, you will get a JSON response from Model Registry, indicating the connection and request was successful.

You can use the same commands in a Jupyter Notebook cell by prefixing the command with ! (e.g.: ! curl ...).
