Open Data Hub Operator

Introduction

The Open Data Hub operator is responsible for managing the deployment and lifecycle of ODH Component manifests from either odh-manifests or different component repos under opendatahub-io orgnization using the KfDef Custom Resource. The focus is on supporting the ODH Core stack in the OpenShift clusters.

NOTE: The Open Data Hub operator was originally a downstream project of the kfctl operator but has diverged from the original functionality after the Kubeflow community deprecated the use of kfctl for deployment in favor of kustomize. kfctl cli is no longer a maintained or supported tool for parsing or processing the kfdef custom resource.

Usage

Installation

The latest version of operator can be installed from the community-operators catalog on OperatorHub. It can also be build and installed from source manually, see the Developer guide for further instructions.

Developer Guide

Pre-requisites

• Go version go1.18.4
• operator-sdk version can be updated to v1.24.1

Build Image

• Custom operator image can be built using your local repository

  make image -e IMG=quay.io/<username>/opendatahub-operator:<custom-tag>

  The default image used is quay.io/opendatahub/opendatahub-operator:dev-<VERSION>

• Once the image is create, the operator can be deployed either directly, or through OLM. For each deployment method a kubeconfig should be exported

  export KUBECONFIG=<path to kubeconfig>

Deployment

Deploying operator locally

• Define operator namespace

  export OPERATOR_NAMESPACE=<namespace-to-install-operator>

• Deploy the created image in your cluster using following command:

  make deploy -e IMG=quay.io/<username>/opendatahub-operator:<custom-tag>

• To remove resources created during installation use:

  make undeploy

Deploying operator using OLM

• Define operator namespace

  export OPERATOR_NAMESPACE=<namespace-to-install-operator>

• To create a new bundle, run following command:

  make bundle
  

  Note : Skip the above step if you want to run the existing operator bundle.

• Build Bundle Image:

  make bundle-build bundle-push BUNDLE_IMG=quay.io/<username>/opendatahub-operator-bundle:<VERSION>

• Run the Bundle on a cluster:

  operator-sdk run bundle quay.io/<username>/opendatahub-operator-bundle:<VERSION> --namespace $OPERATOR_NAMESPACE
  

Example KfDefs

When the operator is installed sucessfully in the cluster, a user can make use of following KfDefs to install Open Data Hub components:

• KfDef for Core Components

Do condier most of the components in odh-core.yaml might point to a bunch of out-of-date manifests, ensure to modify to the correct source component repo and branch.

Run e2e Tests

A user can run the e2e tests in the same namespace as the operator. To deploy opendatahub-operator refer to this section. The following environment variables must be set when running locally:

export KUBECONFIG=/path/to/kubeconfig
export OPERATOR_NAMESPACE=<namespace-of-operator>

Once the above variables are set, run the following:

make e2e-test

Additional flags that can be passed to e2e-tests by setting up E2E_TEST_FLAGS variable. Following table lists all the available flags to run the tests:

Flag	Description	Default value
--skip-deletion	To skip running of kfdef-deletion test that includes deleting KfDef resources. Assign this variable to true to skip KfDef deletion.	false

Example command to run full test suite in a custom namespace, skipping the test for KfDef deletion.

make e2e-test -e OPERATOR_NAMESPACE=<YOUR_NAMESPACE> -e E2E_TEST_FLAGS="--skip-deletion=true"
