Quick Installation(v2)

disclaimer

Version 2.X represents an alpha release, exclusively accessible via the "fast" channel. Subsequent releases will transition to the "fast" channel once the new operator attains greater stability.

For installation steps of the old (version 1.X, stable), see quick installation of the 1.X version.

Pre-requisites

Below information is only appliable for Open Data Hub Operator v2.0.0 and forth release.

Installing Open Data Hub requires OpenShift Container Platform version 4.10+. All screenshots and instructions are from OpenShift 4.12. For the purposes of this quick start, we used try.openshift.com on AWS.

Tutorials will require an OpenShift cluster with a minimum of 16 CPUS and 32GB of memory across all OpenShift worker nodes.

Installing the New Open Data Hub Operator

The Open Data Hub operator is available for deployment in the OpenShift OperatorHub as a Community Operator. You can install it from the OpenShift web console by following the steps below:

  1. From the OpenShift web console, log in as a user with cluster-admin privileges. For a developer installation from try.openshift.com, the kubeadmin user will work. Log in to OpenShift

  2. On the lefthand bar, from Operators -> OperatorHub,

    • filter for Open Data Hub Operator.
    • select AI/Machine Learning and look for the icon for Open Data Hub Operator.

  3. Click Continue in the "Show community Operator" dialog if it pops out. Click the Install button to install the Open Data Hub operator. Install

  4. The subscription creation view will offer a few options including Update Channel, make sure the fast channel is selected. Click Install to deploy the opendatahub operator into the openshift-operators namespace. Select Channel

  5. To view the status of the Open Data Hub operator installation, find the Open Data Hub Operator under Operators -> Installed Operators. It might take a couple of minutes to show, but once the Status field displays Succeeded, you can proceed to create a DataScienceCluster instance Installed Operators

Create a DataScienceCluster instance

  1. Click on the Open Data Hub Operator from Installed Operators page to bring up the details for the version that is currently installed. Open Data Hub Operator

  2. Two ways to create DataScienceCluster instance:

    • Click Create DataScienceCluster button from the top warning dialog DataScienceCluster required(Create a DataScienceCluster instance to use this Operator.)
    • Click tab Data Science Cluster then click Create DataScienceCluster button

    They both lead to a new view called "Create DataScienceCluster". By default, namespace/project opendatahub is used to host all applications.

  3. In the view of "Create DataScienceCluster", user can create DataScienceCluster instance in two ways with components fields.

    • Form view: a. Fill in Name field b. In the components section, click > to expand the list of currently supported core components. Check the set of components enabled by default and tick/untick the box in each component section to tailor the selection. Create DSC2

    • YAML view: a. View the detail schema by expanding the right-hand sidebar Create DSC1 b. Read ODH Core components to get the full list of supported components.

  4. Click Create button to finalize creation process in seconds. DSC Status

  5. Verify the installation by viewing the project workload. Click Home then Projects, select "opendatahub" project, in the Workloads tab to view enabled compoenents. These should be running. Verify Status

Open Data Hub Dashboard

The data scientists and other users will most likely use the Open Data Hub features through Open Data Hub Dashboard. Its URL can be found in Menu > Networking > Routes, Project opendatahub, the Location colum of the odh-dashboard route.
