Install Kubeflow on OpenShift

This guide describes how to use the kfctl CLI to deploy Kubeflow 1.3 on an existing OpenShift 4.x cluster.

Prerequisites

OpenShift 4 cluster

• You need to have access to an OpenShift 4 cluster as cluster-admin to be able to deploy Kubeflow.
• You can use Code Ready Containers (CRC) to run a local cluster, use try.openshift.com to create a new cluster or use an existing cluster.
• Install oc command-line tool to communicate with the cluster.

Code Ready Containers

If you are using Code Ready Containers, you need to make sure you have enough resources configured for the VM:

Recommended:

16 GB memory
6 CPU
45 GB disk space

Minimal:

10 GB memory
6 CPU
30 GB disk space (default for CRC)

Installing Kubeflow

Use the following steps to install Kubeflow 1.3 on OpenShift 4.x.

1. Download the example “kfdef” for Kubeflow 1.3 on Openshift from [kubeflow/manifests/distributions/kfdef] (https://raw.githubusercontent.com/opendatahub-io/manifests/v1.3-branch/distributions/kfdef/kfctl_openshift_v1.3.0.yaml).

2. Build the deployment configuration using the example OpenShift KFDef file.

   Create a directory and copy the KFDef file to it. And finally build the configuration.

   # set the Kubeflow application directory for this deployment, for example /opt/openshift-kfdef
   export KF_DIR=<path-to-kfdef>
   mkdir -p ${KF_DIR}
   cp kfctl_openshift_v1.3.0.yaml ${KF_DIR}
   
   # build deployment configuration
   cd ${KF_DIR}
   kfctl build --file=kfctl_openshift_v1.3.0.yaml
   

3. Apply the generated deployment configuration.

   kfctl apply --file=kfctl_openshift_v1.3.0.yaml
   

4. Wait until all the pods are running.

   $ oc get pods -n kubeflow

5. The command below looks up the URL of the Kubeflow user interface assigned by the OpenShift cluster. You can open the printed URL in your browser to access the Kubeflow user interface.

   oc get routes -n istio-system istio-ingressgateway -o jsonpath='http://{.spec.host}/'
