Docs: Install Kubeflow

Mon, 01 Jan 0001 00:00:00 +0000

This guide describes how to use the kfctl CLI to deploy Kubeflow 0.7 on an existing OpenShift 4.2 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 0.7 on OpenShift 4.2.

Clone the [opendatahub/manifests] (https://github.com/opendatahub-io/manifests) repository. This repository defaults to the v0.7.0-branch-openshift branch.
```
git clone https://github.com/opendatahub-io/manifests.git
cd manifests
```

Build the deployment configuration using the OpenShift KFDef file and local downloaded manifests.

At the time this document was written, Kubeflow issue #4678 prevents downloading the manifests during a build process. Update the manifest repo URI. Copy the KFDef file to the Kubeflow application directory. And finally build the configuration.

# update the manifest repo URI
sed -i 's#uri: .*#uri: '$PWD'#' ./kfdef/kfctl_openshift.yaml

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

Apply the generated deployment configuration.
```
kfctl apply --file=kfctl_openshift.yaml
```

Wait until all the pods are running.

The command below looks up the URL of Kubeflow user interface assigned by the OpenShift cluster. You can open the printed URL in your broser to access the Kubeflow user interface.
```
oc get routes -n istio-system istio-ingressgateway -o jsonpath='http://{.spec.host}/'
```
