Installation

Pre-requisites

To install Kubeflow 0.7 on OpenShift 4.2 the following are the prerequisites:
1.Code Ready Container (CRC): A CRC-generated OpenShift cluster that with the following specifications: Recommended:
16GB memory
6 cpu
5G disk space
Minimum:
10GB memory
6 cpu
30G disk space (default for CRC)

NOTE: At the minimum specs, the CRC OpenShift cluster may be unresponsive for ~20mins while Kubeflow components are being deployed.
When installing Kubeflow on a CRC cluster, there is an extra overlay (named crc) to enable the metadata component in kfctl_openshift.yaml. It is commented out by default. Uncomment to enable it.

OR
OpenShift 4.2: An available OpenShift 4.2 cluster or you can try a cluster on try.openshift.com

2.kfctl: The installation tool kfctl is needed to install/uninstall Kubeflow. Download the tool from github, the version 0.7.0 is required for the installation.

Install Kubeflow with Istio Enabled

To install Kubeflow 0.7 on OpenShift 4.2 please follow the steps below:

  1. Clone the opendatahub-manifests fork repo which defaults to the branch v0.7.0-branch-openshift
    git clone https://github.com/opendatahub-io/manifests.git cd manifests
  2. Install using the Openshift configuration file and local downloaded manifests since at the time of writing this document we ran into this kubeflow bug that would not allow downloading the manifests during a build process.
    sed -i 's#uri: .*#uri: '$PWD'#' ./kfdef/kfctl_openshift.yaml
    kfctl build --file=kfdef/kfctl_openshift.yaml
    kfctl apply --file=./kfdef/kfctl_openshift.yaml
  3. Verify installation
    oc get pods
  4. Launch the Kubeflow portal
    oc get routes -n istio-system istio-ingressgateway -o jsonpath='http://{.spec.host}/'
    http://<istio ingress route>/

Delete A Kubeflow installation

To delete a Kubeflow installation please follow these steps:
kfctl delete --file=./kfdef/<kfctl file name>.yaml
rm -rf kfdef/kustomize/
oc delete mutatingwebhookconfigurations admission-webhook-mutating-webhook-configuration
oc delete mutatingwebhookconfigurations inferenceservice.serving.kubeflow.org
oc delete mutatingwebhookconfigurations katib-mutating-webhook-config
oc delete mutatingwebhookconfigurations mutating-webhook-configurations
