Open Data Hub Operator : Dev Preview

ODH Operator is introducing new CRD called DataScienceCluster. The new feature set will be released in phases and will be made available before release in the form of a custom Operator catalog

Deploying Custom Catalog

New Installation

  1. ODH Operator team will provide new catalogsource image with tag corresponding to latest pre-release in ODH releases.

Alternatively, you can directly get the preview version

export RELEASE_TAG=$( curl https://api.github.com/repos/opendatahub-io/opendatahub-operator/releases | jq -r 'map(select(.prerelease)) | first | .tag_name')
  1. Deploy CatalogSource
cat <<EOF | oc create -f -
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: opendatahub-dev-catalog
  namespace: openshift-marketplace
spec:
  sourceType: grpc
  image: quay.io/opendatahub/opendatahub-operator-catalog:$RELEASE_TAG
  displayName: Open Data Hub Operator (Preview)
  publisher: ODH
EOF

cat <<EOF | oc create -f -

  namespace: openshift-operators

Upgrade to new Dev Preview Version

  1. Apply updated version of catalog
export NEW_RELEASE_TAG=$( curl https://api.github.com/repos/opendatahub-io/opendatahub-operator/releases | jq -r 'map(select(.prerelease)) | first | .tag_name')
cat <<EOF | oc apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: opendatahub-dev-catalog
  namespace: openshift-marketplace

Usage

  1. When Operator is installed it creates a namespace called opendatahub.
  2. Users need to create required DataScienceCluster resource by going to the Installed Operators tab in the OpenShift Cluster.
  3. Users should explicitly set components with enabled: true in order for components to be installed.
cat <<EOF | oc apply -f -
apiVersion: datasciencecluster.opendatahub.io/v1alpha1
kind: DataScienceCluster
metadata:
  name: example
spec:
  components:
    codeflare:
      enabled: true
    dashboard:
      enabled: true
    datasciencepipelines:
      enabled: true
    kserve:
      enabled: true
    modelmeshserving:
      enabled: true
    ray:
      enabled: true
    workbenches:
