As part of the spike https://issues.redhat.com/browse/OSPRH-15230 it was decided that OpenStack Lightspeed will reuse the already existing "openstack" operator for OpenShift.

Now we need to integrate the new container containing the OpenStack/RHOSO RAG image into the existing "openstack" operator so it can be deployed and configured correctly.

Configuration: 

The multiple RAG feature for OpenShift Lightspeed will be released on the version 0.3.4 according to it's developers, until then, Haoyu Sun has provided a catalog that can be used for our tests:

• Create a file called ols-catalog.yaml with the following contents:

apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: lightspeed-operator-catalog
  namespace: openshift-marketplace
spec:
  displayName: OpenShift Lightspeed Operator
  sourceType: grpc
  image: docker.io/raptorsun/lightspeed-catalog:0.33.1
  updateStrategy:
    registryPoll:
      interval: 10m 

• Apply this file using oc apply -f:

oc apply -f ols-catalog.yaml 

Once that's done, you can install the new Lightspeed operator via OperatorsHub.

• Apart from the normal configuration for Lightspeed (e.g creating the secret file, adding the extra certificate if needed etc...) below is a snippet of how to plug multiple RAGs in the OLSConfig ConfigMap:

apiVersion: ols.openshift.io/v1alpha1
kind: OLSConfig
metadata:
  name: cluster
...
  ols:
    introspectionEnabled: true
    rag:
      - image: quay.io/...:latest
        indexPath: /rag/vector_db
        indexID: vector_db_index0
      - image: quay.io/...:latest
        indexPath: /rag/vector_db
        indexID: vector_db_index1

Note that we still have the problem with the "question validator prompt" that will be addressed by https://issues.redhat.com/browse/OSPRH-16233
