In OCP 4.14 the catalog pods in openshift-marketplace where defined as:

$ oc get pods -n openshift-marketplace redhat-operators-4bnz4 -o yaml
apiVersion: v1
kind: Pod
metadata:
...
  labels:
    olm.catalogSource: redhat-operators
    olm.pod-spec-hash: 658b699dc
  name: redhat-operators-4bnz4
  namespace: openshift-marketplace
...
spec:
  containers:
  - image: registry.redhat.io/redhat/redhat-operator-index:v4.14
    imagePullPolicy: Always



Now on OCP 4.15 they are defined as:
apiVersion: v1
kind: Pod
metadata:
...
  name: redhat-operators-44wxs
  namespace: openshift-marketplace
  ownerReferences:
  - apiVersion: operators.coreos.com/v1alpha1
    blockOwnerDeletion: false
    controller: true
    kind: CatalogSource
    name: redhat-operators
    uid: 3b41ac7b-7ad1-4d58-a62f-4a9e667ae356
  resourceVersion: "877589"
  uid: 65ad927c-3764-4412-8d34-82fd856a4cbc
spec:
  containers:
  - args:
    - serve
    - /extracted-catalog/catalog
    - --cache-dir=/extracted-catalog/cache
    command:
    - /bin/opm
...
    image: quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:7259b65d8ae04c89cf8c4211e4d9ddc054bb8aebc7f26fac6699b314dc40dbe3
    imagePullPolicy: Always
...
  initContainers:
...
  - args:
    - --catalog.from=/configs
    - --catalog.to=/extracted-catalog/catalog
    - --cache.from=/tmp/cache
    - --cache.to=/extracted-catalog/cache
    command:
    - /utilities/copy-content
    image: registry.redhat.io/redhat/redhat-operator-index:v4.15
    imagePullPolicy: IfNotPresent
...



And due to `imagePullPolicy: IfNotPresent` on the initContainer used to extract the index image (referenced by tag) content, they are never really updated. 


    

    OCP 4.15.0    

    100%    

    1. wait for the next version of a released operator on OCP 4.15
    2.
    3.
    

    Operator catalogs are never really refreshed due to  imagePullPolicy: IfNotPresent for the index image

    Operator catalogs are periodically (every 10 minutes by default) refreshed
