When using oc mirror with an imageset-config.yaml that contains only a couple of operators, the resulting index image referenced by the catalogsource is showing all the packages in the upstream catalog.

Expected result is that in OperatorHub on the disconnected cluster only the two packages referenced in the imageset-config.yaml would display

$ oc mirror version --output=yaml
clientVersion:
  buildDate: "2024-06-05T22:52:38Z"
  compiler: gc
  gitCommit: e91f573c771182f7fd4a2d3513ed49562dee6b38
  gitTreeState: clean
  gitVersion: 4.15.0-202406052127.p0.ge91f573.assembly.stream.el9-e91f573

1.create the following imageset-config.yaml

 
kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2
storageConfig:
  registry:
    imageURL: fminafra-mirror-registry.c.cee-gcp-emea.internal:8443/mirror/oc-mirror-metadata
    skipTLS: false
mirror:
  platform:
    channels:
    - name: stable-4.15
      type: ocp
      minVersion: 4.15.15
      maxVersion: 4.15.16
    graph: true
  operators:
  - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.15
    packages:
    - name: cluster-logging
      channels:
      - name: stable-5.9
        minVersion: '5.9.2'
        maxVersion: '5.9.2'
    - name: cincinnati-operator
      channels:
      - name: v1
        minVersion: '5.0.2'
        maxVersion: '5.0.2'


2. mirror the release images and operators to a local registry


3. apply the resulting catalogsource to the cluster:

apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: fminafra-disconnected-operator-catalog
  namespace: openshift-marketplace
spec:
  image: fminafra-mirror-registry.c.cee-gcp-emea.internal:8443/ocp4/openshift4/redhat/redhat-operator-index:v4.15
  sourceType: grpc
  displayName: My disconnected Operator Catalog
  publisher: Francesco Minafra
  updateStrategy:
    registryPoll:
      interval: 3m
 

all the 114 operators are showing in operatorhub on the disconnected cluster and in the output of command:

$ oc get packagemanifest -n openshift-marketplace

only two operators should appear in operatorhub and in the output of the  packagemanifest command
