      Description of problem:

      As a OCP Integrator, I would like to use kernel-module-management operator in an air gap environment.

      Version-Release number of selected component (if applicable):

      KMMv2.0.0

      How reproducible:

          100%

      Steps to Reproduce:

       
      In a Air Gap environment, in order to deploy OCP its required to mirror all the dependencies to a local registry:

      apiVersion: mirror.openshift.io/v1alpha2
kind: ImageSetConfiguration
mirror:
  platform:
   channels:
   - name: stable-4.14
     minVersion: 4.14.9
     maxVersion: 4.14.9
   graph: true
  operators: # Operators we want to mirror
  - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.14
    packages:
    - name: kernel-module-management
      channels:
      - name: stable
    - name: kernel-module-management-hub
      channels:
      - name: stable

      Once the mirroring its completed `mapping.txt` content:

      registry.redhat.io/kmm/kernel-module-management-operator-bundle@sha256:69b16d605af30119072ad3ab8594693ac6d7cbeb040ef26046286e71ceb6b92e=rock5b.offline.oxtechnix.lan:5000/kmm-test-414/kmm/kernel-module-management-operator-bundle:6c5c78b9registry.redhat.io/kmm/kernel-module-management-hub-rhel9-operator@sha256:e66b83a61a6a96ecdb6fecde1069883004adec627ebdeb683bdc57419190e824=rock5b.offline.oxtechnix.lan:5000/kmm-test-414/kmm/kernel-module-management-hub-rhel9-operator:729cce60registry.redhat.io/kmm/kernel-module-management-hub-operator-bundle@sha256:ef3a9010a9ffd3de442167635e76a292089b8be8f377a971bd152ad98ccb4155=rock5b.offline.oxtechnix.lan:5000/kmm-test-414/kmm/kernel-module-management-hub-operator-bundle:c6f9b2ddregistry.redhat.io/kmm/kernel-module-management-rhel9-operator@sha256:6dbd524edc1007846946044cd8b87dedc25bfe4cc4189cd2423a6b1c15f931dc=rock5b.offline.oxtechnix.lan:5000/kmm-test-414/kmm/kernel-module-management-rhel9-operator:c089bb05

      using the following CR:

      apiVersion: kmm.sigs.x-k8s.io/v1beta1
kind: Module
metadata:
  name: ran-nic-oot
  namespace: openshift-kmm
spec:

          - octeon_ep

        - regexp: '^.*x86_64$'
          containerImage: "rock5b.offline.oxtechnix.lan:5000/nic-drivers/loki/loki-v23.12-kmm_poc_v1-n0: 5.14.0-284.45.1.el9_2.x86_64"
  imageRepoSecret:
    name: pull-secret
  selector:
    node-role.kubernetes.io/worker: ""

      its creating a container on the worker nodes

      $ oc get pods -n openshift-kmm
NAME                                                                 READY   STATUS             RESTARTS       AGE
kmm-operator-controller-7bcc97dbbb-68sbx                             2/2     Running            8 (2d3h ago)   2d20h
kmm-worker-master0-ran-nic-oot   0/1     ImagePullBackOff   0              2d13h
kmm-worker-worker0-rdnet.net-ran-nic-oot   0/1     ImagePullBackOff   0              2d13h

      The resources created in `ImagePullBackOff` are trying to pull the following container base image:

      registry.redhat.io/kmm/kernel-module-management-worker-rhel9@sha256:999f83b0c65c96c8a66f144af931633e9ef489b6b5829c33b4bf3e46336a0360

      Which is not made available throught the operator mirror.
      Actual results:

      $ oc get pods -n openshift-kmm NAME                                                                 READY   STATUS             RESTARTS       AGE kmm-operator-controller-7bcc97dbbb-68sbx                             2/2     Running            8 (2d3h ago)   2d20h kmm-worker-master0-ran-nic-oot   0/1     ImagePullBackOff   0              2d13h kmm-worker-worker0-rdnet.net-ran-nic-oot   0/1     ImagePullBackOff   0              2d13h

      Expected results:

          I would expect that the registry.redhat.io/kmm/kernel-module-management-worker-rhel9@sha256:999f83b0c65c96c8a66f144af931633e9ef489b6b5829c33b4bf3e46336a0360 be included in the operator bundle and mirrored in an Air Gap environment this is made available.
