8.2.3. Adding a custom golden image in a heterogeneous cluster

Procedure

1. Open the HyperConverged CR in your default editor by running the following command:

   $ oc edit hyperconverged kubevirt-hyperconverged -n openshift-cnv

2. Edit the HyperConverged CR, to add the custom golden image. You must add the appropriate values for ssp.kubevirt.io/dict.architectures annotation in the dataImportCronTemplates section. For example:

   apiVersion: hco.kubevirt.io/v1beta1
   kind: HyperConverged
   metadata:
     name: kubevirt-hyperconverged
   spec:
     dataImportCronTemplates:
     - metadata:
         name: custom-image1
         annotations:
           ssp.kubevirt.io/dict.architectures: "<architecture_list>"
       spec:
         schedule: "0 */12 * * *"
         template:
           spec:
             source:
               registry:
                 url: docker://myprivateregistry/custom1
         managedDataSource: custom1
         retentionPolicy: "All"
   #...

   where:

   <architecture_list>

   Specifies a comma-separated list of supported architectures for this image. For example, if the image supports amd64 and arm64 architectures, the value would be "amd64,arm64".

   注記

   An image may support more architectures than you want to use in your cluster. You do not have to list all of the architectures an image supports, only those for which you want to create a boot source.

3. Save and exit the editor to update the HyperConverged CR.
