= Importing manifest lists in image streams on your multi-architecture compute machines

[role="_abstract"]
On an {product-title} {product-version} cluster with multi-architecture compute machines, the image streams in the cluster do not import manifest lists automatically. You must manually change the default `importMode` option to the `PreserveOriginal` option to import the manifest list.

.Prerequisites

* You installed the {oc-first}.

.Procedure

* Enter a command similar to the following example command to patch the `ImageStream` cli-artifacts so that the `cli-artifacts:latest` image stream tag is imported as a manifest list:
+
[source,terminal]
----
$ oc patch is/cli-artifacts -n openshift -p '{"spec":{"tags":[{"name":"latest","importPolicy":{"importMode":"PreserveOriginal"}}]}}'
----

.Verification

* You can check that the manifest lists imported properly by inspecting the image stream tag. The following command lists the individual architecture manifests for a particular tag.
+
[source,terminal]
----
$ oc get istag cli-artifacts:latest -n openshift -oyaml
----
+
If the `dockerImageManifests` object is present, the manifest list imported successfully.
+
.Example output of the `dockerImageManifests` object
