= Updating the disconnected cluster
|
|
|
|
Update the disconnected cluster to the {product-title} version that you downloaded the release images for.
|
|
|
|
//TODO: Add xrefs in the following note when functionality is enabled.
|
|
|
|
[NOTE]
|
|
====
|
|
If you have a local OpenShift Update Service, you can update by using the connected web console or CLI instructions instead of this procedure.
|
|
====
|
|
|
|
.Prerequisites
|
|
|
|
* You mirrored the images for the new release to your registry.
|
|
* You applied the release image signature ConfigMap for the new release to your cluster.
|
|
+
|
|
[NOTE]
|
|
====
|
|
The release image signature config map allows the Cluster Version Operator (CVO) to ensure the integrity of release images by verifying that the actual image signatures match the expected signatures.
|
|
====
|
|
* You obtained the sha256 digest for your targeted release image.
|
|
* You installed the OpenShift CLI (`oc`).
|
|
* You paused all `MachineHealthCheck` resources.
|
|
|
|
.Procedure
|
|
|
|
* Update the cluster:

[source,terminal]

|
----
|
|
$ oc adm upgrade --allow-explicit-upgrade --to-image ${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}@<digest> <1>
|
|
----
|
|
<1> The `<digest>` value is the sha256 digest for the targeted release image, for example, `sha256:81154f5c03294534e1eaf0319bef7a601134f891689ccede5d705ef659aa8c92`
|
|
+
|
|
If you use an `ImageContentSourcePolicy` for the mirror registry, you can use the canonical registry name instead of `LOCAL_REGISTRY`.
|
|
+
|
|
[NOTE]
|
|
====
|
|
You can only configure global pull secrets for clusters that have an `ImageContentSourcePolicy` object. You cannot add a pull secret to a project.
