You can use a mirror registry for disconnected installations and to ensure that your clusters only use container images that satisfy your organization's controls on external content.

Before you install a cluster on infrastructure that you provision in a disconnected environment, you must mirror the required container images into that environment. To mirror container images, you must have a registry for mirroring.

You can use one of the following procedures to mirror your {product-title} image repository to your mirror registry:

* "Mirroring images for a disconnected installation by using the oc-mirror plugin v2"
* "Mirroring images for a disconnected installation"
