==== Pinning images to nodes In clusters with slow, unreliable connections to an image registry you can use a `PinnedImageSet` object to pull the images in advance, before they are actually needed, then associate those images with a machine config pool. This ensures that the images are available when needed. The `must-gather` for the Machine Config Operator now includes all `PinnedImageSet` objects in the cluster. For more information, see xref:../machine_configuration/machine-config-pin-preload-images-about.adoc#machine-config-pin-preload-images_machine-config-operator[Pinning images to nodes].
