image-registry Operator is not initially available for platforms that do
not provide default storage. After installation, you must configure your
registry to use storage so that the Registry Operator is made available.
Instructions are shown for configuring a PersistentVolume, which is required for production clusters. Where applicable, instructions are shown for configuring an empty directory as the storage location, which is available for only non-production clusters.
Additional instructions are provided for allowing the image registry to use block storage types by using the
Recreate rollout strategy during upgrades.
