Spegel itself does not manage state as a normal registry would. Maybe ephemeral would be a better word to describe it. A normal registry would require some stateful storage solution along with a database to store image that clients push to it. Spegel exploits the fact that images used by containers will be stored on disk by Containerd for its benefit. Any image currently being used by a pod in a cluster will be available for all other nodes in the cluster to pull.
