Cloud native virtual machine mirror image management system and method

The invention discloses a cloud native virtual machine mirror image management system and method, and the method comprises the following steps: creating a mirror image: creating a mirror image object, and appointing the object information and downloading address of the mirror image object; creating a corresponding cache data volume under a corresponding storage class for the mirror image object, the cache data volume being created in a system namespace; through the cache data volume, filling the mirror image object into a cache PVC (Poly Vinyl Chloride) by utilizing a CDI (Call Data Interface), and after the filling is completed, creating a VolumeSnapshot object for the cache data volume; the method comprises the following steps of: calling a storage CSI (Channel State Information) snapshot interface under the condition that a snapshot VolumeSnapshot object is monitored by a snapshot controller of k8s, creating a snapshot on a storage cluster, and generating a VolumeSnapshot Content object so as to associate
