Mirror image caching method for edge computing virtual machine

The invention discloses an edge computing virtual machine mirror image caching method, which comprises the following steps of: exporting a self-defined mirror image of a virtual machine according to a user requirement, and generating a cache file at the same time; the cache file is accessed on the basis of nginx, and a user-defined mirror image of the virtual machine is uploaded to an image-proxy mirror image service agent program; the method comprises the following steps of: uploading a mirror image file to a cloud end for backup in a data stream form through an image-proxy mirror image service agent program, generating an nginx cache file in the process of uploading the mirror image file to the cloud end, and writing the cache file while uploading the mirror image through an io.tree pipeline mode, so as to carry out cloud mirror image backup; and downloading the mirror image based on nginx, and creating a new virtual machine in an original cluster to complete virtual machine deployment ...
