Abstract

The invention discloses a method and a system for assembling mirror image files, wherein the method comprises the following steps: acquiring all assembled files required by current mirror image files according to the assembling requests of the current mirror image files; generating all assembled files to be an orderly assembled file sequence according to preset software dependency relationship and software release dependency relationship; determining the file attribute of each assembled file in the orderly assembled file sequence according to the file layout of the assembled files recorded in the resource library of the assembled files; and assembling each assembled file according to an assembling path in sequence according to the determined file attribute to obtain the current mirror image files. According to the method and the system for assembling mirror image files, the storage of the software dependency relationship and the software release dependency relationship is used for replacing the storage of different mirror image files, and the space required for storing the software dependency relationship and the software release dependency relationship is smaller than the size of a mirror image file; and therefore, a large amount of storage space is saved.

Description

technical field [0001] The invention relates to computer technology, in particular to a method and system for assembling image files. Background technique [0002] In a virtualized data center environment, a virtual machine image file (mirror file) is a form of storage on a storage device in which software runs in a virtualized environment to support the server's operating environment. The image file contains the operating system, software and other data that depend on the operation period. The image file is large and takes a long time to build. In order to avoid frequent duplication and construction of image files, those skilled in the art usually store virtual machine image files installed with different software in the form of building a virtual machine image asset library. The user can find the required image file by querying the asset library and store the image file on a designated physical server for operation. [0003] Since the size of the image file is usually at...
