Embodiment Construction

[0060] In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0061] refer to figure 1 , showing a flowchart of the steps of an image upgrade method provided by an embodiment of the present invention, which may specifically include the following steps:

[0062] Step 101: Acquire upgrade image layer data for a first base image; wherein the first base image includes libraries and programs that applications depend on, and the upgrade image layer data includes upgrade data for the first base image.

[0063] In this embodiment of the present invention, the base image is an image that one or more applications depend on, including libraries and programs that the applications depend on. The base image to be upgraded this time is recorded as the first base image, and the base image after this upgr...

Abstract

The embodiment of the invention provides a mirror image upgrading method and device, electronic equipment and a storage medium. The method comprises the steps that upgrading mirror image layer data aiming at a first basic mirror image are obtained, the first basic mirror image comprises a library and a program on which an application depends, the upgrading mirror image layer data comprise upgrading data aiming at the first basic mirror image, a second basic mirror image is obtained through combination according to the first basic mirror image and the upgrading mirror image layer data, and the second basic mirror image is updated according to the upgrading data. According to the second basic mirror image and the application mirror image layer data, the first application mirror image is obtained through combination, the application mirror image layer data comprises the ontology data of the application, an upgrading mirror image layer is overlaid on the basic mirror image of the application to form a new basic mirror image, and therefore the problem of re-downloading or re-making the whole file system is avoided; according to the method, the existing local mirror image is utilized to the greatest extent, and the new basic mirror image can be reused for other applications, so that the problem that each application needs to be upgraded separately is avoided, the storage space is saved, and the complexity of mirror image management is reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to an image upgrade method, an image upgrade apparatus, an electronic device and a readable storage medium. Background technique [0002] In a computer, a file system is a system for naming files and placing them for logical storage and retrieval. For example, a Docker (Application Container Engine) image (Image) is equivalent to a file system. [0003] The image can be created by the server in advance, and the client needs to download the entire image. If the software package in the image is upgraded, the entire image needs to be re-created on the server and re-delivered to the client. At this time, the data transferred between the local terminal and the remote server is still the entire file system, although many files in this file system are the same as the previous file system. [0004] The upgrade of the image has the problem that the entire file system needs ...
