Mirror image file distribution method and system, computer readable storage medium and electronic equipment

Abstract

The disclosure relates to a mirror image file distribution method and system, a computer readable storage medium and electronic equipment. The mirror image file distribution method includes the following steps: acquiring a mirror image file to be distributed to a node; creating a corresponding seed file according to mirror image block files and a configuration file included in the mirror image file, wherein each mirror image block file includes identification information, and the identification information of all the mirror image block files constitutes basic identification information; savingand distributing the seed file and the basic identification information; judging whether the mirror image block files exist locally according to the identification information of all the mirror imageblock files included in the basic identification information, and acquiring a seed file corresponding to the mirror image block files that do not exist locally; and parsing the seed file to obtain anindex server, and performing communication with the index server and other nodes to download the mirror image block files corresponding to the seed file. According to the scheme of the disclosure, the host I/O and bandwidth pressure on warehouse server services and storage mirror images can be alleviated, and the speed and performance of mirror image distribution can also be improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a method and system for distributing image files, a computer-readable storage medium, and electronic equipment. Background technique [0002] Docker is an open source application container engine, which can package applications and their dependent environments into a portable container to achieve access control and resource isolation. When a Docker containerized application is running, a Docker container needs to be created and started. As a dynamic resource, a Docker container is created from a Docker image. Due to the diversity, portability, and sharing of Docker images, it is determined that Docker images need a dedicated central point for storage, so Docker Registry (warehouse server) came into being, which is mainly responsible for image storage and management operations. Such as figure 1 As shown, when a containerized application needs to be run on the node...

AI Technical Summary

Problems solved by technology

However, in the actual production environment, there are a large number of host nodes (100+) that need to download images from the warehouse server at the same time. In terms of speed and performance, the warehouse server service and the host I / O (input / output) of the storage image will become mirror images. The bottleneck of distribution, so the existing technology cannot solve the problem of image distribution in large-scale clusters
