Container mirror image distribution system, container mirror image pushing method, container mirror image pulling method and container mirror image deleting method

Abstract

The invention provides a container mirror image distribution system, a container mirror image pushing method, a container mirror image pulling method and a container mirror image deleting method based on a P2P technology. The container mirror image distribution system comprises a container node cluster with a plurality of working nodes and a mirror image warehouse node, wherein the working nodes are used for receiving and forwarding a mirror image event request of a client in real time, and executing the mirror image event request according to a mirror image request event response; and the mirror image warehouse node is used for running a mirror image warehouse program and a P2P centralized retrieval server, responding to the mirror image event request of any working node, cooperating with the corresponding working node to complete the mirror image event request, and maintaining mirror image changes of the mirror image warehouse node through the P2P centralized retrieval server. According to the container mirror image distribution system, the container mirror image pushing method, the container mirror image pulling method and the the container mirror image deleting method, in mirror image distribution application, the problem that a mirror image warehouse in a large-scale container cluster limits the container starting speed is effectively solved, meanwhile, the number of seed files in the cluster is reduced, mirror image distribution stability is improved, and unnecessary network bandwidth loss is reduced.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to an intelligent container image distribution system, method, computer equipment and storage medium based on P2P technology. Background technique [0002] The emergence of virtualization technology has promoted the birth and development of the field of cloud computing, and human society has become more and more information-based and intelligent. The emergence of lightweight virtualization technology based on resource isolation and control technology, such as Docker, has injected more powerful impetus into the development of cloud computing. In the current Docker image distribution system, the worker nodes that start the container need to store the container image before starting, and the container image is usually pulled from the only Docker image warehouse in the cluster. The basic unit of image pulling is the image level, that is, the file change set generated by...
