Problems solved by technology

[0005] In the docker system, the number of images can be very large. Therefore, when multiple hosts download images, they must download not only the image data of the image, but also the metadata of the image, which will increase the overhead of the entire docker system, and different

Abstract

The embodiment of the invention provides an image management method, device and system, relates to the field of the computer technology, can reduce the transmission frequency of image data and improves the use ratio of a storage space so as to lower the expenditure of a docker system. The system comprises a warehouse server and N nodes connected with the warehouse server, wherein the store modules of the N nodes form a distributed storage system, and the image data of the images in the N nodes is shared in the distributed storage system; the first node is used for generating a first image, and the first image comprises first metadata and first image data; the first image data is stored in the distributed storage system; an upload request is sent to the warehouse server, wherein the upload request carries the first metadata, and the first node is any one node in the N nodes; and the warehouse server is used for receiving the upload request sent from the first node and storing the first metadata in the upload request.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a mirror image management method, device and system. Background technique [0002] Docker is an application hosting framework (application hosting framework), which can deploy and manage applications through containers similar to virtual machines. [0003] In the current docker system, each host is connected to the remote docker registry (ie, warehouse server), and each host needs to download (pull) the required image (ie, image) from the warehouse server when performing docker instantiation operations , and save it in the local warehouse; correspondingly, if the host modifies the mirror image and obtains a new mirror image, it needs to upload (push) the new mirror image to the warehouse server. [0004] Specifically, images can be hierarchically stored in the warehouse server in the form of a tree, and the branches from each node to the root node can form a image, suc...
