Problems solved by technology

[0003] In the prior art, when using Docker to publish applications, each machine to be released (for example, the host that needs to deploy the application) needs to download the Docker image from the Docker warehouse that saves the Docker image, and for long-distance cross-regional, cross-international, etc. For Docker image download scenarios or large-scale image distribution, the download efficiency of Docker images is relatively low

Abstract

The invention provides a downloading method and a node of a Docker mirror, a preheating method and a node of the Docker mirror. The downloading method is applied to a P2P client in an end-to-end P2P distribution system. The method comprises the following steps: a first P2P client sends a download request of a layer file mirrored by a Docker to a management and control node, so that the managementand control node determines a list of available super nodes according to the position of the first P2P client and the load of each super node; the first P2P client requests the optimal super node in the super node list to download the layer file so that the optimal super node generates fragmentation information of each fragment of the layer file, and the first P2P client downloads each fragment ofthe layer file locally from the optimal super node and / or other P2P clients according to the fragmentation information. As the embodiment of the present application is adopted, the download efficiency and stability of the Docker image can be improved.

Description

technical field [0001] The application relates to the technical field of Docker images, in particular to a method for downloading Docker images and related nodes, and a method for preheating Docker images and related nodes, as well as a P2P distribution system. Background technique [0002] Docker is an open source application container engine that allows application developers to package applications and dependent packages into a portable container, and then publish the portable container to any machine, that is, publish the application. At the same time, Docker can also implement virtualization, and the containers are completely isolated from each other using the sandbox mechanism. The Docker image can be composed of multiple read-only, mirror layer layer files to form a unified perspective, and each mirror layer contains several files and metadata. [0003] In the prior art, when using Docker to publish applications, each machine to be released (for example, the host tha...
