specific Embodiment

[0066] The present invention also provides a specific embodiment, which is applied to a file backup management method of a high-performance distributed container image distribution system, referring to Figure 4 , the method includes:

[0067] There are two constants T, CL, and fLimit0 set when the system starts; T means to start backup management every time T; CL means the node cache size that can be used by each docker node; fLimit0 means the initial backup number of files;

[0068] Scan the service log in this cycle, for file f, if the file f is downloaded in this cycle, its backup quantity fLimit will be added; otherwise, its backup quantity fLimit will be decreased;

[0069] For each node in the system, calculate its weight. The weight calculation formula is weight=CL-actually used cache size. When the calculation result is less than 0, take 0;

[0070] For each image layered file in the system, if its actual backup number fNum is greater than fLimit, select fNum-fLimit ...

Abstract

The invention discloses a high-performance distributed container mirror image distribution system and method. The system comprises a main warehouse module, a scheduling module and a node processing module. The method comprises the steps that a main warehouse module forwards a mirror image pulling request; the scheduling module analyzes to obtain a to-be-pulled file list and sends data to the nodeprocessing module; the node processing module acquires the surprise hierarchical file and transmits the file through the IB network. According to the system and the method disclosed in the invention,the service pressure of the container mirror image server is reduced. The high-performance distributed container mirror image distribution system and method can be widely applied to the field of container cloud computing.

Description

technical field [0001] The invention relates to the field of container cloud computing, in particular to a high-performance distributed container image distribution system and method. Background technique [0002] As a lightweight, portable, and low-cost virtualization processing method, containers have become a way for many companies to reduce costs and improve efficiency. Starting a container requires container image files on the hard disk. In cloud-native scenarios, these image files need to be pulled from the container image warehouse. When a job needs to start the same container on multiple nodes, these nodes will upload to the image warehouse The image file is requested, but the export bandwidth of the mirror warehouse node is limited, so the average preparation time of the job on each node has a linear relationship with the deployment scale of the node. There have been some ways to optimize this problem in the industry, but the download of these method image layers i...
