Container migration method and related device

Abstract

The invention discloses a container migration method, which comprises the steps of performing node load calculation on a plurality of nodes to obtain a node load corresponding to each node; performingcontainer load calculation on each container in the node of which the node load is greater than a preset upper limit threshold to obtain a container load corresponding to each container; performing complementation degree calculation on the to-be-migrated container with the minimum container load and a plurality of target nodes to obtain a complementation degree corresponding to each target node;and migrating the to-be-migrated container to a target node with the maximum complementation degree. According to the container migration method and device, high-efficiency container migration operation is achieved, the to-be-migrated container with the minimum container load is migrated, the load balancing efficiency is improved, the influence on node application is avoided, and the migration effect is kept. The invention further discloses a container migration device, a server and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a container migration method, a container migration device, a server, and a computer-readable storage medium. Background technique [0002] With the continuous development of information technology, more and more network applications are deployed in operating system-level virtualization containers based on Linux containers. Among them, the Docker container is one of the operating system-level virtualization containers. Docker is an open source application container engine that allows developers to package applications and dependencies into a portable container, and then publish it to any popular Linux machine or Windows machine. It can also implement virtualization. The container is completely built using sand Box mechanism, there will be no interface between each other. [0003] In the prior art, generally multiple containers are set up on hardware nodes for de...

Problems solved by technology

However, when different containers are normally applied to the node, the container with a large load tends to affect the node load

For this reason, the containers in the nodes are generally migrated accordingly, but the migration operations in the prior art are inefficient, the migration effect is not good, and the performance of the nodes to execute the containers cannot be improved.
