Abstract

The invention provides a container cross-host online migration method, a storage medium and terminal equipment. The method comprises the following steps of carrying out resource monitoring on each physical node of the cloud platform; setting a migration threshold as a judgment condition for triggering container migration; selecting a container with the minimum migration cost as a container to be migrated; determining a physical node of which the comprehensive load value is smaller than a set value, calculating an average value of the comprehensive load values of the physical nodes; selecting aphysical node with a comprehensive load value closest to the average value as a target node; and executing migration until the comprehensive load value of a certain node is smaller than a migration threshold value, so that load balance of each physical node in the cluster can be maintained, services in the container are not interrupted while the container migrates, and thus elastic scheduling ofDocker cloud platform resources is realized.

Description

technical field [0001] The present disclosure relates to a container cross-host online migration method, a storage medium and a terminal device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Cloud computing, as an emerging computing model, has received more and more attention and applications in recent years. With the expansion of cloud service scale and the continuous expansion of data centers, in order to effectively achieve load balancing under large-scale cloud platforms, The reasonable dynamic allocation of computing resources and the application of online migration technology have gradually become the consensus and research hotspot in the industry. In the traditional mode, the core content of cloud computing is virtualization technology, which improves the utilization rate of computing resources through virtual machines, and the ...
