A host performance expansion method and device for a swarm cluster

Abstract

The invention discloses a host machine performance expansion method of a swarm cluster, comprising: acquiring performance parameters of a target container, and the target container is deployed in a target node in a swarm cluster; judging whether the performance parameters of the target container are greater than a preset threshold; , then obtain the installation package, dependency package and extension components of the target container, call the preset installation script to install the installation package, dependency package and extension components to the preset destination node, and connect the destination node to the swarm cluster. The method automatically determines the container to be expanded based on a preset threshold, invokes a preset installation script to install the corresponding expansion components of the container to be expanded on the destination node, and connects the destination node to the swarm cluster, thereby automatically completing the performance expansion of the swarm cluster. Thus, the expansion efficiency and accuracy are improved. The host performance expansion device, device and readable storage medium of the swarm cluster disclosed by the present invention also have the above technical effects.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, to a method, device, device and readable storage medium for extending the performance of a swarm cluster host computer. Background technique [0002] Swarm is a set of tools for managing Docker clusters, so that when exposed to users, the Docker cluster is equivalent to a virtual whole. That is: users cannot perceive the number and distribution of nodes in the swarm cluster. A swarm cluster can be regarded as a huge host machine, which includes multiple physical nodes, and each physical node deploys multiple container services. If the performance of the host machine of the current swarm cluster is poor and the user experience is not good, the performance of the host machine needs to be expanded. Wherein, the host machine of the swarm cluster refers to the swarm cluster, and then the performance expansion of the host machine of the swarm cluster is the performanc...

Problems solved by technology

[0004] However, since the existing expansion method requires manual operation by technicians, when there are many containers to be expanded or many components to be expanded, the workload of the manual implementation method will be very large, and the expansion efficiency will inevitably be affected; and, manual operation It is inevitable that there will be errors, and the error rate cannot be controlled, which will reduce the user experience
