Dynamic load balancing method and system for container cluster

Abstract

The embodiment of the present invention discloses a dynamic load balancing method and system for a container cluster. The container actively initiates a connection to and registers with a load balancer, and when the load balancer receives a registration request for a newly added container, it creates a new Add the queue node corresponding to the service provided by the container, mount the newly created queue node to the queue corresponding to the identification of the service provided by the newly added container, and when receiving the service request sent by the service request source, determine the corresponding service request The queue corresponding to the service identifier carried in the queue is determined; the container corresponding to the node with the smallest load in the determined queue is determined as the target container; the service request is forwarded to the target container. This process does not need to pre-configure the balancing configuration file or restart the load balancer, automatically achieves load balancing, and overcomes the problem that the current load balancing method is difficult to adapt to the dynamically changing container clusters used to provide back-end services in cloud computing systems.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, and more specifically, to a dynamic load balancing method and system for container clusters. Background technique [0002] The application of container technology in the field of cloud computing is becoming more and more common. Cloud computing systems usually form multiple containers into clusters to provide services for users, and provide users with a single access portal through a load balancer, so that users do not need to care about or notice it. The service is provided by multiple containers in the cluster. In a container cluster, each container hosts a service, and the services hosted by different containers may be the same or different. [0003] Container clusters often need to change according to the service load: when the load increases, more containers are created to balance the load of each container, so that each container can provide services to users smoothly; when...
