Dynamic load balancing method and system for container cluster

Abstract

The embodiment of the invention discloses a dynamic load balancing method and system for a container cluster. The method comprises the following steps: initiating connection to a load balancer by a container and registering; upon receiving a registration request from a newly added container, creating queue nodes corresponding to the service provided by the newly added container by the load balancer, mounting the created queue nodes to a queue corresponding to an identification mark of the service provided by the newly added container; when receiving a service request from a service request source, determining the queue corresponding to the service identification mark carried in the service request; determining the container corresponding to the node with minimum load in the determined queue as the target container; forwarding the service request to the target container. In the process, the balance configuration file is not required to be configured in advance, the load balancer is not required to restart, but the load balance is realized automatically, so that the dynamic load balancing method solves the problem that the existing load balancing method is difficult to adapt to the container cluster which is used for providing back-end service and changeable dynamically in a cloud computing system.

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...
