Abstract

The invention discloses a cluster node load balancing method and device, and a computer storage medium, which are used for solving the technical problems of poor real-time performance of resource optimization scheduling in a cluster, unbalanced resource utilization of each node and the like. According to the method, the periodically running load balancing task is configured in the Kubernetes cluster; the method comprises the following steps: preliminarily determining a Pod to be expelled on a node based on a pre-configured load balancing strategy in three aspects of comprehensively consideringa single copy, node balancing and condition re-adaptation; screening out to-be-expelled Pod meeting a scheduling condition according to a Pod expelling rule; and finally, calling a Pod scheduler to schedule the to-be-expelled Pod determined to be expelled to an optimal node. According to the method, the resource utilization of each node of the cluster is more balanced, the utilization rate of cluster resources is improved, the optimal operation environment of the Pod is continuously ensured, the occurrence frequency of resource recovery operations such as Pod expelling is reduced, and the stability of the cluster is maintained.

Description

Technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a cluster node load balancing method, device and computer storage medium. Background technique [0002] Kubernetes is an open source platform for automated container operations. It can automate the deployment and replication of containers, expand or shrink the scale of containers, organize containers into groups and provide load balancing between containers. It is easy to upgrade the version of application containers and provide containers. Rich functions such as flexibility. [0003] Kubernetes is usually deployed in the form of a cluster. The cluster is composed of a set of nodes, which can be physical servers or virtual machines. The architecture diagram of the Kubernetes cluster is as follows: [0004] The Node node in the Kubernetes cluster is an abstraction of cluster resources. The Pod in the Kubernetes cluster is the encapsulation of the container and the entity...
