Abstract

The invention provides a Kubernetes scheduling method, device and storage medium, which filters out Node nodes that do not meet the requirements according to a pre-selection algorithm; sets queues for each Node node according to resource types; assigns priorities to Pods to be scheduled; analyzes Pods to be scheduled Status; when the cluster resources are satisfied, the Pod calculates the similarity according to the first rule, and searches for the first Node node for scheduling; when the cluster resources are not satisfied, it enters preemptive scheduling, sets the first rule to calculate the similarity and the second rule priority preemption rule, and searches for The Node node performs preemptive scheduling; set the maximum number of cycles for Pods that cannot be scheduled, and when the maximum is reached, priority is given to scheduling. The invention solves the problem that the priority is set regardless of the actual situation of the cluster resources, the resources cannot be reasonably arranged during the preemption process, and the scheduling cannot be completed all the time. The invention improves the integrity of task operation and the load balance of the entire cluster, reduces the generation of resource fragments, improves the timeliness of scheduling, and enhances the efficiency of resource scheduling in the cluster management system.

Description

technical field [0001] The invention relates to the technical field of container arrangement, in particular to a method for realizing a Kubernetes scheduling strategy. Background technique [0002] Kubernetes is an open source system, mainly used for the management of integrated applications across hosts in the cluster. A core feature of Kubernetes is that it dynamically manages containers to ensure that the state of the cluster meets user needs. Pod is the smallest unit for scheduling and management in the cluster. All containers run in the Pod, and each Pod can run one or more containers. Each cluster consists of control node Master and Node nodes ( figure 1 ). The core of the Scheduler (scheduler) is how to select the appropriate Node node from the cluster to assign to the Pod to be scheduled ( figure 2 ). [0003] Most of the current kubernetes resource scheduling algorithms score and prioritize Node nodes, such as the built-in LeastRequested and Priority algorithm...
