Problems solved by technology

The Kubernetes platform can meet the needs of most distributed system deployment and management, but in different application business environments, there may be some special requirements for the platform, which can be abstracted as extended resources of Kubernetes, and CRD (CustomResource Definition) of Kubernetes Provides a lightweight mechanism for such requirements to ensure the rapid registration and use of new resources. The scheduler of K8s itself has some defects: (1) The default scheduler is based on Pod as the granularity, which is very difficult for machine learning tasks. Disadvantage; (2) The default scheduler cannot provide the function of queue scheduling

Abstract

The invention provides a method for configuring the queues of a Kubernetes scheduler. The method comprises the following steps of polling all queues to query the task information in each queue in a scheduling period, and calculating an allocated resource value of each queue; calculating the proportion of the resources required by each queue in the resources required by all the queues, and obtaining the residual resource value in a cluster which can be used by the queues based on the proportion; and calculating the ratio of the allocated resource value of the queue to the remaining resource value in the cluster which can be used by the queue, and setting the priority of the queue according to the ratio. According to the method, the cluster resource utilization rate and the performance for deeply learning and training the task are improved, and a system scheduling strategy is optimized.

Description

technical field [0001] The present invention relates to the computer field, and more specifically, to a configuration method and device for a queue of a Kubernetes scheduler. Background technique [0002] Kubernetes is a container orchestration engine open sourced by Google, which supports automated deployment, large-scale scalability, and application container management. When an application is deployed in a production environment, multiple instances of the application are usually deployed to load balance application requests. In Kubernetes, we can create multiple containers, run an application instance in each container, and then use the built-in load balancing strategy to realize the management, discovery, and access of this group of application instances, and these details do not require operation and maintenance. personnel to perform complex manual configuration and processing. The Kubernetes platform can meet the needs of most distributed system deployment and manage...
