Problems solved by technology

[0003] On a cluster using a local storage system, the Kubernetes native scheduling framework has obvious shortcomings: Pod events do not consider whether the node has sufficient storage resources when scheduling, resulting in unbalanced and fragmented allocation of node storage resources, and even Pod events due to insufficient storage resources. The event scheduling fails, or after the scheduling is successful, the storage volume cannot be created, which seriously affects the planning, management and scheduling of storage resources.

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0027] Among related technologies, Kubernetes is a set of open source software framework based on container technology and released under the Apache 2.0 license agreement. In the Kubernetes container orchestration system, Pod is the smallest logical unit of container operation, and the scheduler schedules it to the optimal node according to the pre-selected and optimized algorithm. The native scheduler framework (Scheduler Framework v2) opens the extension point of the scheduling cycle, allowing built-in and exter...

Abstract

The embodiment of the invention provides a storage resource scheduling method and device, equipment and a storage medium, and the method comprises the steps: when a pod event is monitored, scheduling a storage volume corresponding to the pod event based on the attribute information of each node storage pool in a cluster, and determining the storage pool to which the storage volume is scheduled on each node; deducting the capacity consumed by scheduling the storage volume in a storage pool of each node to obtain remaining available storage resources in the storage pool; and determining a target node to which the pod event is scheduled based on the attribute information of the available storage resources. According to the technical scheme provided by the embodiment of the invention, controllable management and scheduling of storage resources of the cloud platform system can be ensured, node storage resource fragments are reduced, and the cluster storage utilization rate is improved.

Description

technical field [0001] Embodiments of the present invention relate to resource scheduling technologies, and in particular, to a storage resource scheduling method, device, device, and storage medium. Background technique [0002] In the container cloud platform system, the storage system is divided into two types according to the deployment method: external storage system and local storage system. The external storage system is physically isolated from the cloud platform system, and the business process on the cloud platform system accesses the storage system through the network protocol; the local storage system and the cloud platform system are deployed in the same physical cluster, and the business in the cloud platform system directly accesses the local through the IO stack Storage System. Due to the limitation of network bandwidth, compared with external storage systems, local storage systems have obvious advantages in data read and write speeds, so they have become co...
