Abstract

The invention relates to a Pod scheduling method and system in a Kubernetes cluster. A plurality of working nodes in the cluster form a one-way annular topological structure, the plurality of working nodes comprise a leader node, the leader node communicates with a management plane node, and the Pod scheduling method in the Kubernetes cluster comprises the steps that the leader node pulls a metadata set from the management plane node, so a to-be-operated Pod list is determined; the Pod scheduling operation is carried out on each Pod in the to-be-operated Pod list and the working node in the topological structure of the large node in sequence until the working node for operating the Pod is determined, so the problem that in the related technology, under the condition that the number of the working nodes in the Kubernetes cluster is large, the management plane node bears a bigger scheduling pressure; therefore, an effect of reducing the scheduling pressure of the management plane nodes is achieved.

Description

technical field [0001] The present application relates to the technical field of computer software technology application, in particular to a method and system for pod scheduling in a Kubernetes cluster. Background technique [0002] In a container orchestration engine (Kubernetes, k8s for short) cluster, the scheduler component of the management plane node is responsible for selecting a suitable working node for the Pod to run. The specification of the management plane node needs to be able to support scheduling and management of large-scale working nodes. In terms of technology, the Kubernetes cluster supports a maximum of 5000 working nodes. Within the upper limit of the number of working nodes, in the case of a large number of working nodes in the Kubernetes cluster, the management plane node scheduling pressure is greater. As the number of working nodes increases , the scheduling pressure on the nodes on the management plane is increasing, which may cause the Kubernetes...
