Embodiment Construction

[0037] Hereinafter, the present application will be described in detail with reference to the drawings and embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0038] figure 1 Shown is the flow chart of the Pod scheduling method in Embodiment 1 of the present application. The Kubernetes system includes a master node and a Node node. The method is applied to the master node of the Kubernetes system and includes the following steps:

[0039] Step 101: Determine the first set of Node nodes;

[0040] In the Kubernetes system, the master node Master manages all Node nodes in the cluster by running the Node Controller component installed on the local machine, and maintains a Node list on the master node Master, which records the status of all Node nodes within the cluster. For related information, the Node Controller checks the health status of the Node ev...

Abstract

The invention discloses a Pod scheduling method and device, and the method comprises the steps: determining a first Node node set, searching an arranged Node node meeting a first preset condition in the first Node node set according to the resource surplus of Node nodes in the first Node node set; determining a second Node set, wherein the second Node set at least does not comprise the arranged Node; selecting a Pod on the arranged Node, and searching the migrated Node meeting a second preset condition in the second Node set according to the resource quantity required for creating the Pod; andif so, scheduling the Pod on the arranged Node node to the migrated Node node. According to the method and the device, the problem of resource fragmentation in the prior art is solved, and cluster resources are saved.

Description

technical field [0001] The present application relates to the technical field of storage management, and in particular to a Pod scheduling method and device. Background technique [0002] Kubernetes (also known as k8s) is Google's open source container cluster management system. It is a complete distributed system support platform with complete cluster management capabilities. At the same time, the Kubernetes system is also a brand-new leading distributed architecture solution based on container technology. Based on Docker technology, it provides containerized applications with a series of complete functions such as deployment and operation, resource scheduling, service discovery, and dynamic scaling. The convenience of large-scale container cluster management. [0003] In terms of cluster management, Kubernetes divides the machines in the cluster into a master node Master and a group of working nodes Node. Among them, the Master node is the management node of the cluster, ...
