Abstract

The invention provides a container cloud elastic scaling method and device. The device comprises a micro-service, a cluster node resource, an automatic scaling controller, a node controller and a node resource pool. The method comprises the following steps: judging whether the resource utilization rate of the micro service meets a preset capacity expansion condition or not, if so, calculating resources required by capacity expansion, judging whether residual nodes in cluster node resources meet the resources required by capacity expansion or not, and if not, calculating a minimum specification required by capacity expansion according to the resources required by capacity expansion; and selecting a node meeting the minimum specification from the node resource pool as a new node according to a minimum specification request required by capacity expansion, and adding the new node into cluster node resources. The node expansion is realized in advance by automatically monitoring the cluster state and the current resource utilization rate of the micro-service, the two-stage elastic capacity expansion and shrinkage are realized, the rapid capacity expansion is realized, the business requirements are better met, the capacity is automatically reduced after the service flow is reduced, and the cost is saved.

Description

technical field [0001] The present application relates to the field of network technology, and in particular to a method and device for container cloud elastic scaling. Background technique [0002] Under the Kubernetes-based container cloud cluster, a large number of microservices are managed and scheduled. Each microservice can have multiple instances (pods), which run distributedly on multiple nodes (Nodes) of the cloud platform in the form of containers. There are inevitably some peak periods in the application. With the sudden increase in business volume, it is difficult for microservice instances to cope with the increased traffic. [0003] Kubernetes has the function of horizontal pod autoscaling (Horizontal Pod Autoscaling, HPA). HPA obtains the monitoring indicator data of the utilization rate of microservice resources through the resource monitoring system in the cluster, compares the monitoring indicator data with the preset threshold, and when it exceeds the pres...
