Kubernetes-based container number flexible adjustment implementation method and device

Abstract

The invention provides a kubernetes-based container number flexible adjustment implementation method and device. The method comprises the steps that the access number of different services of the container cluster is acquired; the load condition of each POD of the container cluster is acquired, and the maximum loading service access number of the POD under each service is determined according to the load condition of each POD; the access processable threshold of different services of the POD is determined, the dynamic adjustment mechanism is triggered to adjust the container number when the index of the service access number of the container cluster reaches the set threshold, the POD number required to be adjusted is calculated by monitoring the service request number and the total load condition of the processing service POD, then the POD number is dynamically adjusted according to kubernetes and the POD number is quickly increased at the service peak so as to achieve the effect of shunting and pressure reduction; and excess POD is closed at the service steady period to save the serve resource so that the container operation efficiency and stability can be enhanced, and the resource scheduling efficiency of the Kubernetes-based container clustering management system can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a method and device for implementing elastic scaling based on the number of kubernetes containers. Background technique [0002] Kubernetes is a container-based cluster management system. It mainly includes components such as Service, ReplicationController, and Pod. It is built on containers such as Docker. It provides functions such as application deployment, maintenance, and expansion mechanisms. Using Kubernetes can easily manage containers running across machines. application. Deployment is the core management process of kubernetes. It is responsible for managing the entire life cycle of POD (another name for containers in the kubernetes system). The number of PODs can be customized in the definition script of deployment. Through the automatic detection mechanism, the number of PODs in the kubernetes system is consistent. maintained at a defined quantity. Wh...

Problems solved by technology

The automatic detection mechanism of the deploment definition script only maintains the number of PODs through the numbers defined in the script, and cannot dynamically adjust the number of PODs according to the fluctuation of business pressure.
