基于kubernetes的计算资源的抢占式调度

Research on Preemptive Scheduling of Computing Resources Based on Kubernetes

基于kubernetes的调度采用先进先出顺序,无法进行优先级调度。针对该问题,设计了Pod抢占式调度,对调度规则和优先级进行划分,采用云计算技术和Docker容器虚拟化技术,搭建实验环境,部署kubernetes高可用集群。采用黑盒测试,验证了此设计能够根据负载变化,达到弹性伸缩和抢占式调度效果。

In kubernetes,the scheduling of the first in first out scheduling is not scheduled,and the Pod preemptive scheduling is designed for the problem.Based on the division of the Pod preemptive scheduling rule and the Pod priority,the Pod preemptive scheduling process is designed.Then,cloud computing technology and docker container virtualization technology are used to build the experimental environment and deploy kubernetes high availability cluster.Finally,the implementation of pod preemptive scheduling verifies that the designed pod can achieve the effect of preemptive scheduling according to the change of loading.
