摘　　要：轻量级虚拟化技术Docker及Docker集群管理工具Swarm的出现,为基于Linux平台的集群资源虚拟化提供了一套简单高效的解决方案。但是,能否充分发挥一个集群的整体性能,一个好的调度策略至关重要。目前Swarm工具内置的调度策略都无法很好地实现Docker集群的负载均衡,并且对集群资源的利用率不高,造成了很大的资源浪费。针对以上问题,文中利用权值调度算法对Docker Swarm集群的调度策略进行了优化,最终很好地实现了集群的负载均衡,充分发挥出了集群中每一个节点的性能,并提高了集群的整体性能。The emergence ol Docker,which is a lightweight virtualization technology,and the Dockercluster management tool named Swarm provides a simple and efficient solution lor resource virtualizationol clusters based on Linux platform. But, if it can play the overall performance of a cluster, a goodscheduling strategy is very important. Currently,each ol the scheduling strategy built-in Swarm cannotrealize load balancing ol the cluster very well,and the utilization rate ol the cluster resources is not high,which caused great waste ol resources. To solve the above problems,this paper optimizes the schedulingpolicy ol Docker Swarm cluster by the weight scheduling algorithm, which has given lull play to theperlormance ol each node and has realized the load balancing and improved the perlormance ol thecluster.
