Abstract: In the field of cloud computing, optimization of resource management and task scheduling is crucial to improving system efficiency and resource utilization. As the industry's leading container orchestration tool, Kubernetes (K8S) is dedicated to the automated deployment, expansion and management of application containers. One of its core advantages is to use efficient scheduling algorithms to achieve cross-cluster deployment and execution of containers. This strategy plays an important role in application system portability, security, optimized resource utilization and integrated deployment, making it more agile and efficient in responding to changing business needs. In view of this, K8S scheduling algorithms have become a hot research topic in the industry. This article aims to comprehensively investigate and analyze K8S-related scheduling algorithms and their actual performance in different application fields, with special attention to three areas: improvement of general scheduling algorithms , artificial intelligence-oriented scheduling strategy and elastic scaling-based scheduling technology. Finally, through comprehensive analysis, the shortcomings of current research and issues that need to be solved in future research are revealed, providing reference for further optimizing the K8S scheduling algorithm.

引言
Kubernetes(簡稱K8S)是一款開源容器編排平臺,目標(biāo)是簡化和自動化容器化應(yīng)用程序的部署、擴展及運維流程。該平臺提供了一整套強大的工具,助力開發(fā)者和運維團隊在分布式環(huán)境中高效管理應(yīng)用程序。Kubernetes的主要功能包括容器編排、自動化部署、自動擴展、負(fù)載均衡、容錯和自我修復(fù)等。它能夠根據(jù)應(yīng)用程序的資源需求和可用資源自動安排容器,確保資源使用高效且均衡。K8S通過水平自動擴展功能,根據(jù)實際負(fù)載自動增減容器實例,有效應(yīng)對不同的流量需求。此外,該平臺還支持容器的自動恢復(fù)和滾動更新,保障應(yīng)用程序的高可用性和業(yè)務(wù)的連續(xù)性。作為業(yè)界先進的容器編排平臺,K8S為開發(fā)者和運維人員提供了一種高效、靈活且可擴展的部署和管理容器化應(yīng)用程序的方式,極大地簡化了分布式應(yīng)用的管理和維護工作。K8S非常適合用于構(gòu)建基于微服務(wù)的Web應(yīng)用程序,其中每個功能組件都能在其獨立的容器中運行。
