OpenStack Magnum可扩展容器网络方案设计与实现

Design and implementation of scalable container network policy of OpenStack Magnum

在云计算领域随着以Docker为代表的容器引擎与以Kubernetes为代表的容器编排引擎的不断成熟,容器技术越来越火热。包括Google、Amazon、阿里巴巴在内的众多公司都开始在云平台上提供容器服务。文章基于开源云平台OpenStack,通过分析Magnum的流程与原理,对其容器网络方案可扩展性不足的问题做出了改进。通过对容器网络插件的部署方式进行重构,将容器网络插件配置与容器集群配置之间解耦,完善了magnum容器网络的可扩展性。最后通过创建不同容器网络的集群对方案进行验证。

In the field of cloud computing,container technology has become increasingly hot with container runtime environments represented by docker and container orchestration engines represented by Kubernetes. Many companies like Google,Amazon and Alibaba have provided container services on their cloud platforms. This article is based on the open source cloud platform OpenStack,analyzing the processes and principles of Magnum,improves the scalability of the container network solution. Through reconstructing the deployment of supported container network plugins,the configuration of container network plugins are decoupled from the basic configuration of the container cluster,which improves the scalability of the magnum container network solution. Finally,verify the solution by creating a cluster of different container networks.
