FabEdge

main Releases license

FabEdge是一个基于kubernetes构建的,专注于边缘计算的容器网络方案,支持KubeEdge/SuperEdge/OpenYurt等主流边缘计算框架。 FabEdge旨在解决边缘计算场景下网络管理复杂,跨集群通信困难,缺少能自动感知网络拓扑的服务发现等问题,使能云边、边边业务协同。FabEdge支持4/5G,WiFi等弱网环境,适用于物联网,车联网、智慧城市等场景。

FabEdge不仅支持边缘节点(通过KubeEdge等边缘计算框架加入集群的远程节点),还支持边缘集群(独立的K8S集群)。

FabEdge是托管在CNCF下的沙箱项目。

特性

  • 自动地址管理:自动管理边缘节点网段,自动管理边缘容器IP地址。
  • 云边、边边协同: 建立云边,边边安全隧道,使能云边,边边之间的业务协同。
  • 灵活的隧道管理: 使用自定义资源“社区”,可以根据业务需要灵活控制边边隧道。
  • 拓扑感知路由: 使用最近的可用服务端点,减少服务访问延时。

优势

  • 标准: 遵从K8S CNI规范,适用于任何协议,任何应用 。
  • 安全: 使用成熟稳定的IPSec技术,使用安全的证书认证体系。
  • 易用: 使用Operator机制,自动管理地址,节点,证书等,最大程度减少人为干预。

工作原理

fabedge-arch
  • KubeEdge等边缘计算框架建立了控制面,把边缘节点加入云端K8S集群,使得可以在边缘节点上下发Pod等资源;FabEdge在此基础上建立了一个三层的数据转发面,使得Pod和Pod之间可以直接通讯。
  • 云端可以是任何K8S集群,目前支持的CNI包括Calico, Flannel。
  • FabEdge使用安全隧道技术,目前支持IPSec。
  • FabEdge包括的组件:Operators, Connector,Agent和Cloud-Agent。
  • Operator运行在云端任意的节点,通过监听节点,服务等K8S资源,为每个Agent维护一个ConfigMap,包括了本Agent需要的路由信息,比如子网,端点,负载均衡规则等,同时为每个Agent维护一个Secret,包括CA证书,节点证书等。Operator也负责Agent自身的管理,包括创建,更新,删除等。
  • Connector运行在云端选定的节点,负责管理从边缘节点发起的隧道,在边缘节点和云端集群之间转发流量。从Connector节点到云端其它非Connector节点的流量转发仍然依靠云端CNI。
  • Cloud-Agent运行在集群中所有非边缘,非Connector的节点,它负责管理本节点到远端的路由。
  • Agent运行在每个边缘节点上, 它使用自己的ConfigMap和Secret的信息,发起到云端Connector和其它边缘节点的隧道,负责本节点的路由,负载均衡,iptables规则的管理。
  • Fab-DNS运行在所有FabEdge的集群里,它通过截获DNS请求,提供拓扑感知的跨集群服务发现能力。

FabEdge和传统CNI的区别

FabEdge和现有的CNI,比如Calico,Flannel,互为补充,解决不同的问题。就像前面架构图所示,Calico等传统的插件运行在云端K8S集群里,负责云内节点之间的流量转发,FabEdge作为它的一个补充,把网络的能力延伸到了边缘节点和边缘集群,使能了云边,边边通讯。
