在这里探索云原生
推动上下游生态协作,开启边缘设备的云原生管理能力
2021年11月16日

近期,OpenYurt 发布了 v0.5.0 版本。在新发布版本中首次提出 kubernetes-native非侵入、可扩展的边缘设备管理标准,使 Kubernetes 业务负载模型和 IOT 设备管理模型无缝融合。同时联合 VMware 推动 EdgeX Foundry 作为云原生设备管理模型的首个实现并成功落地,大大降低 EdgeX Foundry 在 Kubernetes 上的部署管理的复杂度同时也提升了边缘设备的管理效率。

|边缘设备的云原生管理特点|

当使用 Kubernetes 来解决边缘计算场景的需求时,现有的解决方案要么改变系统架构(如将控制平面和 kubelet 打包在一起),要么重度修改核心组件(如kubelet 中糅合设备管理)。

受 Unix 哲学:“做一件事,做好它”(Do one thing and do it well)的启发,OpenYurt 社区认为 Kubernetes 应该专注于计算资源和业务容器的管理,而边缘设备管理可以通过采用现有的边缘计算平台来完成。

因此,OpenYurt 社区定义了通用的 Kubernetes CRDs,它们充当 OpenYurt 和边缘平台之间的中介。通过为这些 CRDs 实现自定义控制器,任何现有的边缘平台(如 EdgeX Foundry)都可以集成到 OpenYurt 中。同时这些 CRDs 允许用户以声明式的方式管理边缘设备,这为用户提供了 Kubernetes-native 的边缘设备管理体验。

因此,边缘设备的云原生管理特点可以总结为:Kubernetes-native 方式管理,非侵入模式集成,无边缘计算平台绑定。

 

|Kubernetes-native 方式管理边缘设备|

边缘设备的云原生管理能力主要包括以下几个要点:

● Kubernetes 业务负载模型与边缘设备管理模型的无缝融合;

● Kubernetes-native 方式管理边缘设备;

● EdgeX Foundry 作为 OpenYurt 社区第一个融合的 IoT 解决方案,共同探索了一条开放标准的 IoT、云原生融合方案;

首先引入 yurt-edgex-manager 组件,主要用于在 OpenYurt 集群中从节点池维度来管理 EdgeX Foundry 的生命周期(包括安装部署,删除,更新)。用户只需要通过简单编辑的 EdgeX CRD 就可以轻松的管理 EdgeX Foundry 系统。推荐以节点池为维度部署 EdgeX Foundry 系统。原理如下所示:

其次引入 yurt-device-controller 组件,它是 Kubernetes 系统和边缘计算平台(如 EdgeX Foundry)的联结器,使用户可以通过 Kubernetes CRs 来管理边缘设备。一个 yurt-device-controller 实例对应一个节点池的 EdgeX Foundry。整体部署架构如下:

|总结|

OpenYurt 与 EdgeX Foundry 的融合完全是基于开源社区的运作机制逐步讨论并落地实现的,由 VMware,阿里云等公司主导,社区成员充分参与讨论而成型的。在整个项目的落地过程中,进一步完善了 OpenYurt 社区的开源治理流程与机制,更好的推动了边缘计算领域的上下游生态协作。

多个项目的并行设计与开发,让大家更好的体验到'Kubernetes-native, 非侵入,可扩展'等设计理念的优势,也为边缘设备的云原生管理能力落地以及后续演进提供了基础保障。目前已经有不少社区成员在试用该能力,同时 OpenYurt 社区也在陆续推出相关能力的 Demo 视频。

OpenYurt 新版本中重点提升了原生 Kubernetes 在边缘场景的设备管理能力,同时也优化和完善边缘场景的治理能力,后续 OpenYurt 社区会在边缘设备管理,项目易用性,单元化治理能力等方面持续投入。
