关于thanos的介绍可以参考这篇官方博客的翻译文档,本文不作部署操作介绍。下图是thanos的官方架构图,主要有5个组件:
通常thanos管理多集群时,除Sidecar组件需要在每个集群内部署,其余组件仅部署一份,用于处理多个集群的数据。需要注意的是,thanos的StoreAPI采用的是gRPC协议,只能走四层通信,像在openshift 3.11版本下无法通过router(ingress)暴露给集群外部的Query等组件。规避办法为采用nodePort方式暴露,但通常nodePort并不是一个很好的方式,因为它占用了主机的端口。
从使用上看,thanos使用上最主要的作用就是实现了数据的持久化以及历史数据的提取,其实现的StoreAPI也可以作为可移植的功能。
