Main Features

Crane Overview

成本可视化和优化评估

  • 提供一组 Exporter 计算集群云资源的计费和账单数据并存储到你的监控系统,比如 Prometheus。
  • 多维度的成本洞察,优化评估。通过 Cloud Provider 支持多云计费。

推荐框架

提供了一个可扩展的推荐框架以支持多种云资源的分析,内置了多种推荐器:资源推荐,副本推荐,闲置资源推荐。了解更多

基于预测的水平弹性器

EffectiveHorizontalPodAutoscaler 支持了预测驱动的弹性。它基于社区 HPA 做底层的弹性控制,支持更丰富的弹性触发策略(预测,观测,周期),让弹性更加高效,并保障了服务的质量。了解更多

负载感知的调度器

动态调度器根据实际的节点利用率构建了一个简单但高效的模型,并过滤掉那些负载高的节点来平衡集群。了解更多

基于 QOS 的混部

QOS相关能力保证了运行在 Kubernetes 上的 Pod 的稳定性。具有多维指标条件下的干扰检测和主动回避能力,支持精确操作和自定义指标接入;具有预测算法增强的弹性资源超卖能力,复用和限制集群内的空闲资源;具备增强的旁路cpuset管理能力,在绑核的同时提升资源利用效率。了解更多

架构

Crane 的整体架构如下:

Crane Overview

Craned

Craned 是 Crane 的最核心组件,它管理了 CRDs 的生命周期以及API。Craned 通过 Deployment 方式部署且由两个容器组成:

  • Craned: 运行了 Operators 用来管理 CRDs,向 Dashboard 提供了 WebApi,Predictors 提供了 TimeSeries API
  • Dashboard: 基于 TDesign's Starter 脚手架研发的前端项目,提供了易于上手的产品功能

Fadvisor

Fadvisor 提供一组 Exporter 计算集群云资源的计费和账单数据并存储到你的监控系统,比如 Prometheus。Fadvisor 通过 Cloud Provider 支持了多云计费的 API。

Metric Adapter

Metric Adapter 实现了一个 Custom Metric Apiserver. Metric Adapter 读取 CRDs 信息并提供基于 Custom/External Metric API 的 HPA Metric 的数据。

Crane Agent

Crane Agent 通过 DaemonSet 部署在集群的节点上。
