# Kratos
|
|
|
|
|
|
|
|
Kratos是[bilibili](https://www.bilibili.com)开源的一套Go微服务框架,包含大量微服务相关框架及工具。
|
|
|
|
|
|
|
|
> 名字来源于:《战神》游戏以希腊神话为背景,讲述由凡人成为战神的奎托斯(Kratos)成为战神并展开弑神屠杀的冒险历程。

|
|
|
## Goals
|
|
|
|
|
|
|
|
我们致力于提供完整的微服务研发体验,整合相关框架及工具后,微服务治理相关部分可对整体业务开发周期无感,从而更加聚焦于业务交付。对每位开发者而言,整套Kratos框架也是不错的学习仓库,可以了解和参考到[bilibili](https://www.bilibili.com)在微服务方面的技术积累和经验。

## Features
|
|
|
|
* HTTP Blademaster:核心基于[gin](https://github.com/gin-gonic/gin)进行模块化设计,简单易用、核心足够轻量;
|
|
|
|
* GRPC Warden:基于官方gRPC开发,集成[discovery](https://github.com/bilibili/discovery)服务发现,并融合P2C负载均衡;
|
|
|
|
* Cache:优雅的接口化设计,非常方便的缓存序列化,推荐结合代理模式[overlord](https://github.com/bilibili/overlord);
|
|
|
|
* Database:集成MySQL/HBase/TiDB,添加熔断保护和统计支持,可快速发现数据层压力;
|
|
|
|
* Config:方便易用的[paladin sdk](https://go-kratos.github.io/kratos/#/config),可配合远程配置中心,实现配置版本管理和更新;
|
|
|
|
* Log:类似[zap](https://github.com/uber-go/zap)的field实现高性能日志库,并结合log-agent实现远程日志管理;
|
|
|
|
* Trace:基于opentracing,集成了全链路trace支持(gRPC/HTTP/MySQL/Redis/Memcached);
|
|
|
|
* Kratos Tool:工具链,可快速生成标准项目,或者通过Protobuf生成代码,非常便捷使用gRPC、HTTP、swagger文档;
