CoSky 高性能、低成本微服务治理平台(服务注册/发现 & 配置中心)

License GitHub release Maven Central Codacy Badge codecov Integration Test Status

English Document

CoSky 是一个轻量级、低成本的服务注册、服务发现、 配置服务 SDK,通过使用现有基础设施中的 Redis (相信你已经部署了Redis),不用给运维部署带来额外的成本与负担。 借助于 Redis 的高性能, CoSky 提供了超高TPS&QPS (10W+/s JMH 基准测试)。CoSky 结合本地进程缓存策略 + Redis PubSub,实现实时进程缓存刷新,兼具无与伦比的QPS性能 (7000W+/s JMH 基准测试)、进程缓存与 Redis 的实时一致性。

服务注册与发现

REST-API Server (Optional)

安装 REST-API Server

方式一:下载可执行文件

下载 cosky-server

解压 cosky-lastVersion.tar

cd cosky-lastVersion
# 工作目录: cosky
bin/cosky --server.port=8080 --spring.data.redis.uri=redis://localhost:6379

方式二:在 Docker 中运行

docker pull ahoowang/cosky:lastVersion
docker run --name cosky -d -p 8080:8080 --link redis -e SPRING_DATA_REDIS_URL=redis://redis:6379  ahoowang/cosky:lastVersion

方式三:在 Kubernetes 中运行

CoSky-Dashboard

服务依赖拓扑

CoSky-Dashboard-topology

基于角色的访问控制(RBAC)

  • cosky: 保留用户名,超级用户,拥有最高权限。应用首次启动时会初始化超级用户(cosky)的密码,并打印在控制台。忘记密码也不用担心,可以通过配置 enforce-init-super-user: trueCoSky 会帮助你重新初始化密码并打印在控制台。
---------------- ****** CoSky -  init super user:[cosky] password:[6TrmOux4Oj] ****** ----------------
  • admin: 保留角色,超级管理员角色,拥有所有权限,一个用户可以绑定多个角色,一个角色可以绑定多个资源操作权限。
  • 权限控制粒度为命名空间,读写操作
