CoSky 高性能 服务注册/发现 & 配置中心

CoSky 基于 Redis 的服务治理平台（服务注册/发现 & 配置中心）

Consul + Sky = CoSky

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、进程缓存与 Redis 的实时一致性。

REST-API Server (Optional)

安装 REST-API Server

方式一：下载可执行文件

下载 rest-api-server

解压 cosky-rest-api-1.0.0.tar

cd cosky-rest-api-1.0.0
# 工作目录: cosky-rest-api-1.0.0
bin/cosky-rest-api --server.port=8080 --cosky.redis.uri=redis://localhost:6379

方式二：在 Docker 中运行

docker pull ahoowang/cosky-rest-api:1.0.0
docker run --name cosky-rest-api -d -p 8080:8080 --link redis -e COSKY_REDIS_URI=redis://redis:6379  ahoowang/cosky-rest-api:1.0.0
