micro
实现功能
- 链路跟踪
gateway-api -> api -> grpc
- 日志
访问日志、业务日志: 增加 Trace-Id 字段
- etcd配置中心
micro etcd配置库功能进行封装，动态更新配置增加HookFunc功能
- 其他主要功能
熔断
prometheus监控
内部服务采用grpc通信
环境准备
- jaeger部署
docker run -d --name jaeger -e COLLECTOR_ZIPKIN_HTTP_PORT=9411 -p 5775:5775/udp -p 6831:6831/udp -p 6832:6832/udp -p 5778:5778 -p 16686:16686 -p 14268:14268 -p 9411:9411 jaegertracing/all-in-one:1.6
- etcd部署
