# 微服务镜像集成代理

# README

#SkyWalking 链路追踪版本
##准备
1. 把构建好的jar复制到files/jars目录下  
2. 下载sentinel-dashboard-1.8.4.jar包复制到files/jars目录下  
   改名sentinel-dashboard.jar
   [https://github.com/alibaba/Sentinel/releases] 
3. 下载代理Java Agent[apache-skywalking-java-agent-8.10.0.tgz],放到files目录下,与Dockerfile同级  
   改名apache-skywalking-java-agent.tgz
   [http://skywalking.apache.org/downloads]    
   [https://www.apache.org/dyn/closer.cgi/skywalking/java-agent/8.10.0/apache-skywalking-java-agent-8.10.0.tgz]    

##启动
docker-compose up -d
##只构建镜像
docker-compose build
##区别
1. 使用代理
2. 启动前需指定收集器服务的地址   
   -Dskywalking.collector.backend_service=192.168.213.201:11800

## 使用本地IDEA启动
配置vm参数：
```
-javaagent:E:\Code\package\skywalking\skywalking-agent\skywalking-agent.jar
-Dskywalking.agent.service_name=ok-auth
-Dskywalking.collector.backend_service=192.168.213.201:11800
```
