jaeger 使用ElasticSearch 作为后端存储

jaeger 使用ElasticSearch 作为后端存储

jaeger 支持es 作为后端存储，这样对于查询、以及系统扩展是比较方便的

使用docker-compose 运行

环境准备

参考项目： https://github.com/rongfengliang/nginx-opentracing-demo

• docker-compose file

• 说明
  主要是通过环境变量指定存储类型以及es 服务器集群的地址,注意对于依赖关系需要有一个单独的服务

启动&&测试

• 启动

docker-compose up -d

• 效果
  
  
  
  

说明

关于依赖的显示，需要使用spark-dependencies处理，参考docker-compose file
同时需要配置为定时任务
