1，背景
在docker中部署spark服务和调用spark服务的微服务，微服务之间通过fegin调用
2，问题，docker容器中服务器来后，注册中心都有，调用服务也正常，但是调用spark启动任务后报错，报错信息

3，分析
HeartbeatReceiver@pinganan_datastudio_pinganan-scheduler-worker.1.n9zf1yk8znety8x2lw2pzn9a8.db2_net这个是中pinganan-scheduler-worker这个服务在注册中心的虚拟域名，解析不到这个域名，
注册中心的服务信息
```java
pinganan_datastudio_everdc-scheduler-worker.1.n9zf1yk8znety8x2lw2pzn9a8.db2_net:pinganan-scheduler-worker:8080 【11.10.33.67】
4，尝试将这个服务注册的ip在编排文件中指定这个服务的ip
environment:
- eureka.instance.prefer-ip-address=true
- eureka.instance.ip-address=192.168.10.224
- eureka.instance.non-secure-port=8080
5，运行后报错
调用5park执行引擎服务出错:
feign.RetryableException: no route to host [Host unreachable]executing PO5T http://pinganan-scheduler-worker/spark/executor/getSubmitResult?applicationПame=
pinganan-data-studio&modelRunld=12 at feign.FeignException.errorExecuting[FeignExcep
tion.java:249]~
6，分析上面问题
这样制定后，其他服务fegin调用失败，找不到这个服务，只能再改回去
7，尝试在spark提交任务中指定driver的ip，spark.driver.host=11.10.33.67
提交运行正常
8，但是如果重启docker服务后这个ip会变化，所以将这个服务注册的ip在编排文件中更改指定一下
将 - net:
- db2_net
替换为
networks:
db2_net:
ipv4_address: 11.10.13.67
9，重启任务后，提交任务正常
