boot版的Prod与docker-compose遇到配置问题的情况

#blade配置
blade:
  prop:
    upload-domain: http://localhost:8888
    remote-mode: true
    remote-path: /usr/share/nginx/html
    log-mode: true

1、这个部分是做什么用的？

2、在Docker容器里面情况可能是访问不到nginx容器或者无法正常获取nginx路径，这个怎么处理？

另外问题：docker-compose

这个配置问题是，每个容器都是不固定IP导致那些容器无法互通

 比如ant.design.pro配置localhost:9999 这个访问不到另一个flow容器
