docker+apollo+springcloud部署问题

在linux环境部署springcloud项目，如果不使用docker部署，正常启动，完全没有问题，可成功启动。 但是一旦使用docker部署springcloud，就报错，原因自己猜测是不是因为，docker没有办法读取/opt/settings/server.properties，还是docker的java环境需要设置？ 部分日志如下： 2019-08-08 07:20:33.327 INFO 1 --- [ main] c.c.f.f.i.p.DefaultApplicationProvider : App ID is set to renren-cloud by app.id property from System Property 2019-08-08 07:20:33.355 INFO 1 --- [ main] c.c.f.f.i.p.DefaultServerProvider : Environment is set to null.
