我有一个jar在我的主机上运行良好；具体来说，当我跑步时
java -jar myjar.jar
我得到预期的输出：
[2018-12-05 16:46:53.917] boot - 21252 INFO [main] --- 应用程序：没有活动配置文件集，回退到默认配置文件：默认
[2018-12-05 16:47:00.855] boot - 21252 INFO [main] --- 应用程序：在 8.176 秒内启动应用程序（JVM 运行时间为 9.106）
这就是核心数据微服务。
[2018-12-05 16:47:00.856] boot - 21252 INFO [main] --- 应用程序：注册事件队列

[2018-12-05 16:47:00.915] boot - 21252 INFO [main] --- ZeroMQEventSubscriber：正在监视新的事件消息...
但后来，我尝试运行相同的jar在 docker 容器内。所以我创建这样的图像：
FROM openjdk:8-jdk-alpine
COPY myjar.jar /opt/spring-cloud/lib/
ENTRYPOINT ["/usr/bin/java"]
CMD ["-jar", "/opt/spring-cloud/lib/myjar.jar"]
EXPOSE 48080
并运行它：
sudo docker run [ID]
但这一次，我从容器日志中得到了这个异常（这只是异常的一部分，因为它太大了，但如果需要的话我可以显示全部）：
[2018-12-07 08:30:31.447] boot - 1 INFO [main] --- Application: No active profile set, falling back to default profiles: default
[2018-12-07 08:32:35.423] boot - 1 ERROR [main] --- SpringApplication: Application startup failed

Mongo 已通过 docker-compose 在另一个容器中启动（与其他容器中的其他服务一起）：
ps aux | grep mongo
root 16226 0.0 0.0 4340 768 ? Ss 10:27 0:00 /bin/sh -c /edgex/mongo/config/launch-edgex-mongo.sh
root 16292 0.0 0.0 4340 764 ? S 10:27 0:00 /bin/sh /edgex/mongo/config/launch-edgex-mongo.sh
root 16293 0.5 0.3 961168 61400 ? SLl 10:27 0:05 mongod --smallfiles
这是 docker-compose 文件：

.... more services...

以及 mongo db 配置属性：
spring.data.mongodb.username=core
spring.data.mongodb.password=password
spring.data.mongodb.database=coredata
#change to localhost when running locally during development
# (or set hosts to point edgex-mongo to the mongo host
spring.data.mongodb.host=localhost
#spring.data.mongodb.host=edgex-mongo
spring.data.mongodb.port=27017
spring.data.mongodb.connectTimeout=120000
spring.data.mongodb.socketTimeout=60000
spring.data.mongodb.maxWaitTime=120000
spring.data.mongodb.socketKeepAlive=true
有什么想法可能出了什么问题吗？
