我有一个 jar
在我的主机上运行良好;具体来说,当我运行时
java -jar myjar.jar
我得到了预期的输出:
[2018-12-05 16:46:53.917] boot - 21252 INFO [main] --- Application: No active profile set, falling back to default profiles: default
[2018-12-05 16:47:00.855] boot - 21252 INFO [main] --- Application: Started Application in 8.176 seconds (JVM running for 9.106) This is the Core Data Micro Service.

[2018-12-05 16:47:00.915] boot - 21252 INFO [main] --- ZeroMQEventSubscriber: Watching for new Event messages...
但是,我尝试在 docker 容器中运行相同的
jar
。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]
但是这一次,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,但如果需要我可以全部显示出来):
[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 已经通过 docker-compose 在另一个容器中启动(连同其他容器中的其他服务):
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

和 mongo db 配置属性:

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
任何想法可能出了什么问题?
最佳答案
这里有两个问题,首先 spring 尝试在 localhost
上连接到您的 mongodb ,在 docker 中这不起作用,因为 localhost
对当前容器的引用,当然没有可用的 mongodb。要解决此问题,您必须注释掉这一行并取消注释将主机列为 edgex-mongo
的下一行它与您的 mongodb 容器的主机名相对应,因此 spring 知道连接到该容器。
但是,当您这样做时,您会遇到无法识别 edgex-mongo
的问题。因为它与这个容器没有任何联系。 edgex-mongo
位于桥接网络中,需要您使用以下命令将 spring 容器添加到此网络:docker run --network edgex--network [image]
我希望这可以帮助你
