spring - Docker-compose从链接迁移到网络MongoDB数据库问题

Question

我正在尝试通过Dockerfile从使用链接的链接迁移到网络，但是遇到一些问题。我将首先概述我的原始设置:

原始-链接

Dockerfile:

FROM java:8
VOLUME /tmp
ADD docker_micro_maven-0.0.1-SNAPSHOT.jar app.jar
RUN bash -c 'touch /app.jar'
EXPOSE 8080
ENTRYPOINT ["java","-Dspring.data.mongodb.uri=mongodb://mongodb/micros", "-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

docker-compose.yml:

mongodb:
 image: mongo
employee:
 image: jdruwe/docker_micro_maven
 links:
  - mongodb
 ports:
  - "8080"

新增-联网

Dockerfile:

FROM java:8
VOLUME /tmp
ADD docker_micro_maven-0.0.1-SNAPSHOT.jar app.jar
RUN bash -c 'touch /app.jar'
EXPOSE 8080
ENTRYPOINT ["java","-Dspring.data.mongodb.uri=mongodb://${MONGO_URI_DOCKER}/micros", "-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

docker-compose.yml:

mongodb:
 container_name: "db"
 image: mongo
employee:
 image: jdruwe/docker_micro_maven
 environment:
  - MONGO_URI_DOCKER=db:27017
 ports:
  - "8080"

当我在spring boot应用程序中调用我的rest端点(原始情况)时，我总是得到响应(一些json数据)。现在调用它时，我得到以下错误响应:

{
  "timestamp": 1453405937191,
  "status": 500,
  "error": "Internal Server Error",
  "exception": "org.springframework.dao.DataAccessResourceFailureException",
  "message": "Timed out after 10000 ms while waiting to connect. Client view of cluster state is {type=Unknown, servers=[{address=db:27017, type=Unknown, state=Connecting, exception={com.mongodb.MongoException$Network: Exception opening the socket}, caused by {java.net.UnknownHostException: db: unknown error}}]; nested exception is com.mongodb.MongoTimeoutException: Timed out after 10000 ms while waiting to connect. Client view of cluster state is {type=Unknown, servers=[{address=db:27017, type=Unknown, state=Connecting, exception={com.mongodb.MongoException$Network: Exception opening the socket}, caused by {java.net.UnknownHostException: db: unknown error}}]",
  "path": "/employee"
}

看来我一直在做错事，但是我不确定是什么，欢迎任何帮助。提前致谢!

在docker-compose 1.5.x中，新网络仍然是一项实验性功能，需要使用--x-networking选项启用。

如果您的docker-compose.yml使用了新的(2.0)文件格式，那么新的联网功能将在docker-compose 1.6中移出实验性功能，并且会自动使用。

阅读docker-compose 1.6-rc1的发行说明以获取更多信息；
