Question

我正在尝试通过Dockerfile从使用链接迁移到网络，但我遇到了一些问题。我将首先描绘我的原始设置：

原创 - 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"]

搬运工-compose.yml：

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

新功能 - 网络

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"]

搬运工-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 app（原始情况）中调用我的rest端点时，我总是得到一个响应（一些json数据）。当我现在调用它时，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"
}

来自Devoxx的视频我用作参考：https://youtu.be/aSATsLG59Zs?t=53m33s

似乎我一直做错了，但我不确定它是什么，欢迎任何帮助。提前谢谢！

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

如果将新的（2.0）文件格式用于docker-compose.yml，新的网络功能将从docker-compose 1.6中移出实验，并自动使用。

阅读docker-compose 1.6-rc1的发行说明以获取更多信息; https://github.com/docker/compose/releases/tag/1.6.0-rc1
