英文:
How to connect to external service from an Application deployed on docker?
问题
以下是翻译好的内容：
我有一个应用程序，该应用程序正在使用嵌入式JanusGraph服务器。
当该应用程序直接部署在服务器（裸金属）上时，应用程序运行良好。
然而，当我在Docker上运行映像时，我遇到连接错误。
这是我使用的Docker文件：
FROM *****.ecr.us-east-1.***.com/java8:latest
ADD my-api/target/my-api-0.0.4-FINAL.zip /opt/
WORKDIR /opt/
RUN unzip my-api-0.0.4-FINAL.zip
WORKDIR /opt/my-api-0.0.4/bin/
RUN chmod +x /opt/my-api-0.0.4/bin/runserverscript.sh
RUN mkdir /data
EXPOSE 8181
CMD exec /opt/my-api-0.0.4/bin/runserverscript.sh
这是我连接到外部数据库的JanusGraph配置：
storage.backend=cql
storage.cql.keyspace=a_graph
storage.cql.read-consistency-level=ONE
storage.hostname=10*.**.2.**
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-size = 0.5
cache.db-cache-time = 180000
我使用以下命令创建映像：
docker build --tag my-api:latest .
并使用以下命令运行容器：
docker run --publish 7171:7171 --name myapi my-api:latest
并且出现了以下连接问题：
正在加载...图配置：ja-staging.properties 无法启动服务器，错误：创建bean时出错，bean名称为 ''：注入自动装配的依赖项失败；嵌套异常是 org.springframework.beans.factory.BeanCreationException：无法自动装配字段：私有XXXService XXXService；嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建bean时出错，bean名称为 'followService'：注入自动装配的依赖项失败；嵌套异常是 org.springframework.beans.factory.BeanCreationException：无法自动装配字段：私有gggService gService；嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建bean时出错，bean名称为 'graphService'：调用init方法失败；嵌套异常是 java.lang.IllegalArgumentException：无法实例化实现：org.janusgraph.diskstorage.cql.CQLStoreManager
英文:
I have an application which is using an embedded janusgraph server.
The application is running fine when it is deployed directly on the server (bare metal).
However, i am getting connection error when i run the image on docker.
Here is the docker file, which i am using:
FROM *****.ecr.us-east-1.***.com/java8:latest
ADD my-api/target/my-api-0.0.4-FINAL.zip /opt/
WORKDIR /opt/
RUN unzip my-api-0.0.4-FINAL.zip
WORKDIR /opt/my-api-0.0.4/bin/
RUN chmod +x /opt/my-api-0.0.4/bin/runserverscript.sh
RUN mkdir /data
EXPOSE 8181
CMD exec /opt/my-api-0.0.4/bin/runserverscript.sh
and here is the janusgraph config: (which i connecting to external db)
storage.backend=cql
storage.cql.keyspace=a_graph
storage.cql.read-consistency-level=ONE
storage.hostname=10*.**.2.**
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-size = 0.5
cache.db-cache-time = 180000
I am creating the image using the following command:
docker build --tag my-api:latest .
and running the container using:
docker run --publish 7171:7171 --name myapi my-api:latest
and getting the connect issue as follows:
> Loading.. Graph Config : ja-staging.properties Server could not be

重新在我的 Mac 机器上安装 Docker 解决了我的问题。
我不知道为什么会发生这种情况。但在经过几天的困扰后，我重新安装了 Docker，一切都正常工作了。
英文:
Re-installing the docker from my mac machine resolved the issue for me.
I am not why it was happening. But after a couple of days of struggler, i re-installed the docker, and all worked fine.
