HttpException：-404 无法连接到 mac 上的远程服务器，而运行 Docker

Question

我得到 Error HttpException: -404 Failed to connect to remote server 而运行来自 docker 的 jar 文件执行命令 docker exec -it Test_docker java -jar TestDocker.jar.

Note: I have created docker on windows, Where my docker machine IP is 192.168.99.100 and my docker exec command running successfully.I am accessing SPARQL endpoint on windows using URL: http://192.168.99.100:8890/sparql this will work perfectly. But when I am using same on mac it will give me an error which I mention above. I have also try to change SPARQL endpoint on my code as http://localhost:8890/sparql but not work well though it will work fine on chrome browser on mac while executing through command it will giving me an error.

这是我的 docker-compose 文件，

version: "3"
services:
  jardemo_test:
    container_name: Test_docker
    image: "java:latest"
    working_dir: /usr/src/myapp
    volumes:
      - /docker/test:/usr/src/myapp    
    tty: true
    depends_on:
      - virtuoso

  virtuoso:
    container_name: virtuoso_docker
    image: openlink/virtuoso_opensource
    ports:
      - "8890:8890"
      - "1111:1111"
    environment:      
      DB_USER_NAME: dba
      DBA_PASSWORD: dba
      DEFAULT_GRAPH: http://localhost:8890/test
    volumes:
      - /docker/virtuoso-test/:/data

Note: I have tried all the way to set the environment variable on docker-compose file default graph URL with all the IP address but it won't allow.Which IP I have tried all combination listed below. Though I am getting the same error.

DEFAULT_GRAPH: http://localhost:8890/test
DEFAULT_GRAPH: http://127.0.0.1:8890/test
DEFAULT_GRAPH: http://0.0.0.0:8890/test

下面是我的 docker-compose ps 结果，

 $ docker-compose ps
 Name                    Command               State                       Ports
---------------------------------------------------------------------------------------------------------
Test_docker      /bin/bash                        Up
virtuoso_docker   /opt/virtuoso-opensource/b ...   Up      0.0.0.0:1111->1111/tcp, 0.0.0.0:8890->8890/tcp

下面是我正在使用的代码，

QueryExecution qexec = QueryExecutionFactory.sparqlService("http://localhost:8890/sparql", queryString);
ResultSet results1 = qexec.execSelect();

Info: After running successful docker I have accessed the http://localhost:8890/sparql. it will successfully run on the mac.

有人可以帮我解决这个问题吗？另外，欢迎您提出建议，thought.Thanks 提前获得帮助和时间。

根据我同事的建议，问题是 docker 文件中的代码将 docker 视为本地主机。 IP-address 192.168.99.100 也不知道，因为 mac 没有。为了解决连接问题，docker使用自己的network.Thedocker-compose服务名称作为参考。因此，不要使用 http://localhost:8890/sparql, you should use http://virtuoso:8890/sparql，因为 virtuoso 是服务名称。

我试过了，它会解决我的问题。
