Docker-compose 拒绝连接到 localhost答案

【问题标题】：Docker-compose refuses to connect to localhostDocker-compose 拒绝连接到 localhost
【发布时间】：2020-03-13 11:20:55
【问题描述】：

我的 dockerized webapp 有问题。基本上我有一个 docker-compose yaml 文件，当文件运行时，一切似乎都顺利启动。我可以看到容器正在使用 docker ps 运行。我可以看到它正在侦听正确的端口，但是当我尝试通过浏览器连接时，它拒绝连接。

我的 yaml 文件

version: '3'
services:
  product-search-service:
    build: ./product-search-app
    ports:
      - 8000:5000
  product-shipping-service:
    build: ./product-shipping-app
    ports:
      - 9000:5000
  website-app:
    build: ./web-app
    ports:
      - 127.0.0.1:8080:80
    volumes:
      - ./web-app/public-html:/usr/local/apache2/htdocs/

我正在通过网络浏览器连接到 127.0.0.1:8080

我还想指出，我一直在关注本教程，并且我可以确认所有之前的步骤都已正确完成，因为我现在已经多次这样做了

https://cpit490.gitlab.io/labs/lab-8/

当我尝试连接到 127.0.0.1 时，是否可以启用任何日志记录功能以便更好地了解发生了什么？

我正在使用 docker 工具箱，以防这有什么不同。我没有win10 pro或企业版，所以我不得不使用工具箱

【问题讨论】：

请包含docker run --rm --net container:${cid} nicolaka/netshoot ss -lnt 的输出，其中${cid} 是网站应用容器的容器ID。
嗨@BMitch我不确定我是否正确运行了这个，但这是运行的命令和我收到的输出 $ docker run --rm --net container:b605c0901b9f nicolaka/netshoot ss - lnt 无法在本地 C:\Program Files\Docker Toolbox\docker.exe 找到图像“nicolaka/netshoot:latest”：来自守护进程的错误响应：获取registry-1.docker.io/v2：拨号 tcp：在 10.0 上查找 registry-1.docker.io。 2.3:53: 读取 udp 10.0.2.15:34228->10.0.2.3:53: i/o 超时。请参阅 'C:\Program Files\Docker Toolbox\docker.exe run --help
您有互联网连接吗？表示您的 DNS 服务器找不到 docker hub。如果您处于断开连接的环境中，则需要先通过其他方式提取该图像。
屏幕截图显示尝试连接到端口 8081，但不是 8080...
是的，有互联网连接。我已经运行了一些其他 docker 项目，它们连接得很好。关于港口。 8080、8081、443、80等我都试过了

标签： spring docker docker-compose

【解决方案1】：

所以我已经解决了这个问题。

因为我在 Win10 主页上运行 Docker Toolbox，所以我的 docker 是从拥有自己 IP 地址的 VirtualBox 运行的。要连接到我的 webapp，我需要使用 VB 的 IP 而不是我的本地主机。 Win10 home 没有虚拟机管理程序，所以 localhost 基本上对我来说是被锁定的 :(

归功于Docker Toolbox - Localhost not working

【讨论】：

【解决方案2】：

您似乎没有将容器的端口正确映射到 localhost。更新您的 yaml 文件，如下所示：

version: '3'  
services:      
product-search-service:

          build: ./product-search-app
          ports:
            - 8000:80
            - 8001:443      
product-shipping-service:

          build: ./product-shipping-app
          ports:
            - 9000:80
            - 9001:443      
website-app:

          build: ./web-app
          ports:
            - 8080:80
            - 8081:443
          volumes:
            - ./web-app/public-html:/usr/local/apache2/htdocs/

现在您可以浏览到本地主机：8080 或本地主机：8081

【讨论】：

嘿，谢谢你的回答。不幸的是，它似乎没有用。我尝试从命令提示符发送 curl 请求，但即使这样也拒绝连接。
现在附上。网络选项卡不显示任何信息，只是文档请求
现在还公开网站应用程序（在 dockerfile 中）的端口，例如 EXPOSE 80 EXPOSE 443
刚刚试过这个。结果相同。我在新编辑中包含了 web 应用程序的完整 dockerfile。 dockerfile 是由我在帖子中链接的教程提供的，所以我刚刚添加了你所要求的 Exposes
