从jar文件中启动postgres docker失败。

问题描述 投票：0回答：1

我有一个java应用，在本地工作正常，但打包成jar文件时却失败了。

应用程序执行以下步骤

  • 应用程序使用ProcessBuilder启动一个docker。容器处理一些文件
  • 应用程序等待该容器关闭并继续运行
  • 应用程序在后台启动第二个postgresql容器，并使用Process Builder将一个文件夹挂载到它上面。
  • 为了安全起见，应用程序等待5秒。
  • 应用程序做了一些逻辑并关闭了一切。

当我在IDE(InteliJ)里面运行App时，它工作得很好，但是当我尝试使用jar文件运行它时，我得到了这个错误信息

我意识到这是一个奇怪的场景，为什么你要从一个jar文件里面发送docker运行命令。但我没有其他选择。

有人遇到过这种类型的问题吗，任何信息都将被感激。谢谢你的帮助

与数据库的连接是如何配置的？

可能发生的情况是，你的数据库在容器内部无法访问。

在docker-compose文档中查找extra_host，你也许可以添加类似的内容。

extra_hosts:
      - "db_host:<your local ip, dont use 127.0.0.1 or localhost>"

然后在spring boot appconfigure你的spring配置中，将数据库主机指向db_host，而不是127.0.0.1或其他任何东西。
