docker - 在 Windows 容器中运行 erlang 时出错

Question

我正在尝试在 Windows 容器中启动并运行 RabbitMQ，但运气不佳。我已将 RabbitMQ 和 Erlang 的安装目录复制到容器中，但是当我尝试运行 erl.exe 时，我被告知 beam.smp.dll 无法运行待加载。

PS C:\Program Files\erl8.2\bin> .\erl.exe
Unable to load emulator DLL
(C:\Program Files\erl8.2\erts-8.2\bin\beam.smp.dll)

在主机上的同一安装目录上运行相同的命令效果很好。我已检查该文件是否存在并且校验和是否匹配。我敢打赌，容器加载文件的方式和主机加载文件的方式存在一些细微的差异。我只是不知道从哪里开始寻找。

这是我的 Dockerfile，它可以工作。我可以连接到 RabbitMQ，日志显示它正在正确运行，并且我可以使用容器的 IP/主机名从我的主机使用 guest / guest 登录来登录管理 UI。
