Windows的Docker上的nodemcu构建失败

Question

构建过程因“权限被拒绝”而终止。

背景

拉并捕获marcelstoer / nodemcu-build的最新图像。并运行构建过程。它在Powershell下运行。

PS> $inv=${Get-Location}.Path
PS> docker run --rm -it -v ${inv}:/opt/nodemcu-firmware marcelstoer/nodemcu-build build
esp-open-sdk/

权限问题？

我猜想Window和Docker之间的权限问题。检查对Ubuntu映像的权限。

PS> docker run --rm -it -v ${inv}:/opt/nodemcu-firmware ubuntu
root@3c6ec540bf04:/# ls /opt/nodemcu-firmware/
CONTRIBUTING.md  LICENSE  Makefile  README.md  app  bin  docs  ld  local  lua_examples  lua_modules  mkdocs.yml  rtd-requirements.txt  sdk-overrides  tools

ls: cannot access 'aa': No such file or directory
root@3c6ec540bf04:/opt/nodemcu-firmware#`

看起来不错。 nodemcu映像有什么问题？

Env。

Windows 10 Pro 10.0.17134 N/A Build 17134

解决方法

PS > docker run --rm -it -v ${inv}:/opt2/nodemcu-firmware marcelstoer/nodemcu-build bash

构建完成。我想这是Windows上Docker上的权限处理问题。
