無法使用Docker窗口更改捲上文件/文件夾的權限

Question

我試圖使用Docker窗口更改捲上文件/文件夾的權限。但是，這些權限並沒有被意外更改。

環境： 主持人：視窗10 Pro的 多克爾版本17.09.0策，建立afdb6d4

步驟重現：

1. 構建圖像與下面的Dockerfile。
2. 使用卷運行容器。
3. 更改文件/文件夾的權限。

Dockerfile：

FROM microsoft/windowsservercore 
CMD [ "powershell" ] 

輸出：

D:\data\docker\sample>docker build -t sample . 
Sending build context to Docker daemon 1.272GB 
Step 1/2 : FROM microsoft/windowsservercore

我發現了一個文件，該文件說，文件/文件夾的捲上的權限不能在Linux上的容器改變。但是我找不到有關Windows容器的文檔。 Windows容器是否支持Windows容器上卷上文件/文件夾的權限更改？

從你提到的鏈接看來，docker for windows不支持更改文件權限。

泊塢的Windows currrently實現了基於 微軟SMB協議，該協議不支持細粒度的文件模式在這些權限 控制主機安裝卷。
