کار با Docker بر روی ویندوز - قسمت پنجم - ایجاد Imageهای سفارشی
سلام
چرا نمیتونیم یک image ویندوزی خیلی ساده وبدون وابستگی بسازیم؟ 
مثل چیزی که برای لینوکس امکانش هست
FROM scratch
COPY hello /
CMD ["/hello"]
همین رو برای ویندوز مجبوریم به شکل زیر بنویسیم
FROM mcr.microsoft.com/windows/nanoserver:1809
COPY hello.txt C:
CMD ["cmd", "/C", "type C:\\hello.txt"]
