Is there any way to copy multiple directories in one command, to reduce the number of layers? E.g., instead of:
COPY dirone ./dirone
COPY dirtwo ./dirtwo
COPY dirthree ./dirthree
I want to do:
COPY dirone/ dirtwo/ dirthree/ ./
However, this copies the contents of the directories... but I want to copy the directories themselves.
That's the documented behavior of the copy command:
If
<src>
is a directory, the entire contents of the directory are copied, including filesystem metadata.Note: The directory itself is not copied, just its contents.
Best workaround I can suggest is to change your directory layout in your build folder, move the three folders under one parent folder and add the parent.
