Is is possible to chain the COPY commands together like what can be done with the RUN command?
Example of chaining run command:
RUN echo "root:user_2017" | chpasswd && \
groupadd -g 1000 user && \
useradd -u 1000 -m -s /bin/bash user && \
passwd -d user
Would something like what is shown below prevent the introduction of multiple intermediate images if I had to perform many copies from the host to the image? I know what is shown below won't work because each line needs to be a separate command when the && is used to tie multiple lines together.
COPY ./folder1A/* /home/user/folder1B/ && \
./folder2A/* /home/user/folder2B/ && \
./folder3A/* /home/user/folder3B/ && \
./folder4A/* /home/user/folder4B/ && \
