Hello,
i use OpenSuSE 42.1 (64bit) with Docker: 1.9.1.
Like to build my own Image from OpenSuSE Leap 42.1
mounted ISO to /media

My Dockerfile:

FROM scratch
ADD //media/suse/x86_64/bash-4.2-76.4.x86_64.rpm /bash-4.2-76.4.x86_64.rpm
RUN rpm -ivh /bash-4.2-76.4.x86_64.rpm

dockeradmin@linux-ra62:~> ls -la /media/suse/x86_64/bash-4.2-76.4.x86_64.rpm

What did i wrong ?

Thanks

You can’t ADD or COPY things from outside the current directory. Outside Docker copy whatever artifacts to the current directory or a subdirectory first.

If you do get here, this won’t work: your FROM scratch container won’t have a /usr/bin/rpm to run, or anything else at all: it’s a totally blank filesystem. If you’re starting FROM scratch then your basic options are to ADD a complete Linux distribution filesystem tar file, COPY in an all-in-one statically linked binary like Busybox, or COPY in a statically linked application binary.

It’s almost always easier to start from one of the prebuilt Linux distribution images, e.g. FROM ubuntu:16.04. (There’s absolutely no requirement that containers and the host run the same distribution.)
