ADD Dockerfile command does not unpack tarballs #298
Open
Description
Describe the bug
ADD tarball.tar.gz / is supposed to unpack the said tarball into the root. Instead, it just copies it into it.
To Reproduce
The specific Dockerfile I ran into this at:
FROM scratch
ENV LANG=C.UTF-8
ENV LC_ALL=C.UTF-8
ARG DEBIAN_FRONTEND=noninteractive
ARG OSPACK=debian.tar.gz
ADD ${OSPACK} /
RUN apt-get update
Here, debian.tar.gz is a minimal Debian rootfs tarball.
Expected behavior
The tarball is unpacked, so that I can run commands using its contents.
Instead, I’m getting:
info * Step 6/7 (modifyfs) : ADD debian.tar.gz / (465a0d0c)
info * Execute ADD debian.tar.gz / (465a0d0c) took 91.261753ms
info * Not committing step ADD debian.tar.gz / (465a0d0c)
info * Step 6/7 (modifyfs) : RUN apt-get update (d6692f4c)
