FROM registry.suse.com/suse/sle15:15.5 ADD https://rpmfind.net/linux/opensuse/distribution/leap/15.5/repo/oss/noarch/python3-Jinja2-2.10.1-3.10.2.noarch.rpm /tmp RUN zypper in -y --no-recommends /tmp/python3-Jinja2-2.10.1-3.10.2.noarch.rpm

ENTRYPOINT [""] CMD ["bash"]

2. Build an image from Dockerfile

$ docker build -t "suse15.5_python3-jinja:v1" .

3. Test with Grype now

$ grype --distro sles:15.5 suse15.5_python3-jinja:v1
