With Red Hat's UBI Micro:
microcontainer=$(buildah from registry.access.redhat.com/ubi8/ubi-micro)
micromount=$(buildah mount $microcontainer)
yum install \
--installroot $micromount \
--releasever 8 \
--setopt install_weak_deps=false \
--nodocs -y \

great. Now I have to install and learn another tool when having yum inside the container will just work?
