Docker 's Error: libselinux conflicts with fakesystemd
Try running this inside the container you create, before any installation is made:
yum swap -y fakesystemd systemd && yum clean allyum update -y && yum clean all
Or inside a Dockerfile at the begining before the first RUN you have tipped:
RUN yum swap -y fakesystemd systemd && yum clean all \ && yum update -y && yum clean all
Hope was useful!
