Ubuntu

Redhat use its own registry: Redhat container catalog.

Get base Image from the RedHat Registry with docker: 

# Minimu Size
# https://access.redhat.com/containers/?tab=overview&platform=docker#/registry.access.redhat.com/rhel7-atomic
docker pull registry.access.redhat.com/rhel7-atomic
# Full
# https://access.redhat.com/containers/?tab=overview&platform=docker#/registry.access.redhat.com/rhel7.5
docker pull registry.access.redhat.com/rhel7.5

Then: Example starting Redhat with mounting the actual current directory to /wd with the cmder console 

SOURCE_MOUNT_POINT=$(cygpath -u $(readlink -f .))
docker run  \
    --mount type=bind,source=/$SOURCE_MOUNT_POINT,target=/wd \
    -rm \
    -it \
    registry.access.redhat.com/rhel7 \
    bash

yum install wget
yum install vim
