This guides ends with setting up ssh keys. Most of the commands could easily be done on all systems once the ssh key is setup. Ie. if a user adds a file like:

cat <<EOF > ~/bin/runall
#!/bin/bash
# Run command on all hosts
HOSTS="host1 host2 host3"
for host in $HOSTS
do
  echo Running command on host $host
  ssh $host "$@"
done
EOF
chmod 775 ~/bin/runall

This would allow the user to type "runall subscription-manager register" and "runall yum instal docker"  etc.
