this will install a bunch of ready to run - pre configured maschines - incl. ip configuration on your host

for rhel based maschines:

# get virtualbox reo and save it under /etc/yum.repos.d
> wget

# install kernel header and build-tools using EPEL
> dnf --enablerepo=epel install dkms
> dnf install kernel-devel-$(uname -r) kernel-headers gcc make perl

# install vbox headless
> dnf install --setopt=install_weak_deps=False VirtualBox-6.1

# test if installation was successfull
> VBoxManage --version

# enable vbox service
> systemctl enable vboxdrv.service

# add user to vbox group
> usermod -a -G vboxusers vmadmin

# install vagrant
> dnf install yum-utils 
> yum-config-manager \
> dnf install vagrant

# install git
> dnf install git-core

# clone mmumshad for of "kubernetes the hard way"
> git clone
> cd kubernetes-the-hard-way/vagrant

# start building maschines - takes about 10 minutes
> vagrant up --provider=virtualbox

# check vagrant status
> vagrant status
  Current machine states:
  master-1                  running (virtualbox)
  master-2                  running (virtualbox)
  loadbalancer              running (virtualbox)
  worker-1                  running (virtualbox)
  worker-2                  running (virtualbox)

# test ssh login using dn
> vagrant ssh worker-1

# to manage things like scp - append maschines to ssh config  
> vagrant ssh-config >> ~/.ssh/config
> chmod 644 ~/.ssh/config
