build a REMnux system from scratch, use the Ubuntu 14.04 64-bit minimal ISO
a virtual machine, allocate at least 1GB of RAM and 25GB disk
the user named “remnux” with the password “malware”

#command to install the REMnux distro
wget --quiet -O - https://remnux.org/get-remnux.sh | sudo bash

Isolate REMnux within your lab by configuring the virtual appliance to use a “host only” network. 
#After switching networks, run the renew-dhcp command in REMnux to refresh its network settings.

Fedora (Single Node)
The Kubernetes package provides a few services: kube-apiserver, kube-scheduler, kube-controller-manager, kubelet, kube-proxy. 
These services are managed by systemd and the configuration resides in a central location: /etc/kubernetes
We will break the services up between the hosts.
https://kubernetes.io/docs/getting-started-guides/fedora/fedora_manual_config/

#fed-master, the Kubernetes master
#This host will run the kube-apiserver, kube-controller-manager, and kube-scheduler
#the master will also run etcd (not needed if etcd runs on a different host but this guide assumes that etcd and Kubernetes master run on the same host)
#fed-node will be the node and run kubelet, proxy and docker.

Create first a CentOS virtualbox VM then convert to a vagrant box

#Create a new virtual machine with the following settings:
    Name: centos74minimal
    Type: Linux
    Version: Redhat 64
    Memory Size: 1024MB (to taste)
    New Virtual Disk: [Type: VMDK, Size: 40 GB]
		Disable floppy
    Disable audio
