In this experiment, I am trying to build an IaaS inside container.Better to name -"container cloud".
If you don't know about different types of clouds, please visit my post :
Creating Your Cloud Infrastructure like Google cloud and Digital Ocean from Scratch: Part -1

Different types of Clouds:
SAAS: SOFTWARE AS A SERVICE
PAAS: PLATFORM AS A SERVICE
IAAS: INFRASTRUCTURE AS A SERVICE
Common Examples of SaaS, PaaS, & IaaS:
SaaS:Google Apps, Dropbox, Salesforce, Cisco WebEx, Concur, GoToMeeting
PaaS:AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com, Google App Engine, Apache Stratos, OpenShift
IaaS:DigitalOcean, Linode, Rackspace, Amazon Web Services (AWS), Cisco Metapod, Microsoft Azure, Google Compute Engine (GCE)
There are different types of containers and their pros & cons. you can get some details here :
New Type of Docker : Rootless + Safer : for every Docker user.

I am choosing LXC!!! why?
- nearest like VM , its VE.
- Allows iptables -easy like VM. For IaaS , I am choosing Opennebula. My these two articles can help you to understand more about opennebula:

STEP-1: Download and run lxd. New to containers? or LXD? learn here:

STEP-2: Download and run Opennebula.(https://github.com/OpenNebula/minione)
c1 is my container.
If you have kvm enabled host then try kvm / firegate else lxc minions script.
root@vmi307975:~#lxc launch ubuntu:18.04 c1 -c security.privileged=true -c security.nesting=true
root@vmi307975:~# lxc exec c1 bash
root@c1:~# wget 'https://github.com/OpenNebula/minione/releases/latest/download/minione'
root@c1:~# sudo bash minione --force
### Checks & detection
Checking cpu virtualization capabilities SKIP QEMU will be used
Checking augeas is installed SKIP will try to install
Checking free disk space IGNORE
Checking apt-transport-https is installed SKIP will try to install
