Experiment: Running IaaS Cloud Inside Container

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 :

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 :

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
Checking AppArmor  SKIP will try to modify
Checking for present ssh key  SKIP
Checking (iptables|netfilter)-persistent are installed  SKIP will try to install

### Main deployment steps:
Install OpenNebula frontend version 5.12
Configure bridge minionebr with IP 172.16.100.1/24
Enable NAT over eth0
Modify AppArmor
Install OpenNebula KVM node
Export appliance and update VM template
Install  augeas-tools apt-transport-https iptables-persistent netfilter-persistent
