Service Providers Perspective

Applications as cost centres

Concerns for disruption of business models

Lack of data control

Fragmentation in data silos

Users Perspective

Personal data on the cloud

OPENi Approach

• An open-source cloud platform that will allow Users to instantiate, deploy and manage their own Cloudlet.

• An API framework that will allow Developers to build applications that integrate dynamically a broader spectrum of cloud-based services and at the same time can access User Cloudlets to store and retrieve content and data.

• A set of value adding services, that will allow Developers to easily access and use the content and data stored in the Cloudlets across several applications and devices.

Key Results

API Framework

• User-centric, «Graph» API based on REST & JSON• Abstracts functionality of Cloud-based Services

into uniquely identified objects• Accompanied by a developers’community-based platform

Cloudlet

Cloudlet

• Each cloudlet is addressable• API Component embedded in Cloudlet• All communication via REST/JSON• Portability, security, privacy, ownership

We started developing

But soon….

We discovered Vagrant..

• What is Vagrant?

• Created by Mitchell Hasimoto

• Provisioning Tools for Dev, Production & Test Environments

• Syntactic sugar around VMs and Containers

• Syntactic sugar around provisioning

• Why use Vagrant?

• Quick

• Easily replicate production on a Dev box

• Easily go production from a Dev box

• Mature, stable, proven

OR

AND

One container to rule them all? Full-stack container vs one container per stack

Step 1: Install Vagrant

• http://www.vagrantup.com/downloads.html

• Mac OSX

• Windows

• Debian/Ubuntu

• CentosOS/Redhat/Fedora

Step 2: Project Setup

$ mkdir vagrant_getting_started

$ cd vagrant_getting_started

$ vagrant init

Step 3: Select a Box

• http://www.vagrantbox.es

• Ubuntu, OpenSuse, OpenBSD, CentOS, Debian..

• Select Provider (VM or Container)

Step 4: Show/Edit Vagrantfile

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

config.vm.box = “precise64“

config.vb.box_url = “http://bit.ly/1gLmNF0”

end

Step 5: Up!

$ vagrant up

Step 6: Connect!

$ vagrant ssh

Success!!

More Commands

• status : status of the machine

• halt : stop machine

• suspend : suspend machine

• reload : restar machine (load new vagrantfile)

• resume : resume suspended machine

• provision : force provisionning machine

• destroy : stop and delete machine

• box : manages boxes

• …

More Providers (native or plugin)

• VMs:

• VirtualBox, KVM, Hyper-V, VMware, libvirt

• Containers:

• lxc, docker

• Services:

• AWS, DigitalOcean, HP Cloud, Joyent, Rackspace, OpenStack, CloudStack, vSphere…

Customize

• config.vm.box* : Box information

• config.vm.network* : Network

• config.ssh* : SSH connection

• config.vm.synced_folder : Share folder

• config.vm.provider* : Custom provider settings

• config.vm.provision* : Provisioning (Puppet, Chef, Docker, Shell…)

Provisioning?

• Automatically install software, alter configuration and more

• Shell Scripts

• File

• Puppet (Standalone & Agent)

• Chef (Solo & Client)

• Ansible

• Salt

• Docker!!!

• Open-Source Container for Dummies

• Create lightweight, portable, self-sufficient container from any app.

• Build once… run anywhere

• Configure once… run anything

• Ecosystems! OS, VM’s, PaaS, IaaS…

• Base: LXC, OpenVZ, systemd-nspawn, libvirt-lxc, libvirt-sandbox, qemu/kvm, Jails, Solaris Zones, chroot (0.9*)

Vagrant and Docker

• BOX = Machine

• Docker = Container (App package inside the Box)

• Functions: Pull, Build, Run

• Allow others provisioning (Shell, puppet, chef)

Docker in Vagrantfile

Vagrant.configure("2") do |config|

v = config.vm

v.box = "precise64"

v.box_url = "http://bit.ly/1gLmNF0"

v.network "forwarded_port", guest: 5000, host: 9292

v.provision "docker", images: [“dg/docker-sample"]

v.provision “docker“ do |d| d.run “dg/docker-sample”, args: "-p 5000:5000“ end

end

Up!

$ vagrant up

Connect!

Success!!
