Vagrant + Dockerbuilding portable environments

David Giordano@3dgiordano

Introduction

• 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

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!!
