This document provides an introduction and overview of using Vagrant to manage virtual machines. It begins with a brief explanation of what Vagrant is and its basic features. It then demonstrates simple commands to install Vagrant, add a base box, initialize a Vagrantfile configuration, and boot a virtual machine. The document progresses to more advanced Vagrantfile configuration topics like specifying base boxes, network configuration, shared folders, and defining multiple virtual machines. It also introduces using Puppet configuration management with Vagrant to provision virtual machines in a repeatable way.

6. Simple Command Line
$ gem install vagrant
$ vagrant box add base <box url>
$ vagrant init
$ vagrant up

7. Step 1 :: Installation with Ruby Gem
$ gem install vagrant

8. Step 2 :: Add Base Box
$ vagrant box add base
http://files.vagrantup.com/precise32.box
…….
[vagrant] Downloading withVagrant::Downloaders::File...
[vagrant] Copying box to temporary location...
[vagrant] Extracting box...
[vagrant]Verifying box...
[vagrant] Cleaning up downloaded box...

9. Step 2.1 :: Where is my box ?
o http://www.vagrantbox.es/

10. Step 3 :: Configuration
$ vagrant init
…..
A `Vagrantfile` has been placed in this directory.You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in theVagrantfile as well as documentation on
`vagrantup.com` for more information on usingVagrant.

11. Vagrantfile
Vagrant::Config.run do |config|
config.vm.box = "base“
end

12. Step 4 :: Boot
$ vagrant up
….
[default] Importing base box 'base'...
[default] Matching MAC address for NAT networking...
[default] Clearing any previously set forwarded ports...
[default] Fixed port collision for 22 => 2222. Now on port 2200.
[default] Forwarding ports...
[default] -- 22 => 2200 (adapter 1)
[default] Creating shared folders metadata...
[default] Clearing any previously set network interfaces...
[default] BootingVM...
[default] Waiting forVM to boot.This can take a few minutes.

13. Ready to SSH
User=vagrant
Password=vagrant

14. Optional Command
$ vagrant status
$ vagrant halt
$ vagrant destroy
$ vagrant reload
$ vagrant provision
$ vagrant suspend
$ vagrant resume

17. Working with Vagrantfile
o Specified base box
o Network Configuration
o Sharing Folder
o MultipleVM

18. Specified Base Box
Vagrant::Config.run do |config|
config.vm.box = "lucid32“
config.vm.box_url =
"http://files.vagrantup.com/lucid32.box"
config.vm.box_url = "c:demo-geekylucid32.box"
end

19. Network Configuration
Vagrant::Config.run do |config|
config.vm.network :hostonly, "33.33.33.10"
end

20. Sharing Folder
Vagrant::Config.run do |config|
config.vm.share_folder "foo", "/guest/path", "/host/path"
end
Path on VM Path on Local

21. Sharing Folder
Vagrant::Config.run do |config|
config.vm.share_folder "work",
"/var/www",
"./webapp”
end

22. Multiple VM in Stack
o Web Server
o Application Server
o Database Server
o Caching Server
o Messaging Server

23. Web Server and DB Server
Vagrant::Config.run do |config|
config.vm.define :web do |web_config|
web_config.vm.host_name = "web01.internal"
web_config.vm.network :hostonly, "192.168.0.100"
end
config.vm.define :db do |db_config|
db_config.vm.host_name = "db01.internal"
db_config.vm.network :hostonly, "192.168.0.101"
end
end

24. DEMO MORE
o Flexible configuration
o # of Server
o Hostname
o Manage IP

25. DEMO MORE
o Web Server
o web-01.vagrant.internal 33.33.33.11
o web-02.vagrant.internal 33.33.33.12
o DB Server
o db-01.vagrant.internal 33.33.33.21

26. Servers
nodes = {
'web' => [2, 10],
'db' => [1, 20],
}

27. Create Servers
nodes.each do |prefix, (count, ip_start)|
count.times do |i|
hostname = "%s-%02d" % [prefix, (i+1)]
config.vm.define "#{hostname}" do |box|
box.vm.host_name = "#{hostname}.vagrant.internal"
box.vm.network :hostonly, "33.33.33.#{ip_start+i}“
end
end
