This document outlines an agenda for a hands-on workshop on Vagrant for beginners. The agenda includes introductions to Vagrant and VirtualBox, the Vagrant and VirtualBox workflow, getting and configuring base boxes, and provisioning virtual machines using shell scripts. The workshop demonstrates how to use Vagrant to create lightweight reproducible development environments across different operating systems and configuration management tools.

14. $ vagrant init hashicorp/precise32
$ vagrant up
$ vagrant ssh
Getting Up And Running

15. What happened under the hood
$ vagrant init hashicorp/precise32
A Vagrantfile is created
VAGRANTFILE_API_VERSION = ‘2’
vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = ‘hashicorp/precise32’
end

16. What happened under the hood
$ vagrant up
The base box is downloaded and stored locally
in ~/.vagrant.d/boxes
A new VM is created and configured with the base box as
a template
The VM is booted
The box is provisioned

17. Done!
$ vagrant ssh
You have a working VM ready for use

19. Finding base boxes
https://atlas.hashicorp.com/boxes/search

20. Using another base box
$ vagrant box add hashicorp/precise64 & Update Vagrantfile
or
$ vagrant init hashicorp/precise64

21. Vagrantfile after
VAGRANTFILE_API_VERSION = ‘2’
vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = ‘hashicorp/precise64’
end

22. Applying the change
$ vagrant destroy
$ vagrant up
$ vagrant ssh

23. Vagrant introduction

24. Modified VM
VAGRANTFILE_API_VERSION = ‘2’
vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = ‘hashicorp/precise64’
config.vm.provider :virtualbox do |vb|
vb.name = HOST_NAME
vb.customize [‘modifyvm’, :id, ‘--memory’, 256]
end
end

25. Applying the change
$ vagrant reload
or
$ vagrant destroy -f
$ vagrant up

26. Task
Create a VM:
Name - DevOpsTLV
Memory - 1GB
CPUs - 2

27. $ vagrant init user/box # Create Vagrantfile for specified
base box
$ vim/notepad Vagrantfile # Customize your box
$ vagrant up # Create VM if needed and boot
$ vagrant reload # After every change to Vagrantfile
$ vagrant halt # Poweroff
$ vagrant destroy # Clean up!
$ vagrant ssh # log in
$ vagrant status # Status of your VM

29. Shell Provisioning
Add to your Vagrantfile
config.vm.provision 'shell', path: 'provision.sh'
Put the script into the same folder as
Vagrantfile

30. $ vagrant@precise32:~$ ls /vagrant/
provision.sh Vagrantfile
Synced folders

31. Recommended workflow
First do the installation manually (vagrant ssh)
Make sure every command runs without user interaction!
Record every command in the script
If everything works: vagrant destroy -f && vagrant up

32. Task
Write a provision.sh script which:
Install nginx
Starts the nginx service

33. That’s it
(for today)
