A Vagrantfile is createdVAGRANTFILE_API_VERSION = ‘2’

vagrant.configure(VAGRANTFILE_API_VERSION) do |config|config.vm.box = ‘hashicorp/precise32’

end

What happened under the hood

in ~/.vagrant.d/boxes

A new VM is created and configured with the base box as

a template

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_NAMEvb.customize [‘modifyvm’, :id, ‘--memory’, 256]

endend

Applying the change

$ vagrant reload

or

$ vagrant destroy -f

$ vagrant up

Task

Create a VM:

Name - DevOpsTLV

Memory - 1GB

CPUs - 2

$ 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

Agenda

Shell Provisioning

Add to your Vagrantfile

config.vm.provision 'shell', path: 'provision.sh'

Put the script into the same folder as

Vagrantfile

$ vagrant@precise32:~$ ls /vagrant/

provision.sh Vagrantfile

Synced folders

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

Task

Write a provision.sh script which:

Install nginx

Starts the nginx service

That’s it

(for today)
