Puppet is automation software that helps system administrators manage infrastructure by automating provisioning, configuration, and other repetitive tasks. It ensures consistency and stability. Puppet consists of a Puppet Master and Puppet Agents. Vagrant provides a way to easily create and configure virtual development environments using configuration files and automation (e.g. Puppet). It uses Oracle VirtualBox and allows specifying and provisioning resources. Benefits include consistent environments for development, testing, and teams.

Puppet Adding a Resources
What does it look like:
$ puppet resource user dave ensure=present shell=”/bin/zsh”
home=”/home/dave” managehome=true
Would output:
Notice: /User[dave]/ensure: created
User { 'dave':
Ensure => present,
uid => '507',
gid => 'admin',
shell => '/bin/zsh',
home => '/home/dave',
managehome => true,

Puppet Manifest Classes
The Puppet manifests can become complex.
Class ntp {
package { 'ntp':
ensure => installed,
}
service { 'ntp':
name => 'ntpd',
ensure => running,
enable => true,
subscribe => File['ntp.conf'],
}

Puppet and Vagrant in Development Puppet Resources Puppet defines resources in a array'ish language User { 'dave': Ensure => present, uid => '507', gid => 'admin', shell => '/bin/zsh', home => '/home/dave', managehome => true, } We can see the parts of the structure Type = User Title = Dave Attributes Values

- 16. Puppet and Vagrant in Development Vagrant Virtualized development made easy Lowers setup time Eliminates “works on my machine” excuse Uses Oracle VirtualBox Can use Puppet or Chef FREE and open source
- 17. Puppet and Vagrant in Development Vagrant setup items needed for this example Get VirtualBox from Oracle's download page Install Ruby Required by Vagrant, Chef and/or Puppet. Install Vagrant Talks to VirtualBox and builds virtual machine based on a “base box”. Decide on whether to use Chef or Puppet. Enables setup and configuration of advanced services you may need in your environment.
- 18. Puppet and Vagrant in Development Vagrant Basic How To Create a directory and change to the new directory via command line. Execute three simple commands: $ vagrant box add lucid32 http://files.vagrantup.com/lucid32.box $ vagrant init lucid32 $ vagrant up We now have a working Ubuntu (Lucid Lynx 32 bit) linux server running. However it is very “bare bones”. List installed Boxes $ vagrant box list
- 19. Puppet and Vagrant in Development Benefits of Using Vagrant Solo Developers Maintain consistency across multiple projects. Run multiple environments on a single home machine. (Dev., Test, Staging) Easily tear down and rebuild Teams Identical development environments. Consistent and portable. Companies Easier onboarding of new talent. Build development environment once and distribute to teams.
- 20. Puppet and Vagrant in Development Vagrant Configuration Vagrantfile Simply Ruby code which typically contains a Vagrant configuration block. First thing loaded by Vagrant. Basic file created when 'init' is called from within a directory. Add more options for more configuration.
- 21. Puppet and Vagrant in Development Vagrant Base Box Many base boxes available over the Internet, or you can create your own. Creation convention should be followed A base box must be added via local file or HTTP $ vagrant box add {name} {location to pull from} Or you can remove current base boxes $ vagrant box remove {name} Base box is defined in the Vagrantfile Vagrant::Config.run do |config| config.vm.box = “lucid32” end
- 22. Puppet and Vagrant in Development Testing/Running To launch the bootup/provision we simply tell Vagrant “up”. $ vagrant up Or if you “suspended” to shut down last time you would use “resume”. To shut down we can either “suspend” to save the current state of the machine (does not return disk space, about 1GB), “destroy” everything (requires re-provision), or “halt” which is a graceful shutdown. $ vagrant destroy $ vagrant halt
- 23. Puppet and Vagrant in Development SSH Vagrant makes SSH easy to the virtual machine from within the project directory. $ vagrant ssh Project files are available at '/vagrant' by default, but can be changed. The VM has both read and write access to the shared folder. To gain root (su) access the password is 'vagrant'
- 24. Puppet and Vagrant in Development Provisioning Using Chef or Puppet we can create a manifest to alter the VM. Install apps Edit config files Many tasks needed to go from Base Box to desired environment. Manifests (or recipe for Chef) Manifests sub-directory within project. Default.pp is the default file loaded.
- 25. Puppet and Vagrant in Development Port Forwarding By default your host machine should be able to access the virtual machine by IP address. However, we need to activate port forwarding for services. For HTTP: Vagrant::Config.run do |config| # Forward guest port 80 to host port 4567 config.vm.forward_port 80, 4567 end Then we simply reload Vagrant. $ vagrant reload
- 26. Puppet and Vagrant in Development Packaging Start with a Base Box Customize it as needed, unless relying solely on provisioning with Chef or Puppet. Run command to package $ vagrant package –vagrantfile Vagrantfile.pkg Creates 'package.box' in same directory. Distribute via raw file or via HTTP, for others. Other users can now use: $ vagrant box add my_box /path/to/the/package.box $ vagrant init my_box $ vagrant up
- 27. Puppet and Vagrant in Development Advanced Capabilities of Vagrant Many advanced topics available under Documentation on the Vagrant site. Modules within Manifests to encapsulate Puppet files. Create your own Base Boxes Multi-VM Environment Plugins NFS Shared Folders
