The document provides an overview of Vagrant and Puppet as tools for managing virtual machines and server provisioning. Vagrant streamlines the setup and management of development environments, while Puppet is a configuration management tool that uses manifest files to define system states. Together, they help automate and standardize software deployment and server preparation.

1. Provisioning Vagrant VM using Puppet
Arpit Aggarwal

2. What is Vagrant
● An open source tool written by Mitchell
Hashimoto.
● Wrapper around a variety of VM providers
like VirtualBox, VMware.
● Provides a single command that uniformly
creates, provisions, destroys and connects
to machines.

3. Why Vagrant
● Lowers environmental setup time.
● Increases development/production parity.
● Makes the “works on machine” excuse a
relic of the past.

4. Vagrant Lifecycle
● Vagrant init
● Vagrant up
● Vagrant suspend/halt/destroy

5. What is Provisioning
● Actions to prepare a server with
appropriate systems, data and software.
● Setting up a server for use in the network.

6. Vagrant Provisioners
● Automatically installs softwares, copy data on a
machine.
● Alter configuration of a machine.
● Offers multiple options for provisioning the machine:
– Shell scripts.
– Puppet
– Chef
– Ansible
– Salt.

7. Vagrant Shell Provisioning
● Allows us to upload and execute a script
within the guest machine.
● Shell provisioner options:
– Inline
– Path

8. When Provisioning Happens
● On running
– vagrant up
– vagrant provision
– vagrant reload --provision

9. What is Puppet
● An open-source configuration management
tool written by Luke Kanies.
● Has its own declarative language which
describe system configuration.
●
Programs are called “manifests” and
use the “.pp” file extension.

10. Why Puppet
● Avoid writing in-house scripts.
● Ease the work of Sysadmin.

11. How Puppet Works
● Puppet configures systems in two main
stages:
– Compile a catalog
– Apply the catalog

12. What is a Catalog?
● Document that describes the desired
system state.
● Lists all resources that need to be
managed, as well as any dependencies
between those resources.

13. Catalog Compilation And Execution
● Retrieve the Node Object
● Set Variables from the Node Object
● Evaluate the Main Manifest
● Load and Evaluate Classes from Modules
● Evaluate Classes from the Node Object
