The document provides an overview of Vagrant, an open-source tool designed to create and manage virtualized development environments to address the 'works on my machine' problem. It covers Vagrant's architecture, lifecycle commands, provisioning methods, and the creation of reusable virtual machine boxes using additional tools like Packer. The presentation also discusses using Vagrant in web development scenarios, highlighting its compatibility with various programming languages and frameworks.

Types of ProvisionersTypes of Provisioners
Name Description
file The file provisioner allows you to upload a file or directory from the host
machine to the guest machine.
shell The shell provisioner allows you to upload and execute a script within the
guest machine.
ansible,
ansible_local
The Ansible provisioner allows you to provision the guest using Ansible
playbooks by executing ansible-playbook from the Vagrant host; ansible_local
is executed on the guest machine.
cfengine The CFEngine provisioner allows you to provision the guest using CFEngine.
chef_solo,
chef_zero,
chef_client,
chef_apply
Provision with Chef 'cookbooks' and 'recipes' using a Chef Server. chef_solo
doesn't need a server and is easy to setup.
docker The docker provisioner can automatically install Docker, pull Docker
containers, and configure certain containers to run on boot.
puppet,
puppet_server
The Puppet provisioner, 'puppet' does not require a Puppet Master.
salt The salt Provisioner allows you to provision the guest using Salt states.
