Learn VAGRANTFILE with Real Code Examples

Host Machine - runs Vagrant CLI

Guest VM - provisioned virtual environment

Vagrantfile - declarative configuration

Provider - virtualization backend (VirtualBox, Docker, VMware)

Provisioner - configuration management or scripts executed inside VM

Vagrantfile -> vagrant CLI -> Provider -> VM created -> Provisioners executed -> Environment ready
