Vagrant

Vagrant provides reproducible, portable development environments using Virtual Machines (VirtualBox, VMWare, Hyper-V).

When to Use

• Legacy/Full OS Dev: You need to simulate a full Linux Kernel or multi-vm network that Docker cannot easily do.
• Local Testing: Testing Ansible Playbooks locally on a clean VM.
• Windows/Mac: Running Linux VMs on non-Linux hardware with ease.

Quick Start

# Vagrantfile
Vagrant.configure("2") do |config|
  config.vm.box = "hashicorp/bionic64"
  config.vm.network "forwarded_port", guest: 80, host: 8080
