Vagrant enables users to create and configure lightweight, reproducible, and portable development environments.
Vagrant is like a DevOps time machine that spins up a fully-configured virtual machine using one file and one command.
To use Vagrant, initialize the project with a Vagrantfile and configure it, specifying the base image, network settings, synced folders, and provider-specific settings like VM name, memory, and CPUs.
Vagrant is a useful tool for building isolated environments, creating reproducible VMs for testing installations, safely testing Ansible playbooks, and setting up disposable Proof-of-Concepts (PoCs).
