What is vagrant and why to use it?


Asked by Bailey Stark on Dec 14, 2021 FAQ



A vagrant is a tool for building and managing virtual machine environments in a single workflow. Vagrant provides a simple and easy to use command-line client for managing these environments, focus on automation, and an interpreter for the text-based definitions of what each environment looks like, called Vagrantfiles.
Also Know,
You can use vagrant up and vagrant ssh to launch and log into the virtual machine, then create a test document in the /vagrant directory. Use the exit command to close the SSH session, then use ls to list the contents of your vagrant-test directory.
Subsequently, Vagrant automatically synchronizes content that is in your project directory with a special directory in the guest (virtual) system. The project directory is the one you created earlier, /vagrant-test. It’s also the same one that holds the Vagrantfile. When you log into the virtual machine, by default it starts in the /home/vagrant/ directory.
Besides,
Vagrant Cloud serves a public, searchable index of Vagrant boxes. It's easy to find boxes you can use with Vagrant that contain the technologies you need for a Vagrant environment. You don't need a Vagrant Cloud account to use public boxes.
Furthermore,
When you run any vagrant command, Vagrant climbs up the directory tree looking for the first Vagrantfile it can find, starting first in the current directory. So if you run vagrant in /home/mitchellh/projects/foo , it will search the following paths in order for a Vagrantfile, until it finds one:
