You can make sure you have the same libraries and dependencies installed, same processes installed, same operating system and version, and many other details without having to sacrifice the way your local machine is set up, and without the lag or cost of creating an external development environment and connecting to it. While at its core, Vagrant provides a rather simple function, it may be useful to a wide range of people working on different kinds of tasks.įor developers, Vagrant makes it easy to create a local environment which mimics the environment upon which your code will eventually be deployed. It also means that rather than sharing a whole virtual machine image, which could be many gigabytes, every time a change is made to the configuration, a simple text file weighing at just a few kilobytes can be shared instead. While many virtual machine hypervisors provide their own command-line interface, and technically the provisioning of virtual machines through these programs can be done directly or through shell scripts, the advantage Vagrant provides by adding an additional layer is simplicity, interoperability across multiple systems, and a more consistent approach which could theoretically be used with any virtual environment running on top of any other system.īy providing a common text-based format to work with virtual machines, your environment can be defined in code, making it easy to back up, modify, share, and manage with revision control. Vagrant is open source, which means that anyone can download it, modify it, and share it freely. Vagrant provides a simple and easy to use command-line client for managing these environments, and an interpreter for the text-based definitions of what each environment looks like, called Vagrantfiles.
In a nutshell, Vagrant is a tool for working with virtual environments, and in most circumstances, this means working with virtual machines.
