Vagrant, what is it?

Question

Vagrant

I just can’t figure out why vagrant is needed.
Can you explain in simple terms what it is and why it is needed ?!
And what is the connection with virtual boxing?

Answer 1

a system for automatically creating virtual machines with the necessary parameters (axis / its specific version, a set of necessary software).
there is no connection with virtualbox as such, although vagrant can also use it to create virtual machines.

Answer 2

Vagrant is a software layer that drives virtualbox (any other virtual machine system).
In a file, you describe the configuration of popular assemblies that are stored on a certain hub + you can assemble and save your own, plus install (again in a file, programmatically) the necessary modules / software. The very fact that in addition to virtualbox there will be another system is also the necessary functionality, that is, the same configuration, but different drivers.
Thanks to this, you can deploy an exact copy of the OS with exact versions of software with the desired configuration with one command and share it, for example, between team members and always develop in the same environment, which can be an emulation of a combat environment.
