I have been using Linux daily for several years but my go to desktop machine has always been either macOS or Windows. However, when I moved into the Cloud Native role I am in now I took the plunge to make sure that my laptop was fully Linux based and my daily driver, whilst I still needed Windows for work-based applications and a lot of my audio and video gear does not run on Linux I was forcing myself to run a Linux desktop full time to get a better grasp of a lot of the things we are going to touch on over the next 7 days.

I am not suggesting you do the same as me by any stretch as there are easier options and less destructive but I will say taking that full-time step forces you to learn faster how to make things work on Linux.

For the majority of these 7 days, I am going to deploy a Virtual Machine in Virtual Box on my Windows machine. I am also going to deploy a desktop version of a Linux distribution, whereas a lot of the Linux servers you will be administering will likely be servers that come with no GUI and everything is shell-based. However, as I said at the start a lot of the tools that we covered throughout this whole 90 days started on Linux I would also strongly encourage you to dive into running that Linux Desktop for that learning experience as well.

## Introducing HashiCorp Vagrant ## Introducing HashiCorp Vagrant
Vagrant is a CLI utility that manages the lifecycle of your virtual machines. We can use vagrant to spin up and down virtual machines across many different platforms including vSphere, Hyper-v, Virtual Box and also Docker. It does have other providers but we will stick with that we are using Virtual Box here so we are good to go. Vagrant is a CLI utility that manages the lifecycle of your virtual machines.

The first thing we need to do is get Vagrant installed on our machine, when you go to the downloads page you will see all the operating systems listed for your choice. [HashiCorp Vagrant](https://www.vagrantup.com/downloads) I am using Windows so I grabbed the binary for my system and went ahead and installed this to my system.

Next up we also need to get [Virtual Box](https://www.virtualbox.org/wiki/Downloads) installed.

Both installations are pretty straightforward. If you have issues both have great communities around them also feel free to reach out and I can try to assist also.

## Our first VAGRANTFILE ## Our first VAGRANTFILE
The VAGRANTFILE describes the type of machine we want to deploy. It also defines how we want the configuration and provisioning of this machine need to look. The VAGRANTFILE describes the type of machine we want to deploy. It also defines the configuration and provisioning for this machine.
When it comes to saving these and organizing your VAGRANTFILEs I tend to put them in their folders in my workspace. You can see below how this looks on my system. Hopefully following this you will play around with Vagrant and see the ease of spinning up different systems, it is also great for that rabbit hole known as distro hopping for Linux Desktops.

This is a very simple VAGRANTFILE overall we are saying we want a specific "box" a box being possibly either a public image or private build of the system you are looking for. You can find a long list of "boxes" publicly available here in the [public catalogue of Vagrant boxes](https://app.vagrantup.com/boxes/search) This is a very simple VAGRANTFILE overall.

Next line we are saying we want to use a specific provider in this case it is `VirtualBox` and then we want to define our machine's memory to `8GB and our number of CPUs to `4`. My experience also tells me that you may want to also add the following line if you experience display issues. This will set the video memory to what you want, I would ramp this right up to `128MB but depends on your system.

We are now ready to get our first machine up and running, in your workstations terminal. In my case I am using PowerShell on my Windows machine, navigate to your projects folder and where you will find your VAGRANTFILE. Once there you can type the command `vagrant up` and if everything is correct then you will see something like the below.

Another thing to add here is that the network will be set to `NAT` on your virtual machine, at this stage we don't need to know about NAT and I plan to have a whole session talking about it in the next section about Networking. But know that it is the easy button when it comes to getting a machine on your home network, it is also the default networking mode on Virtual Box. You can find out more in the [Virtual Box documentation](https://www.virtualbox.org/manual/ch06.html#network_nat) Another thing to add here is that the network will be set to `NAT` on your virtual machine.
