## Create a VM with Terraform & Variables
In this session we are going to be creating a VM or two VMs using terraform inside VirtualBox. This is not the normal, VirtualBox is a workstation virtualisation option and really this would not be a use case for Terraform but I am currently 36,000ft in the air and as much as I have deployed public cloud resources this high in the clouds it is much faster to do this locally on my laptop.

Purely demo purpose but the concept is the same we are going to have our desired state configuration code and then we are going to run that against the virtualbox provider. In the past we have used vagrant here and I covered off the differences between vagrant and terraform at the beginning of the section.

### Create a virtual machine in VirtualBox
The first thing we are going to do is create a new folder called virtualbox, we can then create a virtualbox.tf file and this is going to be where we define our resources. The code below which can be found in the VirtualBox folder as virtualbox.tf this is going to create 2 VMs in Virtualbox.

Now that we have our code defined we can now perform the `terraform init` on our folder to download the provider for virtualbox.

Obviously you will also need to have virtualbox installed on your system as well. We can then next run `terraform plan` to see what our code will create for us. Followed by `terraform apply` the below image shows your completed process.

### Change configuration
Lets add another node to our deployment. We can simply change the count line to show our newly desired number of nodes. When we run our `terraform apply` it will look something like below.

Once complete in virtualbox you can see we now have 3 nodes up and running.
