how to use virtualbox for shell scripting

It also makes it easy to create disposable environments to experiment with different technologies. DevOps teams can use Vagrant to spin up multiple VMs running different Linux distributions to test configuration management in different systems. Then, they can be distribute it amongst them, so that everyone can work in the same environment of their OS. Engineers can define a Vagrantfile that installs all the programming language tools and databases for their work. These features are useful in modern teams. Now anyone can recreate the same environment with a few short commands. Once you have everything in the Vagrantfile, you’re ready to go. Then, you use the various provisioners to set everything up. Essentially, this is where you decide the operating system. This may be a VirtualBox image or an AMI (Amazon Machine Image) on AWS. The Vagrantfile defines the “box”, VM customizations (like memory and networking settings), and which provisioners to run. Naturally you can use simple shell scripts to automatically install and configure software as well. Vagrant includes support for configuration management tools like Chef or Ansible. Machines are provisioned on top of VirtualBox, VMWare, AWS, or any other provider. Vagrant makes it easy to create reproducible virtualised environments. Let’s unpack this a bit and discuss what Vagrant is, how it works, and who it’s for. This quote comes straight from the Vagrant website. With an easy-to-use workflow and focus on automation, Vagrant lowers development environment setup time, increases production parity, and makes the “works on my machine” excuse a relic of the past. Vagrant is a tool for building and managing virtual machine environments in a single workflow. We’ll cover how Vagrant works and we’ll show some example use cases. By the end of this tutorial, you’ll be ready to start using Vagrant. Vagrant can be especially useful for cross-platform automated tests.

It’s primarily designed to standardize environments across platforms. It accomplishes this by leveraging virtual machines with VirtualBox, VMWare, or cloud providers like AWS. The short answer is: ip route get 8.8.8.Vagrant is a development environment automation tool. If you care about reaching the public internet, using Google's 8.8.8.8 DNS server is pretty standard.

Depending on what IP you are trying to reach, 'my own ip address' (OP's words) will be different. You trim the output of ip route to get only the source IP. I don't mean to be a jerk, but there really is a right way and this is it.
