So, you're using Vagrant, and maybe you've even read my earlier post on it, but your Vagrant box doesn't have everything you need. Or maybe it has too much, and you need something simpler. For instance, do you find yourself installing or removing packages or fixing packages to specific versions to get parity with your production platform? Or maybe you need more extensive auditing over your environment, such as when you (or your customer) can't trust a third-party box vendor. Or you need a way to clone a virtual machine for parity with the production environment. What are your options? In this blog post, I will explain what a box file is and how you can have more control over your Vagrant workflow by creating your own box. I will also introduce Packer as a tool to create a Vagrant box, and I will finish with an example for managing Vagrant box versions and distributing updates in a team setting.
