In that example, a provisioning script was defined within a Ruby variable: a string embedded within the Vagrantfile itself. When provisioning scripts begin growing to involve multiple steps or different logic, it can be difficult to create and modify scripts within a Vagrantfile. In most cases, we will want to remove the scripting from the Vagrantfile and instead execute provisioning from standalone scripts.
Before we create new provisioning scripts, let's recreate our html directory configuration of...
