Vagrant is a tool for building and distributing development environments.

VagrantPlugins::Kernel_V2::VMConfig#synced_folder

Defines a synced folder pair. This pair of folders will be synced
to/from the machine. Note that if the machine you're using doesn't
support multi-directional syncing (perhaps an rsync backed synced
folder) then the host is always synced to the guest but guest data
may not be synced back to the host.
