Can I configure Vagrant to setup a synced folder only if it exists on the host?

Question

For our developers ~/Development/framework_repo is normally available on the host, but for our designers it wouldn't be. Is it possible to conditionally configure a synced folder depending on it's availability on the host?

Answer 1

Since the Vagrantfile is a Ruby script, you could check for the presence of the directory with File.directory(), and enable the shared folder only if needed.

For example:

Vagrant.configure("2") do |config|
  if File.directory?(File.expand_path("~/Development/framework_repo"))
    config.vm.synced_folder "~/Development/framework_repo", "/guest/path"
  end
end
