Hey there - You will need to make your trigger a *command* trigger. By default, globally defined triggers run for each guest. If you wish for them to run once before or after a given command, you can make it a command trigger:
config.trigger.before :up, type: :command do |trigger| # configuration here end More information can be found in this subsection for vagrant triggers in the documentation: https://www.vagrantup.com/docs/triggers/usage.html#commands Thanks!
