Hi all,

I am running a multi-machine vagrant which in the first machine I am preparing a gateway and a second one would be the actual machine “behind” the gateway. Is there a way to trigger starting the second machine when the provisioning of the first one ends (I assume ruby and vagrant trigger for this)…?

Hey there,  
I don’t think this is currently possible. There isn’t a way to have a relationship between machines and how they might be started. You might be tempted to run vagrant commands in a trigger. However, that will cause issues since only one Vagrant process can run at a time.
