Cool to see the authors of both vagrant and docker contribute their answers to the question.<p>I&#x27;ve actually been running docker containers inside of vagrant for a few months now at work. We&#x27;re moving to a service oriented architecture and the more services we add the more complex it becomes for us to get new engineers up and running on their development environment.<p>We&#x27;re using docker-compose to orchestrate all of the services inside of vagrant and it&#x27;s been working so far for our development environments. Our next step is to switch our staging servers over to docker containers once we get all our engineers running vagrant + docker locally.
