A Vagrantfile for running the Learn to manage a basic Ubuntu web application Chef tutorial locally. Be sure to replace the name of the NIC bridge: 'Dell GigabitEthernet' with your own NIC name. After you vagrant up, you should be able to run all the provisioning steps in the tutorial using the vagrant provided identity file as such:
knife ssh 10.0.0.101 'sudo chef-client' --manual-list --ssh-user vagrant --identity-file ".\.vagrant\machines\node\virtualbox\private_key"
