This repository provides a Vangrantfile and Ansible playbook that creates, configures and launchs a minifed environment (fedoidc example), as described in http://fedoidc.readthedocs.io/en/latest/minifed.html.
First, you have to edit the playbook.yml file and edit the hostname variable. You can leave it to localhost if you are just using it form your Vagrant host. But if you want to access it from outside, you should probably use your Vagrant host's name, so it can be reacheable.
The, you can create the VM and launch with
vagrant up
If you want to update the code to the latests version, you must vagrant provision. Note that this will remove any modification to the OP/RP configuration files you've done!
