• config.yml: You can use config.yml to define the nodes to use and to make global settings for the Vagrant environment without modifying the Vagrantfile.
• Vagrantfile: Every Vagrant environment needs a Vagrantfile. The primary function of the Vagrantfile is to describe the type of machines required for a project, and how to configure and provision these machines.
• provisioning/bootstrap.yml: Ansible playbook for initial provisioning of all nodes, including the master node.
• provisioning/requirements.yml: This file contains the required Ansible roles needed by bootstrap.yml.
• provisioning/inventory.ini: Manually configured Ansible inventory file that is used only if the dynamic_inventory option is set to false in config.yml (see Configuration Options).
• provisioning/roles: Directory for the Ansible Roles.
• provisioning/test-playbook: Shell script for testing new playbooks and roles
• provisioning/vagrant.ini: Dynamically configured Ansible inventory file used when config.yml has the dynamic_inventory option set to true, which is the default (see Configuration Options).
