# Vagrantfile

#
# NOTE: Before attempting to use this file, follow the required Vagrant deployment steps:
# http://docs.vagrantup.com/v2/installation/index.html
#
# This file directs Vagrant on how to deploy the student VMs.
# It is possible to do a Single-VM or Multi-VM deployment based on
# the entries that are enabled in the "nodes" hash at the start of this file.
#
# By default, only the Single VM (allinone) deployment type is enabled.
# For Multi-VM, comment out 'allinone' and uncomment 'controller', 'compute', and 'network'
# Vagrant uses Virtualbox Guest Additions to modify VM properties
# (hostname, IP, resource allocation) according to VM function.
#
# Vagrant's Shell Provisioner receives deployment instructions from the following files:
#   allinone.sh
#   controller.sh
#   compute.sh
#   network.sh
# Removing these files without removing the Shell Provisioner command will cause Vagrant errors
#
# After determining the deployment type, build this environment by typing this command at the prompt:
# vagrant up
#
# Verify your VM status by typing this command at the prompt:
# vagrant status
#
# SSH to your VM by typing this command at the prompt:
# vagrant ssh vmname (ex: vagrant ssh compute)
#
# See the remaining OpenStack Training Labs code for more details at GitHub:
# https://github.com/openstack/openstack-manuals/tree/master/doc/training-guide/training-lab
