# This playbook redeploys nodes by doing the following:
# 1) For each node in provision active state, unprovision the node
#    (ie. set the provision state to 'available'
# 2) Each node is given a configurable amount of time to transition
#    to 'available' state.
# 3) For each node now in 'available' state, deploy the node.
# 4) Each node is given a configurable amount of time to transition
#    to 'active' state.
#
# To utilize:
# export BIFROST_INVENTORY_SOURCE=<path to json or yaml data source>
# ansible-playbook -vvvv -i inventory/bifrost_inventory.py redeploy-dynamic.yaml
# NOTE: 'ironic' may be used as the data source, in which case ironic will
# will be queried for all the nodes.
#
# NOTE(TheJulia): The format of this example will cause hosts to be deployed
# utilizing DHCP on eth0 of Ubuntu/Debian hosts. It is advisable you build
# your deployment image with the dhcp-all-interfaces element when deploying
# other operating systems or if your target node has multiple ethernet
# interfaces.
