or set the ssh_public_key_path option on the ansible-playbook command line by
setting the variable. Example: "-e ssh_public_key_path=~/.ssh/id_rsa.pub"
If the hosts need to be re-deployed, the dynamic redeploy playbook may be used::
export BIFROST_INVENTORY_SOURCE=/tmp/baremetal.json
ansible-playbook -vvvv -i inventory/bifrost_inventory.py redeploy-dynamic.yaml
This playbook will undeploy the hosts, followed by a deployment, allowing
a configurable timeout for the hosts to transition in each step.
Testing with a single command

# 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, csv, 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.

features:
- A new playbook was added to redeploy nodes.
The playbook transitions each node's provision state
to 'available', waiting for the nodes to reach
that state. Next, the playbook deploys the
nodes, waiting for the nodes to reach provision
state 'active'. The playbook is redeploy-dynamic.yaml
in the playbooks directory.
