2) You will need to short circuit the ironic conductor process. An ideal place to do so is in ironic/drivers/modules/agent.py in the reboot_to_instance method. Temporarily short circuiting this step will force you to edit the MySQL database if you wish to re-deploy the node, but the node should stay online after IPA has completed deployment.

********************************
ssh_public_key_path is not valid
********************************
Bifrost requires that the user who executes bifrost have an SSH key in
their user home, or that the user defines a variable to tell bifrost where
to identify this file. Once this variable is defined to a valid file, the
deployment playbook can be re-run.
Generating a new ssh key
========================
See the manual page for the ssh-keygen command.
Defining a specific public key file
===================================
A user can define a specific public key file by utilizing the
ssh_public_key_path variable. This can be set in the
group_vars/inventory/all file, or on the ansible-playbook command
line utilizing the -e command line parameter.
Example::
ansible-playbook -i inventory/bifrost_inventory.py deploy-dynamic.yaml -e ssh_public_key_path=~/path/to/public/key/id_rsa.pub
NOTE: The matching private key will need to be utilized to login to the
machine deployed.
