bifrost-deploy-nodes-dynamic
Provisions nodes based on inventory utilizing the os_ironic_node module installed by Bifrost.
Requirements
This role is expected to be executed on a node that the "ironic-install" node has been executed upon.
This role expects to be executed in a sequence with bifrost-configdrives-dynamic, however that is un-necessary IF the host has a dictionary named instance_info defined as that will be used as overriding values.
Role Variables
ironic_url: This is the URL to the ironic server. By default, this is set to "http://localhost:6385/"
network_interface: This is the network interface that the nodes receive DHCP/PXE/iPXE. This is utilized to generate the url that Ironic is configured with for image retrieval. This variable does not have a default in this role and expects to receive this information from the calling playbook.
deploy_image_filename: This is the filename of the image to deploy, which is combined with the network_interface variable to generate a URL used to set the Ironic instance image_source. This variable does not have a default in this role and expects to receive this information from the calling playbook.
deploy_image: This is the full path to the image to be deployed to the system. This is as Ironic requires the MD5 hash of the file to be deployed for validation during the deployment process. As a result of this requirement, the hash is automatically collected and submitted to Ironic with the node deployment request. This variable does not have a default in this role and expects to receive this information from the calling playbook.
instance_info: A dictionary containing the information to define an instance. By default, this is NOT expected to be defined, however if defined it is passed in whole to the deployment step. This value will override deploy_image_filename, deploy_image, and network_interface variables. Key-value pairs that are generally expected are image_source, image_checksum, root_gb, however, any supported key/value can be submitted to the API.
Dependencies
This role is intended to be executed upon a node that the ironic-install role has been executed upon. The configuration that is leveraged by this role utilizes a configuration drive to place network configuration and an SSH key on the newly deployed host. As such, the bifrost-configdrives role is required.
Example Playbook
NOTE: The example below assumes bifrost's default and that an instance_info variable is not defined.
- hosts: baremetal
connection: local
sudo: no
roles:
- role: bifrost-configdrives
- role: bifrost-setup-nodes
