Chapter 23. Configuring Direct Deploy

Create or modify a custom environment file /home/stack/undercloud_custom_env.yaml and specify the IronicDefaultDeployInterface.

parameter_defaults:
  IronicDefaultDeployInterface: direct

By default, the Bare Metal service (ironic) agent on each node obtains the image stored in the Object Storage service (swift) through a HTTP link. Alternatively, ironic can stream this image directly to the node through the ironic-conductor HTTP server. To change the service that provides the image, set the IronicImageDownloadSource to http in the /home/stack/undercloud_custom_env.yaml file:

parameter_defaults:
  IronicDefaultDeployInterface: direct
  IronicImageDownloadSource: http

Include the custom environment file in the DEFAULT section of the undercloud.conf file.

custom_env_files = /home/stack/undercloud_custom_env.yaml

Perform the undercloud installation:

$ openstack undercloud install
