Modify the deployment model

Modify the deployment model¶

To use the OpenStack Bare Metal service, you need to modify your Reclass model before deploying a new OpenStack environment. You can also deploy the OpenStack Bare Metal service in the existing OpenStack environment.

As bare-metal configurations vary, this section provides examples of deployment model modifications. You may need to tailor them for your specific use case.

The configuration examples in this section presuppose the following:

The OpenStack Bare Metal API service runs on the OpenStack Controller node
The Bare Metal service for ironic-conductor and other services per the bare-metal role reside on the bmt01, bmt02, and bmt03 nodes
Separate flat network is used between the bmt* and gtw* nodes
The network configuration:
- Control network: 10.11.0.0/16
- Bare-metal network: 10.13.0.0/16
- Bare-metal interface: ens6

To modify the deployment model:

Select from the following options:
- For the MCP versions prior to the 2019.2.6 maintenance update, Create a deployment metadata model.
- For the MCP versions 2019.2.6 and later, when creating a deployment model as described in Create a deployment metadata model, set the ironic_enabled parameter to True that will automatically add most of the Ironic parameters and classes described in the following steps.
Open the cluster level of your Reclass model.

In the ./openstack/init.yml file, add or update the following parameters to match your specific bare metal configuration:

Caution

The openstack_baremetal_neutron_subnet_ parameters must match your bare metal network settings. The bare metal nodes must be connected to the network before the deployment. During the deployment, MCP automatically registers this network in the OpenStack Networking service.
