========================================

Use Labels to Identify OpenStack Nodes
|
|
========================================
|
|
|
|
The |prod-os| application is deployed on the nodes of the |prod| based on node
|
|
labels.
|
|
|
|
.. rubric:: |context|
|
|
|
|
Prior to initially installing the |prod-os| application or when adding nodes to
|
|
a |prod-os| deployment, you need to label the nodes appropriately for their
|
|
OpenStack role.

|
| **openstack-control-plane** | - Controller | Identifies a node to deploy openstack controller services on. |

|
|
| | | .. note:: |
|
|
| | | Adding or removing this label, or removing a node with this label from a cluster, triggers the regeneration and application of the helm chart overrides of the openstack application. |
