========================================
|
|
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.
