clusterLabels:
description: >
This attribute allows to associate arbitrary labels to clusters.
These can indicate special infrastructure capabilities (e.g., NW acceleration,
GPU compute, etc.). The intent of these labels is to serve as a set of
values that can help in application placement decisions.
clusterLabels follow the Kubernetes label key-value-nomenclature
(https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/).
It is recommended that labels follow a standardized meaning e.g. for node
features (https://kubernetes-sigs.github.io/node-feature-discovery/v0.9/get-started/features.html#table-of-contents).
Example:
ClusterLabels
