| reference | Node Labels Populated By The Kubelet | 40 |
Kubernetes {{< glossary_tooltip text="nodes" term_id="node" >}} come pre-populated with a standard set of {{< glossary_tooltip text="labels" term_id="label" >}}.
You can also set your own labels on nodes, either through the kubelet configuration or using the Kubernetes API.
Preset labels
The preset labels that Kubernetes sets on nodes are:
kubernetes.io/archkubernetes.io/hostnamekubernetes.io/osnode.kubernetes.io/instance-type(if known to the kubelet – Kubernetes may not have this information to set the label)topology.kubernetes.io/region(if known to the kubelet – Kubernetes may not have this information to set the label)topology.kubernetes.io/zone(if known to the kubelet – Kubernetes may not have this information to set the label)
{{}}
The value of these labels is cloud provider specific and is not guaranteed to be reliable.
For example, the value of kubernetes.io/hostname may be the same as the node name in some environments
and a different value in other environments.
