# Node Labels Populated By The Kubelet LLMS index: [llms.txt](/llms.txt) --- Kubernetes come pre-populated with a standard set of . 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/arch`](/docs/reference/labels-annotations-taints/#kubernetes-io-arch) * [`kubernetes.io/hostname`](/docs/reference/labels-annotations-taints/#kubernetesiohostname) * [`kubernetes.io/os`](/docs/reference/labels-annotations-taints/#kubernetes-io-os) * [`node.kubernetes.io/instance-type`](/docs/reference/labels-annotations-taints/#nodekubernetesioinstance-type) (if known to the kubelet – Kubernetes may not have this information to set the label) * [`topology.kubernetes.io/region`](/docs/reference/labels-annotations-taints/#topologykubernetesioregion) (if known to the kubelet – Kubernetes may not have this information to set the label) * [`topology.kubernetes.io/zone`](/docs/reference/labels-annotations-taints/#topologykubernetesiozone) (if known to the kubelet – Kubernetes may not have this information to set the label)

Note:

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.
