The Kubelet populates this with `runtime.GOOS` as defined by Go. This can be handy if you are mixing operating systems in your cluster (for example: mixing Linux and Windows nodes).

When the `kubernetes.io/os` label value for a Pod does not match the label value on a Node,
the kubelet on the node will not admit the Pod. However, this is not taken into account by
the kube-scheduler. Alternatively, the kubelet refuses to run a Pod where you have specified a Pod OS, if
this isn't the same as the operating system for the node where that kubelet is running. Just
look for [Pods OS](/docs/concepts/workloads/pods/#pod-os) for more details.
