There are a couple awesome enhancements that would benefit from being documented here: 1. `spec.nodeName` for obtaining the host name 2. `spec.serviceAccountName` for obtaining the name of the service account the pod is running under Right now these enhancements are documented only in a couple of issues and pull requests: 1. https://github.com/kubernetes/kubernetes/pull/27880 2. https://github.com/kubernetes/kubernetes/issues/24657 3. https://github.com/kubernetes/kubernetes/issues/21317 I have verified the functionality in the latest codebase: 1. https://github.com/kubernetes/kubernetes/blob/master/pkg/api/v1/conversion.go#L200 Also updating downward-api/dapi-pod.yaml to add a concrete example.
