For those using zsh, they need to use quotes around the jsonpath argument, and remove the escape characters:

kubectl get nodes -o jsonpath="{.items[*].status.addresses[?(@.type=='ExternalIP')].address}"

is it possible to get this somehow as an environment variable in a deployment?

Like following from the downward API?

            - name: K8S_HOST_IP
              valueFrom:
                fieldRef:
                  fieldPath: status.hostIP
