   @dimberman We are using this to add variables from the dagrun conf to labels, in order to use them to filter pods and logs.
   
   It looks like:
   ```
   # ensure_valid_pod_label is a user-defined macro to make sure the value is a valid Kubernetes pod label
   
   task = KubernetesPodOperator(
       ...,
       labels={
           "is_airflow_pod": "true",
           "run_id": "{{ ensure_valid_pod_label(run_id) }}",
           "element_id": "{{ ensure_valid_pod_label(dag_run.conf.element_id) }}",
           "start_date": "{{ ensure_valid_pod_label(dag_run.conf.start_date) }}",
           "end_date": "{{ ensure_valid_pod_label(dag_run.conf.end_date) }}",
           },
       )
   ```
   I'm not familiar with `pod_template_file`, so I'm not sure if it would be possible.
