如何在airflow kuber pod operator中设置dns配置？

apiVersion: v1
kind: ConfigMap
metadata:
  name: dns-config
data:
  resolv.conf: |
    nameserver 8.8.8.8
    search mydomain.com

from airflow.contrib.operators.kubernetes_pod_operator import KubernetesPodOperator

dns_config_volume = {
    'name': 'dns-config',
    'configMap': {
        'name': 'dns-config'
    }
}

dns_config_volume_mount = {
    'name': 'dns-config',
    'mountPath': '/etc/resolv.conf',
    'subPath': 'resolv.conf'
}

task = KubernetesPodOperator(
    task_id='dns-task',
    name='dns-pod',
    image='your_image',
    volumes=[dns_config_volume],
    volume_mounts=[dns_config_volume_mount],
    # other parameters...
)
