Add custom volumeMount into Airflow worker pods (with k8s Executor)

Sorry i'd to answer my own question. Maybe will help someone. Inside the dag file, where I define the task, I simply had to add the executor_config as follows;

        IngestionStatusSensor(            task_id=...,            executor_config={"KubernetesExecutor": {                                  "image": "airflow:runner2",                                  "volume_mounts": [                                      {                                          "name": "airflow-dags",                                          "mountPath": "/usr/local/airflow/libs",                                          "subPath": "airflow/development/libs"                                      },                                      {                                          "name": "airflow-dags",                                          "mountPath": "/usr/local/airflow/plugins",                                          "subPath": "airflow/development/plugins"                                      }],                                  }                             },            dag=dag,            ingestion_feed=table,            poke_interval=60 * 30,            offset=0,            start_date=start_date        )

where airflow-dags volume is already defined by pod creator that claims the PVC defined in configs under kubernetes section of airflow.conf e.g. dags_volume_claim = airflow-pvc.
