我正在尝试设置DAG以运行Docker映像，但在运行时遇到问题。
我使用的是official Airflow docker-compose file。
我的DAG文件：

from airflow import DAG
from airflow.providers.docker.operators.docker import DockerOperator

from datetime import datetime

with DAG (
    "population", 
    start_date=datetime(2023, 1, 1), 
    schedule_interval='@daily', 
    catchup=False
) as dag:

    task_a = DockerOperator (
        task_id="task_a",
        image='population:1.0',
        command='python3 population.py',
        docker_url='unix://var/run/docker.sock',
        network_mode='host'
    )

当我访问Airflow UI并运行DAG时，收到错误消息no such file or directory is found。

错误：

我相信这与没有正确地在docker-compose.yml文件中挂载卷有关，但不确定我需要在文件中的哪里指定卷。
我看到这个question已经问过了，但是没有指定卷行应该去哪里。
