【问题描述】：
我有以下版本的 compose：
docker-compose version 1.25.4, build 8d51620a
docker-py version: 4.1.0
CPython version: 3.7.5
不可能更新docker-compose，因为它属于asustor NAS server - 至少暂时我不知道如何将其更新为docker compose 2.0。如果我愿意，我的.yaml 文件可以工作 - 我在 ym local PC 上检查了它。知道我需要将我当前的yaml 文件更改为适合docker-compose 1.25，这就是它在下面的样子。谁能告诉我我应该改变什么以避免出现这样的问题：docker-compose up

# Basic Airflow cluster configuration for CeleryExecutor with Redis and PostgreSQL.
#
# WARNING: This configuration is for local development. Do not use it in a production deployment.
#
# This configuration supports basic configuration using environment variables or an .env file
# The following variables are supported:
#
# AIRFLOW_IMAGE_NAME - Docker image name used to run Airflow.
# Default: apache/airflow:master-python3.8
# AIRFLOW_UID - User ID in Airflow containers
# Default: 50000
# AIRFLOW_GID - Group ID in Airflow containers
# Default: 0
#
# Those configurations are useful mostly in case of standalone testing/running Airflow in test/try-out mode
#
# _AIRFLOW_WWW_USER_USERNAME - Username for the administrator account (if requested).
# Default: airflow
# _AIRFLOW_WWW_USER_PASSWORD - Password for the administrator account (if requested).
# Default: airflow
