我想在运行 docker-compose build 时使用 docker an，但出现标题错误。我的问题是导致这个问题的原因是什么？
这是 docker-compose.yml：
version: '3.8'
services:
nginx:
image: nginx:1.19.0-alpine
restart: on-failure
volumes:
- './apps/my-symfony-app/public:/usr/src/app'
- './docker/nginx/default.conf:/etc/nginx/conf.d/default.conf:ro'
ports:
- '80:80'
depends_on:
- php
php:
build:
context: .
dockerfile: .docker/php/Dockerfile
volumes:
- './apps/my-symfony-app/:/usr/src/app'
restart: on-failure
env_file:
- .env
user: 1000:1000
我已经添加了这个 Dockerfile。也许这与这个文件有关，我不确定。
