我试着创建一个像这样的Docker服务：

version: '3'
services:
    app:
        image: php:8.2-fpm
        working_dir: "/var/www"
        volumes:
            - ./src:/var/www/html   
        networks:
            - internal
    nginx:
        restart: always
        image: nginx:latest
        ports:
            - "8080:80"
        volumes:
            - ./nginx:/etc/nginx/conf.d
            - ./src:/var/www/html
        depends_on:
            - app
        networks:
            - internal
networks:
    internal:
        name: internal

个字符
但是当我将app容器更改为apiapp时，出现了一个问题：

services:
    apiapp:
        image: php:8.2-fpm
        working_dir: "/var/www"
        volumes:
            - ./src:/var/www/html   
        networks:
            - internal
    nginx:
        restart: always
        image: nginx:latest
        ports:
            - "8080:80"
        volumes:
            - ./nginx:/etc/nginx/conf.d
            - ./src:/var/www/html
        depends_on:
            - apiapp
        networks:
            - internal
networks:
    internal:
        name: internal

$ docker-compose up -d
[+] Running 3/3
 ✔ Network internal           Created 0.0s 
 ✔ Container my-php-apiapp-1  Started 0.5s 
 ✔ Container my-php-nginx-1   Started 0.9s 
$ curl "http://localhost:8080"
curl: (52) Empty reply from server

的字符串
我先删除我的服务，然后输入docker-compose up -d，所以我假设my-php-app-1与my-php-apiapp-1无关，但我真的不知道为什么容器名称很重要。
我试图在Docker上找到““app”container”，但是Compose FAQs和Key features and use cases of Docker Compose对我的问题没有帮助。
Nginx设置文件基本上来自qiita上的一篇文章：

# https://qiita.com/shir01earn/items/f236c8280bb745dd6fb4
server {
    listen 80;
    root /var/www/html;
    index index.php;
    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
        if (!-f $document_root$fastcgi_script_name) {
            return 404;
        }
        fastcgi_param HTTP_PROXY "";
        fastcgi_pass app:9000; 
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
    location / {
        root /var/www/html;
        index index.php;
        try_files $uri $uri/ $uri.php /index.php?$query_string =404;
    }
}
