404 未找到 - Nginx - docker compose

這是一個非常標準的 docker 容器/設置

index.php``phpinfo();僅對 docker compose的標準呼叫無法在瀏覽器中提供此文件嗎？

所有 docker 服務容器都執行良好，例如，我可以在 shell 上登錄它們docker exec -it 3a234d1f384e sh。

如果你能幫助我在瀏覽器中提供文件？那太好了。提前致謝。

/nginx/conf.d/app.conf

server {
   listen 80;
   index index.php index.html;
   error_log  /var/log/nginx/error.log;
   access_log /var/log/nginx/access.log;
   root /var/www/public;
   location ~ \.php$ {
       try_files $uri =404;
       fastcgi_split_path_info ^(.+\.php)(/.+)$;
       fastcgi_pass app_a:9000;
       fastcgi_index index.php;
       include fastcgi_params;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       fastcgi_param PATH_INFO $fastcgi_path_info;
   }
   location / {
       try_files $uri $uri/ /index.php?$query_string;
       gzip_static on;
   }
}

對於我上面的特定設置。我認為我的錯誤是index.php需要在public文件夾內並從那裡提供。
