Laravel应用程序无法在本地写入文件，导致使用docker拒绝权限

我正在使用Docker创建一个laravel应用程序

我的Dockerfile：

#entrypoint will take CMD as an argument
ENTRYPOINT ["/entrypoint.sh"]

当我尝试提交表单时，出现以下错误：

The stream or file "/var/www/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied

我知道问题来自文件权限，我检查并获得存储：

drwxrwxr-x    5 www-data www-data      4096 Jul 19 12:20 storage

里面的目录和文件也是如此

My nginx.conf：

daemon off;
user www-data;
worker_processes 5;
pid /run/nginx.pid;

error_log /dev/stdout info;

    worker_connections 2048;

            # https off ? 
            fastcgi_param HTTPS off;
        }
    }
}

当我在存储上安装chmod 777时，它工作正常，但我知道这样做并不好。 我以为我的Web服务器使用的是www数据，但它不能写laravel.log 我应该做些什么来解决这个问题

经过一些测试，我发现我的应用程序laravel正在使用用户nobody编写文件，我真的不知道为什么服务器是由

www-data

运行的？@IvankaTodorova是的，当我在代码中放入一个var\u dump（get\u current\u user（））时，我有www-data
