错误 - nginx: [emerg] "server" 指令在 /etc/nginx/nginx.conf:1 中是不允许的

Question

I created a docker-compose.yml file with Nginx, PHP-7.4-fpm, PhpMyAdmin and MariaDB, the execution of my docker-compose.yml has been deployed successfully but the Nginx container has an error:

nginx: [emerg] "server" directive is not allowed here in /etc/nginx/nginx.conf:1

.docker/docker-compose.yml:

    server_name monsite.local;
    root /code;

    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php;
    }

    location ~ \.php$ {
        try_files $uri /index.php =404;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    error_log /var/log/nginx/project_error.log;
    access_log /var/log/nginx/project_access.log;
}

I don't understand why I have this error, can you help me please ?

Thank you in advance

In your context you need to wrap server in http block. Or move you config file not by replacing the default config file, but rather replacing a default server config located in /etc/nginx/conf.d/ So you can use something like

        - ./nginx.conf:/etc/nginx/conf.d/default.conf

for volumes for nginx. That will rewrite your default server config. You can also copy it to sites-enabled folder if you planning to use multiple config files.

Or you can modify your nginx config, by starting with wrapping it with http block
