Docker – 具有自定义conf的nginx

当运行docker-compose.yml docker-compose up和下面docker-compose.yml文件时， nginx在启动后立即退出。 当我删除以下行：

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

nginx不会立即退出。

docker-compose.yml

 version: '3' services: nginx: image: nginx ports: - '8080:80' volumes: - ./nginx/log:/var/log/nginx - ./nginx/config:/etc/nginx/conf.d - ../wordpress:/var/www/wordpress php: image: php:fpm ports: - 9000:9000 mysql: image: mysql ports: - "3306:3306" environment: MYSQL_ROOT_PASSWORD: secret volumes: - ./mysql/data:/var/lib/mysql 

我怎样才能让nginx运行一个自定义的/etc/nginx/conf.d/default.conf ？
