docker-compose up -d nginx                     构建建启动nignx容器

docker-compose down                              删除所有nginx容器,镜像

docker-compose ps                                   显示所有容器

docker-compose restart nginx                   重新启动nginx容器

docker-compose run --no-deps --rm php-fpm php -v  在php-fpm中不启动关联容器，并容器执行php -v 执行完成后删除容器

docker-compose build nginx                     构建镜像 。

docker-compose logs  nginx                     查看nginx的日志

docker-compose events --json nginx       以json的形式输出nginx的docker日志

docker-compose pause nginx                 暂停nignx容器

docker-compose unpause nginx             恢复ningx容器

docker-compose rm nginx                       删除容器（删除前必须关闭容器）
