常用命令:

docker-compose up -d nginx                     構建建啓動nignx容器

docker-compose exec nginx bash            登錄到nginx容器中

docker-compose down                              刪除所有nginx容器,鏡像

docker-compose ps                                   顯示所有容器

docker-compose restart nginx                   重新啓動nginx容器

docker-compose run --no-deps --rm php-fpm php -v  在php-fpm中不啓動關聯容器，並容器執行php -v 執行完成後刪除容器

docker-compose build nginx                     構建鏡像 。        

docker-compose build --no-cache nginx   不帶緩存的構建。

docker-compose logs  nginx                     查看nginx的日誌 

docker-compose logs -f nginx                   查看nginx的實時日誌

docker-compose config  -q                        驗證（docker-compose.yml）文件配置，當配置正確時，不輸出任何內容，當文件配置錯誤，輸出錯誤信息。 

docker-compose events --json nginx       以json的形式輸出nginx的docker日誌

docker-compose pause nginx                 暫停nignx容器

docker-compose unpause nginx             恢復ningx容器

docker-compose rm nginx                       刪除容器（刪除前必須關閉容器）

docker-compose stop nginx                    停止nignx容器

docker-compose start nginx                    啓動nignx容器
