Dockerfile文件如下：
FROM ubuntu #基礎鏡像
RUN apt-get update #更新apt
RUN apt-get -y install nginx #安裝nginx
VOLUME ["data"] #可選，掛載目錄
EXPOSE 80 #暴露80端口
CMD nginx -g "daemon off;" #后台運行nginx命令，在運行容器時執行
構建鏡像：
sudo docker build -t ubun/nginx .
指定名稱為ubun/nginx，在當前目錄下搜索Dockerfile
運行容器：
docker run -d --name nginx -p 80:80 ubun/nginx
綁定本地80端口到容器的80端口
測試：
curl 127.0.0.1
若返回以下內容則是成功：
