码头工人.使用dockerfile创建映像时出错

我需要将我的项目容器化。我使用Intellij理念和我在Intellij终端中编写的所有命令。我使用的命令：

$ mvn package
$ docker build -f Dockerfile -t week10 .

图片你好世界工作正常。我创建了可执行jar和Dockerfile。当我输入创建图像的命令时，我得到以下错误：

连接期间出错：Posthttp://%2F%2F.%2管道%2Docker_engine/v.40/内部版本？buildargs=%7B%7D&cachefrom=%5B%5D&cgrouparent=&cpuperiod＝0&cpu阔ta＝0&cpusetcpus=&cpusetmems=&cpushares=0&做ckerfile=Dockerfile&标签=%7B%7D&内存＝0&memswap=0&networkmode=默认&rm＝1&session=jaukgloaecpwv5Hch49bgfcak&shmsize＝0&t=第10周&target=&ulimits=null&版本=1：打开///pipe/docker_en-gine:系统找不到该文件指定。在Windows上的默认守护进程配置中，docker客户端必须提升运行才能连接。此错误也可能表明docker守护进程没有运行。

Dockerfile:

EXPOSE 8080
