DOCKER。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 idea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 .

图像hello-world正常运行。 我创建可执行jar和Dockerfile。输入创建图像的命令时，出现以下错误：

error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.40/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&do ckerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&session=jauqgloaecpwv5hch49bgfcak&shmsize=0&t=week10&target=&ulimits=null&version=1: open //./pipe/docker_en gine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

Dockerfile：

FROM openjdk:8-jdk-alpine
ADD target/week10-1.0-SNAPSHOT.jar week10.jar
EXPOSE 8080
ENTRYPOINT ["java","-jar","week10.jar"]
