2、Dockerfile文件内容：

FROM java:8
MAINTAINER 457030599@qq.com
VOLUME /tmp
ARG JAR_FILE
COPY guns-rest-0.0.1.jar app.jar
RUN bash -c 'touch /app.jar'
EXPOSE 80
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","-Denv=DEV","/app.jar"]

3、远程登陆服务器，执行脚本

docker stop guns-rest #停掉容器
docker rm guns-rest #删除容器
\cp /opt/data/jenkins/workspace/my-wechat/guns-rest/target/guns-rest-0.0.1.jar /opt/data/jenkins/workspace/my-wechat/docker/guns-rest-0.0.1.jar #jar包复制到dockerfile相同目录下
cd /opt/data/jenkins/workspace/my-wechat/guns-rest/docker
docker build -t hsshy/guns-rest . #构建镜像
docker run --name guns-rest -p 80:80 -d hsshy/guns-rest #运行容器
