基本目录结构

前置条件

1. windows正常docker服务启动

pom插件配置

Dockerfile文件配置

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ADD docker-demo-0.0.1.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

执行插件命令

项目路径下执行 mvn clean package docker:build命令进行打包且构建镜像

查看结果

上面是利用插件进行构建镜像的方式；如果没有使用该插件可以直接将执行mvn package后生成的jar包，复制到含有Dockerfile的文件夹中，然后执行docker命令docker build -t docker-spring-demo:0.0.1 . 构建镜像

踩坑记录

1. Dockerfile写成DockerFile后，执行失败
   2.maven中<include>${project.build.finalName}.jar</include>的.jar漏写之后，执行命令后一直找不到jar包

win10环境下使用docker部署spring-boot项目
