创建项目

pom.xml

  4.0.0      org.springframework.boot    spring-boot-starter-parent    2.1.9.release         com.topcheer  docker  0.0.1-snapshot  docker  demo project for spring boot      1.8    topcheer              org.springframework.boot      spring-boot-starter-web              org.springframework.boot      spring-boot-starter-test      test                          org.springframework.boot        spring-boot-maven-plugin                   com.spotify      docker-maven-plugin      1.0.0              ${docker.image.prefix}/${project.artifactid}        src/main/docker                              /            ${project.build.directory}            ${project.build.finalname}.jar                                  

启动类

@springbootapplication@controllerpublic class dockerapplication {  public static void main(string[] args) {    springapplication.run(dockerapplication.class, args);  }  @requestmapping("/user/find")  @responsebody  public object finduser(){    map map = new hashmap<>();    map.put("name", "xdclass.net");    map.put("age","28");    return map;  }}

由于harbor没有安装，无法把镜像推到私有镜像仓库上，所以先手动执行。

mvn install,然后把dockerfile和jar包放到一起

[root@topcheer docker]# ll总用量 16452-rw-r--r-- 1 root root   168 10月 28 14:24 dockerfile-rw-r--r-- 1 root root 16842487 10月 28 14:17 docker.jar[root@topcheer docker]# cat dockerfilefrom java:8volume /tmpadd docker.jar app.jarrun bash -c 'touch /app.jar'expose 8080entrypoint ["java","-djava.security.egd=file:/dev/./urandom","-jar","/app.jar"][root@topcheer docker]#

编译成镜像并启动
