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 @controller public class dockerapplication { public static void main(string[] args) { springapplication.run(dockerapplication.class, args); } @requestmapping("/user/find") @responsebody public object finduser(){ mapmap = 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 dockerfile from java:8 volume /tmp add docker.jar app.jar run bash -c 'touch /app.jar' expose 8080 entrypoint ["java","-djava.security.egd=file:/dev/./urandom","-jar","/app.jar"] [root@topcheer docker]#
编译成镜像并启动
