这篇文章主要介绍了docker部署springboot项目实例解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

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
DemoprojectforSpringBoot


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
publicclassDockerApplication{
publicstaticvoidmain(String[]args){
SpringApplication.run(DockerApplication.class,args);
}
@RequestMapping("/user/find")
@ResponseBody
publicObjectfindUser(){
Mapmap=newHashMap<>();
map.put("name","xdclass.net");
map.put("age","28");
returnmap;
}
}

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。

mvninstall,然后把dockerfile和jar包放到一起

[root@topcheerdocker]#ll
总用量16452
-rw-r--r--1rootroot16810月2814:24Dockerfile
-rw-r--r--1rootroot1684248710月2814:17docker.jar
[root@topcheerdocker]#catDockerfile
FROMjava:8

RUNbash-c'touch/app.jar'
EXPOSE8080
ENTRYPOINT["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
[root@topcheerdocker]#

编译成镜像并启动

[root@topcheerdocker]#dockerbuild-fDockerfile-tboot.
