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
<?xml version="1.0" encoding="UTF-8"?>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(){
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 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
