Docker部署springboot项目实例解析

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
  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

[root@topcheer docker]# docker build -f Dockerfile -t boot .
