這篇文章主要介紹了docker部署springboot項目實例解析,文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值,需要的朋友可以參考下

啟動類
@SpringBootApplication
@Controller
public class DockerApplication {
public static void main(String[] args) {
SpringApplication.run(DockerApplication.class, args);
}
@RequestMapping("/user/find")
@ResponseBody
public Object findUser(){
Map<String, String > map = new HashMap<>();
map.put("name", "xdclass.net");
map.put("age","28");
return map;
}
}
由于harbor沒有安裝，無法把鏡像推到私有鏡像倉庫上，所以先手動執行。
mvn install,然后把dockerfile和jar包放到一起
[root@topcheer docker]# ll

-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]#
編譯成鏡像并啟動
[root@topcheer docker]# docker build -f Dockerfile -t boot .
