  • 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<String, String > 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 .
