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 .
