Auto Push Spring Boot App Image on Docker Hub Repository# 9561826040

 In this we will see how to create image and push on docker hub automatically. 

I create simple Hello_World_Docker spring boot application and created one controller in it.

package com.example.demo;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

@RestController

public class WelcomeController {

@RequestMapping("/wish")

public String Wish() {

return "HELLO GVOIND MANTRI";

}

}

command :  package dockerfile:build

command :  package dockerfile:push

command :  clean install
