Docker在推送到存儲庫時顯示驗證錯誤

Question

我在IntelliJ中有一個簡單的HelloWorld Spring Boot應用程序。

這是我的代碼：

@Configuration 
@ComponentScan 
@EnableAutoConfiguration 
@SpringBootApplication 
public class App extends SpringBootServletInitializer { 

    @Override 
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
     return application.sources(App.class); 
    } 

    public static void main(String[] args) { 
     SpringApplication.run(App.class, args); 
    } 
} 


//takes input and navigates to that address 
@RestController 
class GreetingController { 

    @RequestMapping("/hello/{name}") 
    String hello(@PathVariable String name) { 
     return "Hello, welcome " + name + "!"; 
    } 
} 

@RestController 
class IndexController implements ErrorController { 

    private static final String PATH = "/error"; 

    @RequestMapping(value = PATH) 
    public String error() { 
     return "You wanted to go to invalid URL. Please check again."; 
    } 

    @Override 
    public String getErrorPath() { 
     return PATH; 
    } 
} 

這是我的pom.xml：

</project> 

我按照這個教程：https://spring.io/guides/gs/spring-boot-docker/

我想部署該應用泊塢窗，以下教程中，我在主/ docker/Dockerfile中創建了一個docker文件

FROM frolvlad/alpine-oraclejdk8:slim 
VOLUME /tmp 
ADD sudo-1.0-SNAPSHOT.jar app.jar 
RUN sh -c 'touch /app.jar' 
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"] 

如果是的IntelliJ

MVN包搬運工的終端運行的那些命令：建立-e

和它tryings後成功創建。當在Linux termnal我跑泊塢窗圖片，我看到：

docker images 
REPOSITORY     TAG     IMAGE ID   CREATED    SIZE 
springio/hllowrlddckr  latest    0aa30f27c704  40 seconds ago  195.3 MB 

按照本教程中，我需要推到回購本：

sudo docker push springio/hllowrlddckr 

但它給錯誤使用或不須藤：

sudo docker push springio/hllowrlddckr 
The push refers to a repository [docker.io/springio/hllowrlddckr]

什麼是錯誤？

Answer 1

正如你可以在提到tutorial閱讀：

你不必把你的新崛起的碼頭工人形象實際運行它。

您看到的錯誤也在本教程中解釋：您無權推送到frolvlad存儲庫。
