Развертывание файла war на Jetty в Docker: ошибка 404 Не найдено, но контексты известны

Question

Я прохожу учебник Hello World для Jetty здесь

Согласно руководству, я должен иметь доступ к нему по адресу: 8080 / hello-world / hello (hello-world происходит из идентификатора артефакта в pom.xml, а hello - из web.xml). Когда я пытаюсь это сделать, я получаю ошибку HTTP 404.

Когда я пытаюсь получить доступ к веб-серверу с http://172.17.0.2:8080/ (172.17.0.2 - это IP-адрес контейнера), я получаю следующую информацию:

Error 404 - Not Found.
No context on this server matched or handled this request.
Contexts known to this server are:

 - /hello-world-0.1-SNAPSHOT ---> o.e.j.w.WebAppContext@3224f60b{hello-world-0.1-SNAPSHOT,/hello-world-0.1-SNAPSHOT,file:///tmp/jetty-0.0.0.0-8080-hello-world-0.1-SNAPSHOT.war-_hello-world-0.1-SNAPSHOT-any-4591378293374546697.dir/webapp/,AVAILABLE}{/hello-world-0.1-SNAPSHOT.war}

Мой Dockerfile:

FROM openjdk:10 as step-one                                                                                                 

COPY ./ /var/www/java/
WORKDIR /var/www/java

RUN apt-get update -y && apt-get install -y maven

RUN mvn clean package -X

FROM jetty as step-two

COPY --from=step-one /var/www/java/target/hello-world-0.1-SNAPSHOT.war /var/lib/jetty/webapps/

ENTRYPOINT ["java"]
CMD ["-jar", "/usr/local/jetty/start.jar", "--create-startd=jmx, stats"]

EXPOSE 8080

Мой web.xml:
