Docker镜像成功构build但未运行

你好，我正在创build一个docker图像，它是成功的，但是当我运行它错误了我在构build过程中添加的app.jar。 有什么build议么？

Docker文件内容

FROM openjdk:alpine VOLUME /tmp ADD cta-details-service-1.0.0.jar app.jar ADD start.sh start.sh RUN apk add --update bash && rm -rf /var/cache/apk/* RUN bash -c 'touch /app.jar' RUN bash -c 'chmod +x /start.sh' EXPOSE 8090 ENTRYPOINT ["/bin/bash", "/start.sh"]
