Docker镜像已成功构建但未运行

Question

您好我正在创建一个docker镜像并且它已经成功但是当我在app.jar上运行它时出错，我在构建过程中添加了它。有什么建议吗？

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"]
