问题：
通过 docker build构建SpringBoot镜像时出现如下问题：

[root@localhost docker]#  docker build -t example:1.0.0 .

方案：
该问题由网络不好产生，可以更换网络环境尝试一下，如果还是没有解决，可以通过修改dockerfile文件FROM配置尝试一下，如下所示：文章来源地址https://www.toymoban.com/news/detail-627712.html

FROM openjdk:8

MAINTAINER GaoHuanjie

VOLUME /tmp

ADD dubhe-0.0.1-SNAPSHOT.jar app.jar

RUN bash -c 'touch /app.jar'
