通过maven 打docker 镜像包，出错ADD failed: stat /var/lib/docker/tmp/docker-builderXXXXXX: no such file or dir

直接用maven打包成docker镜像的时候，就报这个错，

最开始以为是 <artifactId>spring-boot-starter-parent</artifactId><version>2.0.3.RELEASE</version> 版本问题，改成1.5.6版本就可能顺利打包，最后排查到是打包文件名不一致，坑啊

其实就是pom.xml文件与dockerFile生成镜像文件名不一致，

pom.xml里会自带后缀名，就是版本号，黑色字体要注意，

<groupId>com.example.euraka</groupId>
<artifactId>demoServerClient</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

dcokerfile 文件里 ADD testeuraka-0.0.1.jar /app/app.jar 是这样

这两个地方统一就OK 所以我把pom.xml里的SNAPSHOT后缀去掉了

ADD testeuraka-0.0.1-SNAPSHOT.jar app.jar 要和pom的<artifactId>testeuraka</artifactId>

第一次打包镜像下载的东西很多，也是报错

这是第三次才出现的错误，统统把他们放在一起处理

BUILD FAILURE

Exception caught: ADD failed: stat /var/lib/docker/tmp/docker-builder974844977/testeuraka-1.0.0.jar: no such file or directory -> [Help 1]

以下是我的正确配置

Dockerfile

FROM java:8
VOLUME /tmp
RUN mkdir /app
ADD testeuraka-0.0.1.jar /app/app.jar
ADD runboot.sh /app/
RUN bash -c 'touch /app/app.jar'
WORKDIR /app
RUN chmod a+x runboot.sh
RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
echo 'Asia/Shanghai' >/etc/timezone
EXPOSE 5010

CMD /app/runboot.sh

下面是pom.xml
