我正在尝试创建一个Dockerfile来构建我们的可重用镜像。
FROM crystaltwix/centos-mono
MAINTAINER crystaltwix
ADD ./rpms/MyRpm.rpm ./rpms
RUN yum --nogpgcheck localinstall ./rpms/MyRpm.rpm我得到一个错误
Cannot open: ./rpms/Myrpm.rpm. Skipping.我不明白的是，如果我在容器中运行镜像，为什么它不工作：
sudo docker run -i -t -v /home/crystaltwix/projects/rpms:/opt/rpms crystaltwix/centos-mono /bin/bash然后在容器的shell中，我执行相同的命令：
yum --nogpgcheck localinstall ./rpms/MyRpm.rpm这很好用。只是在我的Dockerfile中不起作用。我是否错过了Dockerfile构建镜像的方式的一些特定内容？

来自https://docs.docker.com/reference/builder/#add:
If <src> is any other kind of file, it is copied individually along with its metadata. In this case, if <dest> ends with a trailing slash /, it will be considered a directory and the contents of <src> will be written at <dest>/base(<src>).ADD ./rpms/MyRpm.rpm ./rpms会导致./rpms成为MyRpm.rpm文件。请改用ADD ./rpms/MyRpm.rpm ./rpms/。
