Question

我正在使用以下Dockerfile：

FROM centos
RUN yum -y -q install epel-release && yum -y -q update && yum clean all \
&& yum -y -q install python-pip
COPY requirements.txt /tmp/
RUN pip install -q pyvmomi==6.5.0.2017.5.post1

不确定为什么它在使用docker 17.09.0-ce的MacOS上运行正常，但它没有将CentOS与docker 17.11.0-ce-rc3一起使用。 pip安装中有一个错误，在这个例子中我使用pyvmomi但是我和其他包有类似的错误。

知道为什么同一个图像无法在不同的操作系统上构建？此外，我尝试使用ubuntu作为docker镜像，并在两者中都很完美。感谢。

Answer 1

错误是由chardet安装的epel-release软件包之间的冲突引起的请参阅epel package list以及pyvmomi特定版本所需的版本。

使用操作系统软件包版本来避免此冲突，即yum -q install python2-pyvmomi

此错误的非确定性外观将归因于epel-release中的包版本中的上游更改以及pip install中使用的更改

Docker映像在CentOS中失败，但适用于MacOS
