空路径返回进入新的码头工人形象

时，我已经写了Dockerfile为建设一个码头工人形象：空路径返回进入新的码头工人形象

#start from the serial version of ubuntu NEURON+Python as if its a module 
# add mpi support 


#NEURON Dockerfile 
#Docker comments must be of this form.

ENV ADDITIONAL_PATH="/neuron/nrn-7.4/x86_64/bin" 
CMD export PATH=$PATH:$ADDITIONAL_PATH; /bin/echo -e "ADDITIONAL_PATH is $ADDITIONAL_PATH\nPATH is $PATH" 
RUN echo $PATH 
RUN echo $ADDITIONAL_PATH 

#WORKDIR /home/docker/git 
#RUN git clone

我建立由Dockerfile指定的图像与

$docker build .

我找到图片ID为最新版本，并输入它使用：

$docker run -it d10bd1b2c2bb /bin/bash

但是，当我进入码头图像我发现环境变量PATH的内容是空的。

最终命令是：

ENV ADDITIONAL_PATH="/neuron/nrn-7.4/x86_64/bin" 
CMD export PATH=$PATH:$ADDITIONAL_PATH; /bin/echo -e "ADDITIONAL_PATH is $ADDITIONAL_PATH\nPATH is $PATH" 
RUN echo $PATH 
RUN echo $ADDITIONAL_PATH

RUN所述echo语句的输出是适当的。在构建图像的过程中，码头环境变量似乎很好，但是，只有在输入泊坞窗图像时才会出现问题。

如果这些最终的Docker命令被省略，那么当我进入新鲜铸造的图像时，PATH变量仍然是一个空字符串。

我不知道是否有人知道发生了什么问题？

感谢您的任何建议。

只有与以下内容类似的语句： ENV PATH/opt/conda/bin/conda：/ opt/conda/bin/python：$ PATH 应该用于设置环境变量。路径变量可以在生成过程中检查： RUN echo $ PATH 但是在构建过程中命令如 conda和python可能无法按预期工作，但PATH变量将在您输入泊坞窗时被正确更新图片。
