空路徑返回進入新的碼頭工人形象

時，我已經寫了Dockerfile爲建設一個碼頭工人形象：空路徑返回進入新的碼頭工人形象

RUN echo $PATH 
RUN echo "its chowning the USER directory that seems to break path" 
#RUN sudo chown -R docker $HOME

RUN sudo /opt/conda/bin/python getNeuroML.py 
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指定的圖像與

$docker build .

我找到圖片ID爲最新版本，並輸入它使用：

$docker run -it d10bd1b2c2bb /bin/bash

但是，當我進入碼頭圖像我發現環境變量PATH的內容是空的。

最終命令是：

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語句的輸出是適當的。在構建圖像的過程中，碼頭環境變量似乎很好，但是，只有在輸入泊塢窗圖像時纔會出現問題。

如果這些最終的Docker命令被省略，那麼當我進入新鮮鑄造的圖像時，PATH變量仍然是一個空字符串。

我不知道是否有人知道發生了什麼問題？

感謝您的任何建議。

只有與以下內容類似的語句： ENV PATH/opt/conda/bin/conda：/ opt/conda/bin/python：$ PATH 應該用於設置環境變量。路徑變量可以在生成過程中檢查： RUN echo $ PATH 但是在構建過程中命令如 conda和python可能無法按預期工作，但PATH變量將在您輸入泊塢窗時被正確更新圖片。
