无法在 Dockerfile 中运行 2 个 conda 命令

Question

我有一个 docker 文件，例如：

FROM conda/miniconda3-centos7
WORKDIR /tmp 
COPY app/ /tmp 
RUN conda install gcc_linux-64 
RUN conda install gxx_linux-64 
CMD ["python", "Hello_World.py"]

代码在第一个 RUN conda 命令后卡住。我得到的错误是：

WARNING: The conda.compat module is deprecated and will be removed in a future release.


==> WARNING: A newer version of conda exists. <==
    current version: 4.6.11
    latest version: 4.9.2

Please update conda by running

$ conda update -n base -c defaults conda

Step 7/8 : RUN conda install gxx_linux-64
 ---> Running in 94166fbfff2a
Traceback (most recent call last):
  File "/usr/local/bin/conda", line 12, in <module>
    from conda.cli import main
ModuleNotFoundError: No module named 'conda'
The command '/bin/sh -c conda install gxx_linux-64' returned a non-zero code: 1

你能推荐一下吗？

在 Dockerfile 中添加 conda update -n base -c defaults conda 可以解决上述问题。

您也可以考虑使用&& 来优化 docker 镜像的创建。 Read more about it here.

优化的 Dockerfile 将是：

FROM conda/miniconda3-centos7
WORKDIR /arnav
COPY app/ /arnav
RUN conda update -n base -c defaults conda \
    && conda install gcc_linux-64 && conda install gxx_linux-64
CMD ["python", "Hello_World.py"]
