docker - 如何调试 nvidia-docker build 中缺少的路径

问题描述

我正在创建一个 nvidia-docker 映像，Dockerfile 中包含以下内容：

RUN curl -so /miniconda.sh https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh  && chmod +x /miniconda.sh  && /miniconda.sh -b -p /miniconda  && rm /miniconda.sh
ENV PATH=/miniconda/bin:$PATH
#this is stored in cache ---> fa383a2e1344
# check path
RUN /miniconda/bin/conda

我收到以下错误：

/bin/sh: 1: /miniconda/bin/conda: not found
The command '/bin/sh -c /miniconda/bin/conda' returned a non-zero code: 127

当我使用以下方法测试路径时：

nvidia-docker run --rm fa383a2e1344 ls

然后 /miniconda 不存在因此错误。

然后我更改了 Dockerfile 以将 /miniconda 替换为 env var 路径，即：

ENV CONDA_DIR $HOME/miniconda
# Install Miniconda
RUN curl -so /miniconda.sh https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh \
 && chmod +x /miniconda.sh \
 && /miniconda.sh -b -p CONDA_DIR \
 && rm /miniconda.sh

ENV PATH=$CONDA_DIR:$PATH

# check path
RUN $CONDA_DIR/conda

并得到错误：

/bin/sh: 1: /miniconda/conda: not found
The command '/bin/sh -c $CONDA_DIR/conda' returned a non-zero code: 127

解决方案

我能够通过设置当前目录的路径而不是点击来让它工作/

   WORKDIR /miniconda
   RUN curl -so ./miniconda.sh https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh \
    && chmod +x ./miniconda.sh \
    && ./miniconda.sh -b -p CONDA_DIR

这是构建结果供参考
