Dockerfile构建突然失败

Question

当运行命令低于 dockerfile 构建时，我正在尝试解决构建问题，例如我得到的错误：
1.

/bin/sh: 1: /opt/conda/bin/pip: not found
The command '/bin/sh -c wget -q https://repo.continuum.io/miniconda/Miniconda3-4.2.12-Linux-x86_64.sh -O /tmp/miniconda.sh  &&     echo 'd0c7c71cc5659e54ab51f2005a8d96f3 */tmp/miniconda.sh' | md5sum -c - &&     bash /tmp/miniconda.sh -f -b -p /opt/conda &&     /opt/conda/bin/conda install --yes -c conda-forge       python=3.5 sqlalchemy tornado jinja2 traitlets requests pip pycurl       nodejs configurable-http-proxy &&     /opt/conda/bin/pip install --upgrade pip &&     rm /tmp/miniconda.sh' returned a non-zero code: 127

2。当试图评论有问题的部分时，我们遇到了 npm 的另一个问题，例如： /bin/sh: 1: npm: not found

知道这里发生了什么吗？

Answer 1

由 conda forge 托管的最新 pip 包是 noarch/pip-20.0.2-py_2.tar.bz2，它缺少 bin 文件夹，因此调用 /opt/conda/bin/pip 会出现 /opt/conda/bin/pip: not found 错误。

我建议强制执行包的版本以防止更新版本导致构建错误，这将在不同的机器上实现确定性构建，从而节省时间，不必弄清楚是什么版本更改导致了错误。

为了正确获得 pip，用下面的方法修改 Dockerfile 应该可以解决问题：

RUN wget -q https://repo.continuum.io/miniconda/Miniconda3-4.2.12-Linux-x86_64.sh -O /tmp/miniconda.sh  && \
    echo 'd0c7c71cc5659e54ab51f2005a8d96f3 */tmp/miniconda.sh' | md5sum -c - && \
    bash /tmp/miniconda.sh -f -b -p /opt/conda && \
    /opt/conda/bin/conda install --yes -c conda-forge \
      python=3.5 sqlalchemy tornado jinja2 traitlets requests pip=18.0=py35_1001 pycurl \
      nodejs configurable-http-proxy && \
    /opt/conda/bin/pip install --upgrade pip && \
    rm /tmp/miniconda.sh
