docker - Docker 构建失败并出现“找不到秘密 pip：未找到”错误

问题描述

我正在尝试构建一个 docker 映像但得到

secret pip not found: not found

对此有什么想法吗？

Dockerfile：

FROM <jfrog dockerfile package>
SHELL ["/bin/bash", "-c"]

RUN apt-get update \
 && apt-get -y install chromium chromium-driver
COPY requirments.txt 
RUN pip install -r requirments.txt
USER nobody
CMD robot ./smoketests-nonprod.robot \ 
 && robot ./smoketests-prod.robot

日志如下：

$ docker build -t robottests .

任何帮助，将不胜感激

解决方案

这是使用相对较新的 --secret 选项，它允许您在构建时挂载机密

您使用它的一般方式是您在外面有一个秘密文件并为其分配一个 id

在您的情况下，您将在pip.conf某处有一个文件并在您的构建命令中指定它：

docker build --secret id=pip,src=pip.conf -t robottests .

这将使pip.conf构建期间可用，但不是图像的一部分（可能是因为它包含用于访问内部 pypi 的身份验证机密）
