尝试使用 Airflow 基础镜像在 docker 构建中 pip install pyportfolio opt 时，运行 `cc --version` 给出“[Errno 13]权限被拒绝：'cc'”

Question

我正在创建一个 apache 气流应用程序，它需要使用 python 包 pyportfolioopt 或 cvxpy。在 dockerfile 中，我当前使用 apache/airflow:2.8.4 作为基础映像。 当我使用下面的文件运行 docker-compose up --build 时，出现错误：

在下面的 DockerFile 中添加注释代码可以解决该问题，但结果是气流应用程序无法正常运行，并且出现错误：服务“airflow-init”未成功完成：退出 127

FROM apache/airflow:2.8.4

# Adding this commented code fixes the issue but i airflow app will return error 
#FROM python:3.9. 
#RUN apt-get update && apt-get install -y \
#    libopenblas-dev \
#    liblapack-dev \
#    libatlas-base-dev \

Answer 1

根据Docs，当你扩展Docker镜像并添加apt包时，你首先需要切换到USER root，添加包，然后切换回USERairflow。

FROM apache/airflow:2.8.4

USER root 
RUN apt-get update && apt-get install -y \
    libopenblas-dev \
    liblapack-dev \
    libatlas-base-dev \
    gfortran

COPY requirements.txt .
USER airflow
RUN pip install -r requirements.txt

您需要确保使用 Airflow 用户安装 Python 要求。
