我正在尝试学习如何将python应用程序转换为docker容器。
我的文件夹中有以下文件：
我的Dockerfile如下：
FROM alpine:latest
RUN apk add --no-cache python3-dev && pip3 install --upgrade pip
WORKDIR /app
COPY . /app
RUN pip3 --no-cache-dir install -r requirements.txt
在我的要求中。txt
numpy==1.13.0
pandas==0.25.0
当我使用以下图像构建图像时：
docker build -t mscons_trial .
前4个步骤运行正常，但第5步引发以下错误：
Step 5/5 : RUN pip3 --no-cache-dir install -r requirements.txt

我对docker完全陌生，所以我不知道我是否在做错误。
任何帮助将不胜感激。谢谢
答案 0 :(得分：1)
在安装您的要求之前，将其添加到您的dockerfile中：
RUN apk update && apk add --no-cache --virtual build-dependencies libc-dev build-base
答案 1 :(得分：0)
尝试在第一个命令中运行apk add alpine-sdk
答案 2 :(得分：0)
进行调试，我建议尝试：
docker run -it alpine:latest /bin/sh
哪个将显示sh提示符，然后运行：
# echo "numpy==1.13.0" > requirements.txt
# echo "pandas==0.25.0" >> requirements.txt
# apk add --no-cache python3-dev && pip3 install --upgrade pip
# pip3 --no-cache-dir install -r requirements.txt
