Question

我在名为docker_test的目录中有一个Dockerfile。 docker_test的结构如下：

M00618927A:docker_test i854319$ ls 
Dockerfile  hello_world.py

我的dockerfile如下所示：

  ### Dockerfile 

# Created by Baktaawar 

# Pulling from base Python image 

FROM python:3.6.7-alpine3.6

# author of file
LABEL maintainer="Baktawar"

# Set the working directory of the docker image 
WORKDIR /docker_test
COPY . /docker_test


# packages that we need

RUN pip --no-cache-dir install numpy pandas jupyter


EXPOSE 8888

ENTRYPOINT ["python"]

CMD ["hello_world.py"]

我运行命令

docker build -t dockerfile .

它开始构建过程，但是由于无法获取图像中安装的numpy等而出现以下错误

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-8c3o0ycd/pandas/
You are using pip version 18.1, however version 19.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
The command '/bin/sh -c pip --no-cache-dir install numpy pandas jupyter' returned a non-zero code: 1

如何完成此基本设置？

您基本上需要在alpine上安装以下软件，才能安装numpy：

apk --no-cache add musl-dev linux-headers g++

尝试以下Dockerfile：

### Dockerfile
# Created by Baktawar
# Pulling from base Python image

FROM python:3.6.7-alpine3.6

# author of file
LABEL maintainer="Baktawar"

# Set the working directory of the docker image
WORKDIR /app
COPY . /app

# Install native libraries, required for numpy
RUN apk --no-cache add musl-dev linux-headers g++

# Upgrade pip
RUN pip install --upgrade pip

# packages that we need
RUN pip install numpy && \
    pip install pandas && \
    pip install jupyter

EXPOSE 8888

ENTRYPOINT ["python"]

CMD ["hello_world.py"]

我认为这个高山包也很有趣：

更新

为了正确标记图像，请使用以下语法：

docker build -f <dockerfile> -t <tagname:tagversion> <buildcontext>

对您来说，这将是：

docker build -t mypythonimage:0.1 .

Docker为numpy构建，熊猫给出错误
