Install pandas in a Dockerfile

Question

I am trying to create a Docker image. The Dockerfile is the following:

# Use the official Python 3.6.5 image
FROM python:3.6.5-alpine3.7

# Set the working directory to /app
WORKDIR /app

# Get the 
COPY requirements.txt /app
RUN pip3 install --no-cache-dir -r requirements.txt

# Configuring access to Jupyter
RUN mkdir /notebooks
RUN jupyter notebook --no-browser --ip 0.0.0.0 --port 8888 /notebooks

The requirements.txt file is:

jupyter
numpy==1.14.3
pandas==0.23.0rc2
scipy==1.0.1
scikit-learn==0.19.1
pillow==5.1.1
matplotlib==2.2.2
seaborn==0.8.1

Running the command docker build -t standard . gives me an error when docker it trying to install pandas. The error is the following:

Collecting pandas==0.23.0rc2 (from -r requirements.txt (line 3))

When I try to install a lower version of pandas==0.22.0, I get this error:

  Could not find a version that satisfies the requirement Cython (from versions: )
No matching distribution found for Cython
The command '/bin/sh -c pip3 install --no-cache-dir -r requirements.txt' returned a non-zero code: 1

I also tried to install Cyphon and setuptools before pandas, but it gave the same No matching distribution found for Cython error at the pip3 install pandas line.

How could I get pandas installed.

Answer 1

Alpine don't contain build tools by default. Install build tool and create symbolic link for locale:

$ apk add --update curl gcc g++
$ ln -s /usr/include/locale.h /usr/include/xlocale.h
$ pip install numpy
