I currently have the following Dockerfile
to create my Docker image.
FROM python:3.6.6-alpine3.8
# Add dependencies for Python packages pandas, numpy and pyodbc
RUN apk add --no-cache curl gcc g++ unixodbc-dev
RUN ln -s /usr/include/locale.h /usr/include/xlocale.h
# Project files
ARG PROJECT_DIR=/srv/scripts
RUN mkdir -p $PROJECT_DIR
WORKDIR $PROJECT_DIR
COPY requirements.txt ./
# Install Python dependencies
RUN pip install --upgrade pip
RUN pip install -r requirements.txt
I would like to include various ODBC drivers in this image so that I can use them to connect to different databases from the Python program running in my container.
Pyodbc
to connect to databases. I wanted to start with PostgreSQL thinking it would be the easiest one but I could not find any package on the Alpine Linux Package manager . Do you have any idea how I should install such a driver?
I was facing the same issue. I solved this issue by adding RUN apk update
before RUN apk add
commands.(I was using python:3.6-alpine)
Dockerfile
FROM python:3.6-alpine
RUN apk update
RUN apk add gcc libc-dev g++ libffi-dev libxml2 unixodbc-dev mariadb-dev postgresql-dev
As the OP ended moving away from Alpine- to a Debian-base image, and another answer has a small snapshot of a working Dockerfile, I will flesh out a full Dockerfile that builds SQL Server ODBC Driver 17 into a Debian-base image.
# load python 3.8 dependencies using slim debian 10 image.
FROM python:3.8-slim-buster
# build variables.
ENV DEBIAN_FRONTEND noninteractive
# install Microsoft SQL Server requirements.
ENV ACCEPT_EULA=Y
RUN apt-get update -y && apt-get update \
&& apt-get install -y --no-install-recommends curl gcc g++ gnupg unixodbc-dev
# Add SQL Server ODBC Driver 17 for Ubuntu 18.04
RUN curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add - \
&& curl https://packages.microsoft.com/config/debian/10/prod.list > /etc/apt/sources.list.d/mssql-release.list \
&& apt-get update \
&& apt-get install -y --no-install-recommends --allow-unauthenticated msodbcsql17 mssql-tools \
&& echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile \
&& echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
# upgrade pip and install requirements.
COPY /requirements.txt /requirements.txt
RUN pip install --upgrade pip
RUN pip install -r /requirements.txt
# clean the install.
RUN apt-get -y clean
# copy all files to /app directory and move into directory.
COPY . /app
WORKDIR /app
ENTRYPOINT ["some", "python", "command"]
如果您担心保持轻量级,特别是在 odbc 的情况下,我建议使用 debian:stretch 图像。
