Answer 1

I ran into this problem when creating a Dockerfile for Django with a python-alpine image.

I was able to solve it thanks to this post adding the package "graphviz-dev" along with the rest of my app's dependencies.

Example:

#Install dependencies
RUN apk add --update --no-cache --virtual .build-deps \
    build-base \
    alpine-sdk \
    postgresql-dev \
    libffi-dev \
    python3-dev \
    libffi-dev \
    jpeg-dev \
    zlib-dev \
    musl-dev \
    libpq \
    graphviz-dev \  
    && pip install --no-cache-dir -r /code/requirements_dev.txt \
    && find /usr/local \
        \( -type d -a -name test -o -name tests \) \
        -o \( -type f -a -name '*.pyc' -o -name '*.pyo' \) \
        -exec rm -rf '{}' +
