### NOTE: The following workaround is not longer working and therefore no longer needed, 
### but is left here for reference
########################################################################################

### NOTE: there appears to be an undocumented edge-case preventing Debian9 from
# succesfully installing mkdocs with python3. Here, we're explicitly copying the
# dependencies from a pinned squidfunk/mkdocs-material image, which should
# always 'just work'
#RUN python3 -m pip install --no-cache-dir importlib_metadata
#COPY --from=squidfunk/mkdocs-material:5.5.12 /usr/local/lib/python3.8/site-packages/ /usr/local/lib/python3.5/dist-packages/

# This makes the 'mkdocs' command work as a 'docker run' argument
COPY bin/docker-mkdocs /usr/local/bin/mkdocs
RUN chmod +x /usr/local/bin/mkdocs
