Dockerfile

FROM python:3.11-slim-bookworm

# Notes by Just van den Broecke
# July 2020
# The original image (from 2019), based on Debian Buster Python3 was around 1GB.
# Slimmed down to 294MB by:
# - using Debian Slim image.
# - Using https://github.com/geopython/pygeoapi/blob/master/Dockerfile as example.
# - avoided building wheels by installing python- packages
# - removing build dependency packages.
#
# Upgrade notes: Debian bullseye-slim (follow up from Buster) has Python 3.8
# Currently compat problem with MP 1.12.0 because of "cgi" packages
# See issue: https://github.com/mapproxy/mapproxy/issues/462
# like wsgi-plugin-python3 (needs to wait)
#
# Upgrade notes: in bullseye: use libproj19 uwsgi-plugin-python3 (i.s.o. pip3 uwsgi)
# --plugin /usr/lib/uwsgi/plugins/python3_plugin.so in uwsgi command and remove --wsgi-disable-file-wrapper

# May 2024
# * Python 3.11 and MapProxy 2.0.2
# * upgrade Base image to python:3.11-slim-bookworm
# * drop support for EPSG:900913
# * patch TMS demo HTML
