Docker image ghcr.io/mapproxy/mapproxy/mapproxy:2.0.2-dev doesn't contain necessary pip packages

[Dronis2000]

Image ghcr.io/mapproxy/mapproxy/mapproxy:2.0.2-dev gets error on startup:
Found libproj >=5. Using this library without pyproj is deprecated and not fully supported. Please install pyproj >= 2. Traceback (most recent call last): File "/usr/local/bin/mapproxy-util", line 5, in <module> from mapproxy.script.util import main File "/usr/local/lib/python3.10/site-packages/mapproxy/script/util.py", line 29, in <module> from mapproxy.script.conf.app import config_command File "/usr/local/lib/python3.10/site-packages/mapproxy/script/conf/app.py", line 32, in <module> from .sources import sources File "/usr/local/lib/python3.10/site-packages/mapproxy/script/conf/sources.py", line 17, in <module> from mapproxy.srs import SRS File "/usr/local/lib/python3.10/site-packages/mapproxy/srs.py", line 26, in <module> from mapproxy.proj import USE_PROJ4_API File "/usr/local/lib/python3.10/site-packages/mapproxy/proj.py", line 282, in <module> res = try_import() File "/usr/local/lib/python3.10/site-packages/mapproxy/proj.py", line 155, in try_libproj_import libproj = init_libproj() File "/usr/local/lib/python3.10/site-packages/mapproxy/proj.py", line 66, in init_libproj libproj.pj_init_plus.argtypes = [c_char_p] File "/usr/local/lib/python3.10/ctypes/__init__.py", line 387, in __getattr__ func = self.__getitem__(name) File "/usr/local/lib/python3.10/ctypes/__init__.py", line 392, in __getitem__ func = self._FuncPtr((name_or_ordinal, self)) AttributeError: /lib/x86_64-linux-gnu/libproj.so.25: undefined symbol: pj_init_plus

Context

I tried to run the dev docker image (ghcr.io/mapproxy/mapproxy/mapproxy:2.0.2-dev) in Kubernetes. The container started, but didn't display home page on port 8080. Logs contain error (see above).

Expected Behavior

I can see MapProxy homepage on port 8080.

Actual Behavior

The port 8080 is unaccessible.

Possible Fix

To fix the problem I added pip packages pyproj and boto3 to docker image and saved new image to my local docker registry. My Dockerfile:
FROM ghcr.io/mapproxy/mapproxy/mapproxy:2.0.2-dev
RUN pip3 install pyproj boto3

I can reproduce the error and will work on a fix.

I created this PR for this: #909

is the boto3 dependency really needed to run mapproxy or is this something needed for additional functionality?

The boto3 is used for s3 caches which I would consider a core part in mapproxy (cannot differentiate between different cache types). There is an option to use http instead of boto, but I think boto is the default.

Sorry for the late response, but I was not sure before if my fix was applicable in the first place. What version of boto3 should be included? ==1.34 would be the current one. Or can we use >=1 or something to make builds with older python versions possible? @weskamm can you say something about this?

[weskamm]

builds passed for all supported python versions with 1.34 before, so no need to lower that
