python, mariadb library and his connector inside a docker container

Question

I'm trying to create a container for my python project that uses mariaDB. Here there are dockerfile's lines related to the problem:

FROM python:3.10.6-slim-buster

ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update  && \
    apt-get install -yq apt-utils && \
    apt-get install -yq procps && \
    apt-get install -yq nano && \
    apt-get install -yq libmariadb3 libmariadb-dev
RUN rm -rf /var/lib/apt/lists/*

RUN pip install --no-cache-dir -r requirements.txt

In my requirements.txt I have:

mariadb==1.1.4

When I run the docker build it returns me this error:

Collecting mariadb==1.1.4

As you can see, I installed the required packages for the connector via apt-get, the installation works without error, but I am still having this problem.

Do you have any idea?

Thank you.

This seems to happen because the python connector wants a specific version of the c connector, but due to a coding error is unable to tell you which. [This answer](https://stackoverflow.com/a/73074751/5320906) may help. — snakecharmerb, Aug 14 '22 at 11:55

Sorry, my bad - When formatting the code in 1.1.4 with Flake8 (PEP-8) the brackets around the tuple accidentally disappeared, this is already fixed in 1.1.5 (not released yet)

Minimum required Connector/C version is 3.2.4. Buster has MariaDB Server 10.3, corresponding C/C version is 3.1.x - so instead of buster you should bookworm (Server version 10.6.8, C/C version 3.2.8).

nothing changed... I used ```FROM python:3.10.6-bullseye``` in my dockerfile and running the build it gives me the same exact error. It doesn't work. – Codename47 Aug 14 '22 at 16:12
What is output of mariadb-config --cc_version in bullseye? – Georg Richter Aug 14 '22 at 16:20
```mariadb-config --cc_version --> 3.1.16``` Is there any workaround? – Codename47 Aug 14 '22 at 16:26
I've updated my answer, you need bookworm instead of bullseye – Georg Richter Aug 14 '22 at 16:52
