How can I install MSSQL Server in a Python Docker image?

I want to install MSSQL Server in a Python docker container to be able to run unit tests in a CI pipeline.

The problem is that the installation keeps failing. How can I fix it?

What I've tried

FROM python:3.7.9-slim-buster
RUN apt-get update

RUN apt-get -y install gnupg curl software-properties-common wget
RUN add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/ubuntu/18.04/mssql-server-2019.list)"
RUN curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add - \
    && apt-get update \
    && ACCEPT_EULA=Y DEBIAN_FRONTEND=noninteractive apt-get install -y \
    unixodbc-dev \
    mssql-server
ENV MSSQL_PID 'developer'
ENV MSSQL_SA_PASSWORD 'Devel0per'
RUN /opt/mssql/bin/mssql-conf -n setup accept-eula
ENV SQLALCHEMY_DATABASE_URI mssql+pyodbc://dev_user:Devel0per@localhost:5432/dev_db

This gives:

Step 8/9 : RUN /opt/mssql/bin/mssql-conf -n setup accept-eula

    raise child_exception

Try 2

FROM mcr.microsoft.com/mssql/server:2019-latest
RUN apt-get update

gives

The second example should be:

FROM mcr.microsoft.com/mssql/server:2019-latest
USER root
RUN apt-get update && \
    # install python

USER mssql

Microsoft doesn't document it anywhere, but this image contains two users and sets the unpriviledged user mssql as the default one.
