This is my docker file :

  • My computer os : Window 10

Do I need to setup something in docker container in order to allow it to connect with sql-server?

I have fixed this.
The solution : I need to install ODBC Driver 17 for SQL Server – for Debian 10 in my docker container
Thanks to alwayslearning for giving me the hint in comment section

This is my latest Dockerfile

FROM python:3.8-slim-buster

RUN apt-get update
RUN apt-get update && apt-get install -y gnupg2
RUN apt-get install -y curl apt-transport-https
RUN curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
RUN curl https://packages.microsoft.com/config/debian/11/prod.list > /etc/apt/sources.list.d/mssql-release.list
RUN apt-get update
RUN ACCEPT_EULA=Y apt-get install -y msodbcsql17 unixodbc-dev

WORKDIR /prefect-docker
