Dockerfile can't open ODBC driver 17 and fails during running the python script - docker

Question

I have create in docker 2 contains 1 to run the MSSQL server and the other a python container with the code to read data from an .xlsx file and inserting it into SQL server.
My Dockerfile has the below code :
FROM python:3.6-alpine
RUN apk update
RUN apk add gcc libc-dev g++ libffi-dev libxml2 unixodbc-dev mariadb-dev postgresql-dev
FROM continuumio/miniconda3
ADD test.py /
RUN apt-get update -y \
&& apt install python3 -y \
&& apt install python3-pip -y \
&& apt install python3-venv -y \
&& python3 -m venv venv
RUN apt-get -y install curl
**#Install FreeTDS and dependencies for PyODBC**
RUN apt-get update && apt-get install -y tdsodbc unixodbc-dev \
&& apt install unixodbc-bin -y \
&& apt-get clean -y
RUN apt-get update
RUN apt-get install -y tdsodbc unixodbc-dev
RUN apt install unixodbc-bin -y
RUN apt-get clean -y
RUN pip install pandas
RUN pip install pyodbc
RUN pip install DateTime
RUN pip install multiprocess
RUN pip install threaded
CMD [ "python", "./test.py" ]
It compiles successfully but fails every time i run the container with the below error :
pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'ODBC Driver 17 for SQL Server' : file not found (0) (SQLDriverConnect)")
I have been trying this for days but found no resolution.
Believe I need to install ODBC driver 17, if so how do I add it to my Dockerfile?
