Docker PHP-FPM Alpine with SQLSRV Driver Error

I am getting this error when I try to connect to the sqlserver db:

Array ( [0] => Array ( [0] => IMSSP [SQLSTATE] => IMSSP [1] => -49 [code] => -49 [2] => This extension 
requires the Microsoft ODBC Driver for SQL Server. Access the following URL to download the ODBC 
Driver for SQL Server for x64: https://go.microsoft.com/fwlink/?LinkId=163712 [message] => This 
extension requires the Microsoft ODBC Driver for SQL Server. Access the following URL to download the 
ODBC Driver for SQL Server for x64: https://go.microsoft.com/fwlink/?LinkId=163712 ) )

My Dockerfile below:

CMD ["php-fpm", "-F"]

WORKDIR /var/www/cssp

EXPOSE 9000

It seems there is a problem with the installation of the driver
Has anyone tried this before? Please share. Thank you.
