The most recent PHP-FPM container now provide
sqlsrv PHP modules for accessing Microsoft SQL databases.
Unfortunately the modules alone will not be sufficient for MSSQL connections. Additionally users must install the MS ODBC driver. As those driver require you to explicitly accept their EULA/license during installation they cannot be provided by default.
To ease the installation the Devilbox now provides an autostart script for automated installs of the MS ODBC driver during startup. This will usually only take 1-2 seconds.
The only thing you will need to do, is to accept the license once by altering the script. See documentation below.
