Microsoft SQL Server 2016 Express

The Microsoft SQL Server 2016 Express image requires Windows Server 2016 and provides one environment variable (sa_password) that is used to set the sa password. SQL Server is installed with default setup parameters that could be modified (if needed).

You can run the container with the following command:
docker run -d -p 1433:1433 --env sa_password=<YOUR SA PASSWORD> mssql-server-2016-express-windows
