Andrew Pruski demonstrates WinDocks, for people without Windows Server 2016 available:
So the first thing to do is get a new server with Windows Server 2012 R2 installed. Then once that’s up and running, you need to install SQL Server…
…wait, what??
The WinDocks software is different from the previous docker software that we’ve worked with in that it needs an instance of SQL installed on the host in order to use it’s binaries to create SQL within the containers. The instance won’t need to be running, it just needs to be installed.
Check out WinDocks; it’s focused around Dockerizing older versions of SQL Server.
