Building Thingworx Docker Image on Raspberry Pi

Has anyone tried building a Thingworx Docker image using Ubuntu on a Raspberry Pi?  I'm getting very close, but failing when the "build.sh" file (provided from PTC) tries to build the MS SQL image. Getting the below error:

Would this be a lot easier if I used something like Postgres instead of MSSQL?  Anyone had any luck doing this on a Raspberry Pi, or do I need an x86 version of Ubuntu to do this?

Appreciate any help.
