Omnis App Server running in Windows Docker Container

[Alan Davey]

Hey Everyone,

Just wanted to circle back on this as I finally got it working.  It turns
out that the servercore image with IIS that I was using didn't include a
full set of APIs and Services which led to the omnis.exe crashing when the
service tried to initialize it.

Using the full windows image for 2019 resolved the issue.
FROM mcr.microsoft.com/windows:ltsc2019

I then needed to add a command to my Dockerfile to install IIS:
RUN dism.exe /online /enable-feature /all /featurename:iis-webserver
/NoRestart

After building the image and launching a container I'm then able to access
both IIS and the Omnis Service from my localhost.

Hopefully this is helpful to others that may be looking to create a similar
environment using containers.

Alan
