Hello Sharon,
Yes I was able to work through all of our issues. We are able to successfully build the containers in Azure DevOps on Premise. Our challenge was getting some of the Ubuntu Libraries and Gosu download due to security protections, but we modified the docker files to look locally for the files, and were able to build them successfully.
For HTTPS, the keystore needed to be a JKS format, where the traditional RHEL version supported PKCS 12. Also there was an issue where some of the special characters in the Docker Compose file were causing the line to truncate so the SSL keystore password in the server.xml file was not correct.
For SSO, there are not any Docker specific instructions. I followed the same instructions for standard deployment, and just placed the files in the Docker Mounted ThingWorx Platform folder.
We have successfully build the containers, and rebuild when a newer version has come out. They have been deployed to multiple instances.
