Mikael,
Unfortunately ISAM 9.0.7.1 does not officially support OpenShift 4.4.x. We are however looking at adding this support in the next release, which is due out at the end of the year.
I would be interested in knowing more about the security constraints issue which you encountered. The official documentation does explain that you need to set up a special security constraint in order to be able to run ISAM under OpenShift - did you follow these instructions?
Also, there are currently no plans to introduce an operator for ISAM. We will however soon be releasing an operator for the IBM Application Gateway image (which is the new light-weight/container-native WebSEAL image).
I hope that this helps.
