Re: Does Qlik support ABDI deployed on-premises using RedHat OpenShift or Mesosphere DC/OS?????
I believe QABDI is still supported using RedHat OpenShift or Mesosphere DC/OS. This would not be any different than if you did a bare metal Kubernetes installation. However with that said, Qlik will only support the QABDI functionality. If you configure Kubernetes incorrectly, that will be out of scope for support. Out of the above, I would suggest Mesosphere because they are K8s certified. I did not see that certification on RedHat's page, though I didn't look intensively.
I imagine Qlik cannot release documentation for other products. You will need to follow the appropriate documentation provided by the vendor of your choice as well as K8s documentation on Kubernetes itself.
