Mattermost on Azure (not AKS)

Hello. I have been trying to figure out for some weeks now if it is possible to run Mattermost on Azure without having to use AKS. I know you can run it as containers, which is fine. But what I don’t want to do is to run the databases as containers. I would very much like to use a managed database. I have basically tried every service available on Azure; SQL, Postgres MySQL etc. It seems like those services cannot be used by Mattermost for some limitations on the specific services in question. All information seems to be targeted to AWS services which is not an option for us at the moment.

Has anyone actually produced a production-ready Mattermost installation in AKS without having to use containers for the databases?
