Hello Gerlof,
We only test against AKS, EKS, GKE, OCP and Tanzu, and we only have those available to us to reproduce related problems when customers open a support case. Though we have just updated our techdocs to make a clear statement of reasonable commercial effort support for all other Kubernetes distributions, we have no plans to do that for non-Kubernetes container platforms.
That said, we have provided individual statements of reasonable commercial effort support for other platforms (e.g. AWS Fargate) to specific customers, but only after they have demonstrated a high level of expertise and self-sufficiency with that platform, and it's clear they understand and accept even more limited reasonable commercial effort support.
If, under those circumstances, you're still interested in non-Kubernetes container platforms in Azure, please reach out to me directly.
