Hi, In our testing of Caracal Magnum, we saw that the cluster upgrade feature is now disabled for clusters using the Heat driver. There are many good reasons for this explained at [1] and [2] in particular. But I don't see any Magnum documentation of this new approach to K8s cluster provisionning. Is https://vexxhost.github.io/magnum-cluster-api/ the authoritative place? I had a quick look to the URL above but I am not sure I understood what configures Magnum to use Cluster API rather than Heat driver. Is Magnum configured to use one or the other for all clusters it manages? Is it a per cluster choice? How it works to transition from Heat driver to Cluster API, ie how it works if you have existing clusters configured with Heat drivers and if you are creating new ones with Cluster API? Best regards, Michel [1] https://opendev.org/openstack/magnum/commit/2fd3059f3885ff4a14f7f01410161960...
