Zone Label
The datacenter property was removed from the Server object (see changelog. For backwards compatibility, we statically compute the datacenter from the location to fill the topology.kubernetes.io/zone and failure-domain.beta.kubernetes.io/zone labels. In the next major release we will stop setting these values. To stop setting these values now, you can set the environment variable HCLOUD_INSTANCES_ZONE_LABEL_ENABLED=false. See here for more details.
