Cluster API metadata propagation

[galiev]

Could you help me please. Should cluster-api metadata propagation work with cluster-api-bootstrap-provider-talos, or should I define node labels in the config?

versions used:

result:

unfortunately the label node-role.kubernetes.io/worker=nodepool-md0 is not added

Yes, at the moment it needs to be defined as a config patch for a machine config. CABPT doesn't have any integration with CAPI metadata, but it might be a nice feature.
