bug: etcd restore failing on getting rke2_node_name

[michalg91]

Summary

When i try to restore newly deployed cluster from s3 backup task that gathers all rke2_node_name from inventories is failing. In debug mode i can see that vars are gathered also from localhost which is not using this variable since it is not in rke2_cluster_group_name which in my case is k8s_cluster. I am setting all rke2 setting in group_vars/k8s_cluster/rke2.yaml so group_vars/all/main.yaml files has no rke2 settings at all.

The related task is here: to

ansible-role-rke2/tasks/first_server.yml

Lines 169 to 173 in 602b420
