Don't we need to clean up if it is deleting? I am thinking that there could be a situation where the user paused the cluster, then deleted (forgetting to unpause first), then unpause.


// List all OpenStackServers in the cluster
serverList := &infrav1alpha1.OpenStackServerList{}
if err := r.Client.List(
ctx,
serverList,
client.InNamespace(c.Namespace),
client.MatchingLabels{clusterv1.ClusterNameLabel: c.Name},
); err != nil {
log.Error(err, "Failed to list OpenStackServers for cluster")
return nil
}

// Create reconcile requests for all servers
requests := make([]ctrl.Request, 0, len(serverList.Items))
for i := range serverList.Items {
server := &serverList.Items[i]
requests = append(requests, ctrl.Request{
NamespacedName: client.ObjectKey{
Namespace: server.Namespace,
Name: server.Name,
},
})
log.V(5).Info("Queueing OpenStackServer for reconciliation", "server", server.Name)
}

return requests
}
