func ScaleDownOrderedByDescendingCost ¶
func ScaleDownOrderedByDescendingCost(ctx context.Context, vca scalesim.VirtualClusterAccess, w http.ResponseWriter, nodes []corev1.Node) ([]string, error)
ScaleDownOrderedByDescendingCost scales down the nodes in the cluster ordered by descending cost. It does the following
- Order all existing nodes by their cost.
- Iterate over all existing ordered nodes, for each node: 1.1 Taint the node with NoSchedule. 1.2 Get the pods on the node and deploy a copy of the pods with new names in the cluster. 1.3 Check whether there are un-scheduled pods. If len(unscheduledPods) == 0 { then delete the node from virtual cluster and record as recommendation else { mark as essential (not to be removed). Delete the newly deployed pods. Un-taint the node if this node is essential. }
