-			if !existsSubnet {
-				return false, fmt.Errorf("failed to get subnet")
+			if subnet.ID == nil {


when can this happen? when subnet is not nil but subnet.ID is nil?

I think first subnet is always not nil. Then, before subnet is az.getSubnet() for the first time, its ID is nil.

pips may not be in az.ResourceGroup. That can be specified from annotation.

Good catch! Updated
