 Absolute number is calculated from percentage by rounding down. This can not be 0 if Max_surge is 0. By default, a fixed value of 1 is used. Example: when this is set to 30%, the old Rc can be scaled down to 70% of desired pods immediately when the rolling update starts. Once new pods are ready, old Rc can be scaled down further, followed by scaling up the new Rc, ensuring that the total number of pods available at all times during the update is at least 70% of desired pods.</p></dd></dl><div class="spec m
