When will LKE Autoscaling Scale DOWN node pools?
Trying out the new LKE Autoscaling feature and I saw it successfully scale UP the node pools when pods couldn't be scheduled. But now that the pods have finished I have a LKE node doing nothing (save the default kubernetes pods) and it hasn't scaled down yet. Does this happen automatically via a timer or does Autoscaling only scale up?
When you configure cluster autoscaling, you set a minimum and maximum number. These numbers need to be between 1-99. This means that, if there is one node left, this would meet the allowed minimum requirements.
Please note that setting the minimum or maximum outside of the current number of nodes will not cause the autoscaler to adjust the current number. This is to prevent any unintended disruption in existing workloads.
