  • After entering all information for a cluster to be created, the user wants to enable the autoscale feature by clicking Autoscale in the Worker Configuration section.

  • Select the Scale min parameter (the number of remaining nodes when scale down) and scale max (the maximum number of nodes that can be scaled up).

  • After enabling autoscale for 1 k8s cluster, click create cluster.

Ø Node:

  • When entering the quantity for scale max/min, you have to check if there is enough quota, if the input exceeds the allowed quota, it will display an insufficient quota message as below:

  • To fix it, reduce the max/min scale to the allowed quota.

  • After entering the parameters, click the Autoscale button to enable this feature.

  • After clicking Autoscale, the status of the cluster is Enable scaling.
