Cluster autoscaler<\/strong><\/h3>\r\n\r\n\r\n\r\n

GKE<\/a>‘s cluster autoscaler automatically resizes the number of nodes in a given node pool, based on the demands of your workloads. You don’t need to manually add or remove nodes or over-provision your node pools. Instead, you specify a minimum and maximum size for the node pool, and the rest is automatic.<\/p>\r\n\r\n\r\n\r\n

In the Cluster, Click on Pencil icon of Autoscaling profile.<\/p>\r\n\r\n\r\n\r\n
