cluster autoscaling

https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/container_cluster#

• google_container_cluster

Example

 cluster_autoscaling {
   enabled = true
   autoscaling_profile = "OPTIMIZE_UTILIZATION"
   resource_limits {
     resource_type = "cpu"
     minimum = 1
     maximum = 4
   }
   resource_limits {
     resource_type = "memory"
     minimum = 4
     maximum = 16
   }
Ref: https://stackoverflow.com/a/63684343

autoscaling_profile: [ BALANCED | OPTIMIZE_UTILIZATION ]

Incomplete example, resource_limits are mandatory:

  cluster_autoscaling {
    enabled = true
  }
