Scale Cluster Resources

Raise cpu, memory, or storage on an existing kupe_cluster resource and Terraform updates the limits in place; nothing else in the block needs to change.

resource "kupe_cluster" "production" {
  name    = "production"
  version = "1.31"

  resources = {
    cpu     = "8"       # scaled from 4
    memory  = "32Gi"    # scaled from 16Gi
    storage = "200Gi"   # scaled from 100Gi
  }
}

terraform plan   # shows the resource changes
terraform apply  # applies them

resources is mutable, so this is an in-place update; Terraform does not replace the cluster. For the underlying API call, see Scale and Upgrade Clusters via the API.
