Upgrade Kubernetes Version

Change the version field on an existing kupe_cluster and apply. The platform performs a rolling upgrade of the control plane in place — workloads remain available.

resource "kupe_cluster" "production" {
  name         = "production"
  display_name = "Production"
  type         = "shared"
  version      = "1.32"   # upgraded from 1.31
  # ...
}

terraform plan
terraform apply

The upgrade is asynchronous — terraform apply returns once the API has accepted the change, not when the cluster has finished upgrading. Monitor cluster phase via the console or data.kupe_cluster to know when the upgrade is complete.

For the underlying lifecycle and rollback considerations, see Upgrade Clusters.
