SKE: Can not deploy latest K8s Version (preview)

[slm0n87]

Hi,

the latest K8s Version in SKE is 1.29 in state preview.

Trying to use it with the TF provider I got the error:

Plan: 1 to add, 0 to change, 0 to destroy.
stackit_ske_cluster.dnse2e: Creating...
╷
│ Error: Error creating/updating cluster

TF code (some fields x-out):

resource "stackit_ske_cluster" "xxxxx" {
  name                   = "test"
  project_id             = "xxxxxxxxxxxxxxx"
  kubernetes_version_min = "1.29"
  node_pools = [
    {
      name               = "pool1"
      machine_type       = "c1.2"
      minimum            = "1"
      maximum            = "3"
      availability_zones = ["eu01-1"]
    }
  ]
}

terraform {
  required_providers {
    stackit = {
      source  = "stackitcloud/stackit"
      version = "0.22.0"
    }
  }
}

The function getLatestSupportedKubernetesVersion only takes care about versions in "state supported".

But as a TF user I also want to use/test the new preview versions of Kubernetes.
(The same probably applies to "state deprecated" version - at least as long as they are able to be provisioned"state deprecated" can not be deployed anymore)

IMHO the logic needs to be adapted for kubernetes_version_min to something like:

• search for a version in state "supported"
• if no result - search for a version in state "preview"
• if no result - search for a version in state "deprecated"

This would result into having the "bestSupported" kubernetes_version.

Hi @slm0n87,

That is a good suggestion, thanks! We will plan it and soon will work on extending the current logic.

I updated my last comment after clarification that state "deprecated" can not be deployed anymore.
