Override fake node name

[mispon]

Hello!

To test my task, I need to create nodes with a special name.

I have tried overriding the name with

kwokctl scale node --param '.name="new-node-name"'

and with KwokctlResource like this:

apiVersion: config.kwok.x-k8s.io/v1alpha1
kind: KwokctlResource
metadata:
  name: node
parameters:
  podCIDR: "10.0.0.1/24"
template: |
  kind: Node
  apiVersion: v1
  metadata:
    name: "new-node-name"

but nodes are still created with the default name node-000000.

Is it possible to override the name at the moment?

The KwokctlResource needs to be specified with --config or you can add it to ~/.kwok/kwok.yaml, when the cluster is created.

@wzshiming hi! yes, it is in my kwok.yaml file
Through the resource, I override the annotations and labels (this works) and the node name (this doesn't work for me)

kwokctl scale node custom-name --replicas 1

Ohhh, I forgot, it can specify the resource name

Thank you! It is exactly what I looking for
