Node Pool Labels does nothing

[regnaio]

Vultr API - Create NodePools

labels (object): Map of key/value pairs defining labels to automatically apply to all nodes in this nodepool. Labels will be applied to both new and existing nodes.

I added multiple key/value pairs for labels using govultr, but these labels are not applied to the nodes according to kubectl get no --show-labels

I'm confused what is the point of specifying labels if they are not applied to nodes. Also, these labels don't appear in the Vultr Web UI

Basically, the labels field does nothing

This is likely an issue in the API but I'll review the logic in govultr to be sure.

With this update code:

    newLabels := map[string]string{
        "label-test":   "test-label",
        "label-test-2": "test-label-2",
    }

    np, _, err := client.Kubernetes.UpdateNodePool(ctx, vkeID, nodePoolID, &govultr.NodePoolReqUpdate{
        Labels: newLabels,
    })

I get labels in kubernetes.

kubectl get nodes --show-labels
beta.kubernetes.io/arch=amd64,beta.kubernetes.io/instance-type=vc2-2c-4gb,beta.kubernetes.io/os=linux,failure-domain.beta.kubernetes.io/region=ewr,kubernetes.io/arch=amd64,kubernetes.io/hostname=test-ne-np-09a9d79e220d,kubernetes.io/os=linux,label-test-2=test-label-2,label-test=test-label,node.kubernetes.io/instance-type=vc2-2c-4gb,region=EWR,topology.kubernetes.io/region=ewr,vke.vultr.com/gpu=false,vke.vultr.com/node-id=ed2d1c57-28d0-4f9e-8831-44f15d4d8ceb,vke.vultr.com/node-pool-id=b3662053-11c2-475b-832b-e36d9aaaecf2,vke.vultr.com/node-pool=test-ne-np,vke.vultr.com/version=v1.29.2-1

...

Will you share what code you're using with govultr to apply the labels?

Thanks, @optik-aper. I only tried creating a Cluster with Node Pools Labels defined.

nps := []govultr.NodePoolReq{
    ...
    Labels: map[string]string{
        "key": "val",
    },
}

c, _, err := v.client.Kubernetes.CreateCluster(context.Background(), &govultr.ClusterReq{
    Label:     "<NAME>",
    Region:    "<REGION>",
    Version:   "<VERSION>",
    NodePools: nps,
})

I haven't tried updating a Node Pool. I thought creating the Cluster with Node Pool Labels defined would be enough

[optik-aper]

Ah, yes. It appears that the create node pool doesn't process labels. But that's not govultr's doing; the create params don't include them in the API.

We'll have to address that there. But you ought to be able to create and then update at this point.

[regnaio]

Ah, thank you for the heads up, @optik-aper. It's great to know that this can be achieved with Update

[optik-aper]

I'll keep this open until we decide how to fix the create labels but I think it will be added soon.
