If you are using your template nodes in the `kwok-provider-templates` ConfigMap, make sure you have set the correct value for `nodegroups.fromNodeLabelKey`/`nodegroups.fromNodeAnnotation`. Not doing so will make CA not scale up nodes (it won't throw any error either).

Set `readNodesFrom` in `kwok-provider-config` ConfigMap to `cluster`. This tells the kwok provider to use live nodes from the cluster as template nodes.

### Gotchas

1. The kwok provider by default taints the template nodes with `kwok-provider: true` taint so that production workloads don't get scheduled on these nodes accidentally. You have to tolerate the taint to schedule your workload on the nodes created by the kwok provider. You can turn this off by setting `nodes.skipTaint: true` in the kwok provider config.

2. Make sure the label/annotation for `fromNodeLabelKey`/`fromNodeAnnotation` in the kwok provider config is actually present on the template nodes. If it isn't present on the template nodes, the kwok provider will not be able to create new nodes.
