Unable to render chart with `values-vsphere.yaml`

[lindhe]

The chart fails to render when using values-vsphere.yaml:

$ helm template charts --values charts/values-vsphere.yaml
Error: template: cluster-template/templates/nodeconfig-vsphere.yaml:22:34: executing "cluster-template/templates/nodeconfig-vsphere.yaml" at <2>: invalid value; expected string

Use --debug flag to render out invalid YAML

I think it's because cloudConfig in values-vsphere.yaml is null and this line expects a string:

cluster-template-examples/charts/templates/nodeconfig-vsphere.yaml

Line 22 in dc5c201

{{ $nodepool.cloudConfig | indent 2 }}
