The custom # config map data format defined incorrectly for opencost

[bd-spl]

The custom # data format defined for #_CONFIGMAP_NAME is incorrectly provided in the configmap template. As debugging of the source code shows, it only reads that data properly if defined directly, like this:

data:
  spotLabel: foo
  spotLabelValue: bar

See aws example for more possible data overrides.

Note that the case for what I was testing these data formats, is merging config overrides from a config map defined in #_CONFIGMAP_NAME. That only worked for the direct data format given above, even without extra volumes mounts that the helm chart normally creates, when .Values.opencost.custom#.enabled=true. Perhaps I am confusing that config option to my special case?

Also note that the volume mount created for the custom # config should not be readOnly, as opencost errors out like this:

INF ERROR UPDATING custom-#-model CONFIG: error writing config file for provider config: Failed to write file: open /tmp/custom-config/aws.json: read-only file system

update: the mounted volume should be fine, I confused it with the exporter chart, but that is another story
