lgtm, could you add a note about the testing done @mbolt35 ? it's sufficient to just paste the output of helm template with the values changed and make sure it runs and the output is sane.

Updated values.yaml nodeSelector in networkCosts node like so:

  nodeSelector: 
    ssd: "true"

Ran:

helm template --name=kubecost --namespace=kubecost ./cost-analyzer -f ./cost-analyzer/values.yaml -f ./cost-analyzer/values-thanos.yaml --set networkCosts.enabled=true > k.yaml

Observed the output for network-costs in k.yaml
