Query Helm Chart Resources Using JSON

Deploying a Helm chart to Kubernetes just to query resources is time consuming. It's possible to directly query a Helm chart using JSON with this simple trick.

After deploying a Helm chart into Kubernetes, it's easy to query the resources using kubectl with JSONPath expressions. That's not always an option, though. I recently needed to calculate the total CPU, memory, and storage allocated for a production sized deployment that wasn't deployed yet, but I didn't have a non-production environment large enough to deploy and then query. Wouldn't it be nice if you could query Helm charts using JSON?
