Feature Request: Generate values.schema.json from values.yaml or Helm templates

[faiteanu]

The plugin description reads: "The plugin provides several actions to generate JSON schemas for values of Helm charts."

Looking at the code (e.g. generateValuesJsonSchema), the method name suggests that a schema is generated from values. However, I could not find any place in the code where values.yaml is actually read from the file system, which makes the description misleading.

Feature Request

I would like to have an option to generate a values.schema.json from either:

• a values.yaml file, or
• the templates in the Helm chart (e.g. by analysing .Values.* references)

Example

Given the following values.yaml:

postgresDb:
  enabled: true
  instances:
    - name: mydb
      dbName: sampledatabase

and a template like this in templates/_postgresdb.yaml:

{{- if .Values.postgresDb.enabled }}
{{- range $_, $db := .Values.postgresDb.instances }}

Both representations allow deducing that postgresDb is an object with an enabled property and an instances array, which could be translated into a JSON schema automatically.
It would also be useful to support comments in values.yaml or the template that get rendered as description fields in the resulting schema.

Question

Is there a public sample repository showing the intended use of this plugin?
