Summary of Changes

Hello @Jeffwan, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a robust JSON schema (values.schema.json) for the Helm chart's values.yaml files, enabling comprehensive input validation. Alongside this, it updates the existing stable.yaml, values.yaml, and vke.yaml files to ensure their data types and structures conform to the newly defined schema, thereby improving the reliability and maintainability of the Helm chart configuration.

Highlights

• Helm Chart Validation: A new values.schema.json file has been added to provide a comprehensive JSON schema for validating Helm chart input values, covering image specifications, resource requirements, probe configurations, Redis connection parameters, and all component configurations.
• Configuration Alignment: Existing values.yaml files (stable.yaml, values.yaml, vke.yaml) have been updated to align their data types (e.g., CPU values from integer to string, Redis tag from number to string) and key names (pullPolicy to imagePullPolicy) with the new schema's requirements.
• Enhanced Reliability: The introduction of the schema and the subsequent data type fixes ensure that Helm linting passes with schema validation enabled, leading to more robust and error-resistant chart deployments.

Code Review

This pull request introduces a values.schema.json to improve Helm chart robustness. The schema is well-structured, and the updates to the values.yaml files are correct. I recommend enhancing the schema to improve its correctness and consistency, specifically around environment variable validation, container image definitions, and probe configurations.
