Generating Helm Charts

Overview

Generate production-ready Helm 3 charts for Kubernetes applications with Chart.yaml, values.yaml, Go templates, and helper functions. Support multi-environment deployments with values overrides, dependency management, security contexts, health probes, and resource limits following Helm best practices.

Prerequisites

• Helm 3.x installed (helm version)
• kubectl configured with cluster access for testing chart installation
• Container images available in a registry accessible from the cluster
• Understanding of application resource requirements (CPU, memory, ports, volumes)
• Chart repository access if publishing (ChartMuseum, OCI registry, or GitHub Pages)

Instructions

1. Analyze the application: identify container images, ports, environment variables, volumes, and dependencies
2. Scaffold the chart structure: Chart.yaml, values.yaml, templates/, charts/, .helmignore
3. Create Chart.yaml with apiVersion: v2, name, version, appVersion, and dependency declarations
4. Define values.yaml with sensible production defaults: replica count, image config, resource limits, ingress settings
