What this skill does
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 5. Build templates using Go template syntax with proper .Values references and helpers.tpl for reusable named templates 6. Add health checks: livenessProbe and readinessProbe in the deployment template with configurable paths and thresholds 7. Configure security context: runAsNonRoot: true, readOnlyRootFilesystem: true, and drop all capabilities 8. Create environment-specific values files: values-dev.yaml, values-staging.yaml, values-prod.yaml 9. Add NOTES.txt with post-install instructions showing how to access the application 10. Validate with helm lint . and test rendering with helm template . …
