helm-chart-generator_skill

Overview

This skill generates complete Helm chart files for deploying applications to Kubernetes. It produces a valid Helm 3.x chart layout including Chart.yaml, values.yaml, and template files. The output is ready to package or install with helm commands.

How this skill works

When triggered, the skill inspects the provided application details (image, ports, replicas, ingress, environment variables) and emits a consistent Helm chart structure. It creates parameterized templates for Deployment, Service, ConfigMap/Secret (if needed), and Ingress, plus a values.yaml that captures deploy-time options. The generated files follow best practices for Helm 3 and are organized under a chart directory.

When to use it

• You need a quick, ready-to-use Helm chart for a new or existing containerized app.
• Converting ad-hoc kubernetes manifests into a reusable, parameterized Helm chart.
• Bootstrapping charts for CI/CD pipelines or developer onboarding.
• Creating charts for different environments by editing values.yaml.

Best practices

• Provide concrete application details: image name and tag, ports, and desired replicas.
• Keep environment-specific overrides in values.yaml or environment-specific values files.
• Use template helpers and label conventions to ensure consistency across resources.
• Limit hard-coded values in templates; expose common settings through values.yaml.
• Validate generated charts with helm lint and test installs in a non-production namespace.

Example use cases

• Create Helm chart for web application with a Deployment, Service, and Ingress ready for staging.
• Generate a chart for a microservice with configurable environment variables and resource requests/limits.
• Convert Docker Compose or raw Kubernetes manifests into a parameterized Helm chart.
• Produce charts for automated CI/CD pipelines that package and publish Helm archives.
• Quickly scaffold charts for internal tooling or proof-of-concept deployments.
