# 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 . --values values-prod.yaml` ## Output - Complete Helm chart directory structure - `Chart.yaml` with metadata and dependencies - `values.yaml` with documented, configurable defaults - Template files: `deployment.yaml`, `service.yaml`, `ingress.yaml`, `configmap.yaml`, `serviceaccount.yaml`, `hpa.yaml` - `_helpers.tpl` with name, label, and selector helper templates - `NOTES.txt` with post-install access instructions - Environment-specific values override files ## Error Handling | Error | Cause | Solution | |-------|-------|---------| | `Chart.yaml: version is required` | Missing or malformed `version` field | Add a valid SemVer version string to Chart.yaml | | `parse error in template` | Go template syntax error (missing `end`, wrong function) | Run `helm template .` to pinpoint the error; check bracket matching and function names | | `dependency not found` | Chart dependency not downloaded | Run `helm dependency update` to fetch dependencies into `charts/` | | `release failed: timed out waiting for condition` | Pods not reaching ready state during install | Check pod logs; verify image exists, resource limits are sufficient, and probes are correct | | `values override not applied` | Wrong values file path or key mismatch | Verify `--values` file path and that keys match the structure in `values.yaml` exactly | ## Examples - "Generate a Helm chart for a Node.js API with 3 replicas, an Nginx ingress, PostgreSQL subchart dependency, and environment-specific values for dev and prod." - "Create a Helm chart for a stateful application with PersistentVolumeClaim, headless service, and configurable storage class." - "Package an existing set of Kubernetes manifests into a Helm chart with parameterized image tag, replica count, and resource limits." ## Resources - Helm documentation: https://helm.sh/docs/ - Chart best practices: https://helm.sh/docs/chart_best_practices/ - Template function reference: https://helm.sh/docs/chart_template_guide/function_list/ - Artifact Hub (chart discovery): https://artifacthub.io/
Related Skills
generating-unit-tests
This skill enables Claude to automatically generate comprehensive unit tests from source code. It is triggered when the user requests unit tests, test cases, or test suites for specific files or code snippets. The skill supports multiple testing frameworks including Jest, pytest, JUnit, and others, intelligently detecting the appropriate framework or using one specified by the user. Use this skill when the user asks to "generate tests", "create unit tests", or uses the shortcut "gut" followed by a file path.
generating-test-reports
This skill generates comprehensive test reports with coverage metrics, trends, and stakeholder-friendly formats (HTML, PDF, JSON). It aggregates test results from various frameworks, calculates key metrics (coverage, pass rate, duration), and performs trend analysis. Use this skill when the user requests a test report, coverage analysis, failure analysis, or historical comparisons of test runs. Trigger terms include "test report", "coverage report", "testing trends", "failure analysis", and "historical test data".
generating-test-doubles
This skill uses the test-doubles-generator plugin to automatically create mocks, stubs, spies, and fakes for unit testing. It analyzes dependencies in the code and generates appropriate test doubles based on the chosen testing framework, such as Jest, Sinon, or others. Use this skill when you need to generate test doubles, mocks, stubs, spies, or fakes to isolate units of code during testing. Trigger this skill by requesting test double generation or using the `/gen-doubles` or `/gd` command.
generating-test-data
This skill enables Claude to generate realistic test data for software development. It uses the test-data-generator plugin to create users, products, orders, and custom schemas for comprehensive testing. Use this skill when you need to populate databases, simulate user behavior, or create fixtures for automated tests. Trigger phrases include "generate test data", "create fake users", "populate database", "generate product data", "create test orders", or "generate data based on schema". This skill is especially useful for populating testing environments or creating sample data for demonstrations.
generating-stored-procedures

Use this skill when the user asks to "generate stored procedure", "create database function", "write a trigger", or needs help with "database logic", "optimizing database performance", or "ensuring transaction safety" in their database. The skill is activated by requests related to database stored procedures, functions, or triggers.
generating-orm-code
This skill enables Claude to generate ORM models and database schemas. It is triggered when the user requests the creation of ORM models, database schemas, or wishes to generate code for interacting with databases. The skill supports various ORMs including TypeORM, Prisma, Sequelize, SQLAlchemy, Django ORM, Entity Framework, and Hibernate. Use this skill when the user mentions terms like "ORM model", "database schema", "generate entities", "create migrations", or specifies a particular ORM framework like "TypeORM entities" or "SQLAlchemy models". It facilitates both database-to-code and code-to-database schema generation.
generating-infrastructure-as-code
This skill enables Claude to generate Infrastructure as Code (IaC) configurations. It uses the infrastructure-as-code-generator plugin to create production-ready IaC for Terraform, CloudFormation, Pulumi, ARM Templates, and CDK. Use this skill when the user requests IaC configurations for cloud infrastructure, specifying the platform (e.g., Terraform, CloudFormation) and cloud provider (e.g., AWS, Azure, GCP), or when the user needs help automating infrastructure deployment. Trigger terms include: "generate IaC", "create Terraform", "CloudFormation template", "Pulumi program", "infrastructure code".
