Version charts for reproducibility
Document charts clearly in README.md
Separate values per environment
Frequently Asked Questions about Helm
What is Helm?
Helm is an open-source package manager for Kubernetes that allows developers and operators to define, install, and manage Kubernetes applications using reusable Helm charts.
What are the primary use cases for Helm?
Deploying Kubernetes applications via Helm charts. Managing complex application dependencies. Application version control and rollback. Parameterizing deployments for multiple environments. Automating CI/CD deployment workflows
What are the strengths of Helm?
Simplifies Kubernetes application deployment. Versioned releases and easy rollback. Reusability via charts. Strong community support and ecosystem. Integrates with CI/CD pipelines
What are the limitations of Helm?
Helm templating can be complex for beginners. Debugging templated manifests may be tricky. Does not manage runtime cluster state directly. Helm hooks may introduce non-deterministic behavior. Limited support for non-Kubernetes environments
