Helm

Helm is the package manager for Kubernetes, providing a way to define, install, and upgrade complex Kubernetes applications through reusable templates called charts. Helm charts encapsulate all the Kubernetes resources needed for an application, making deployments reproducible and shareable. A Helm chart packages Kubernetes manifests with configurable values, enabling teams to customize deployments for different environments (development, staging, production) without modifying the underlying templates. Artifact Hub hosts thousands of community-maintained charts for popular applications. Helm 3, the current major version, removed the server-side component (Tiller) and uses Kubernetes secrets for release management, significantly improving security and simplifying the architecture.
