What is Helm?

A package manager for Kubernetes that simplifies deploying and managing applications using reusable, configurable charts.

Helm packages Kubernetes resources into charts — reusable bundles of YAML templates with configurable values. Instead of managing dozens of Kubernetes manifests, you install a chart with helm install and customize via values.yaml.

Helm supports versioned releases, upgrades, rollbacks, and dependency management. Chart repositories share community and enterprise charts. Popular charts exist for databases, monitoring stacks, and web applications.
