Helm: Charts, Repositories, and Release Management

Helm is the Kubernetes package manager — the tool you reach for when kubectl apply -f becomes unwieldy. Five manifests today becomes fifty tomorrow, and suddenly you're managing configuration drift across environments, tracking which version deployed where, and praying your rollback works when production breaks.

Helm solves this by packaging Kubernetes resources into charts — versioned, parameterized bundles that install as a single release. Think of it as apt or Homebrew for Kubernetes: you install charts from repositories, customize values, and track each deployment as a numbered revision.
