Helm

The package manager for Kubernetes that templates, installs, upgrades, and rolls back applications packaged as charts.

Definition

Helm 3 is client-only (Tiller was removed) and stores release state as Secrets in the target namespace. Charts are distributed via repositories or OCI registries.

Example

helm upgrade --install web bitnami/nginx -n web -f values-prod.yaml

Exam tip

Helm 3 has no Tiller; release history lives in Kubernetes Secrets.
