What Helm is

Helm is a free package manager for applications running in Kubernetes clusters. It groups related Kubernetes resources into versioned charts that can be shared, installed, upgraded, or rolled back. Charts can declare dependencies, and operators can supply different values to the same chart for development, staging, and production. Helm manages applications such as databases, monitoring stacks, and ingress controllers. Its command-line client communicates with the Kubernetes API server, while the Helm library handles chart operations. Release information is stored in Kubernetes Secrets, so Helm does not need a separate database. Charts can be kept on disk or fetched from remote repositories; Artifact Hub lists publicly available charts. Plugins extend Helm, including with custom chart-download protocols. It runs on Linux, macOS, and Windows as a self-managed command-line tool under the Apache-2.0 license. Helm focuses on applications inside a Kubernetes cluster; setting up and operating the cluster itself is outside its scope.

Who it suits

Helm suits application operators, distributors, developers, and supporting tool developers working with Kubernetes applications. It is not for setting up or operating the Kubernetes cluster itself.

What it does well

Packages related Kubernetes resources into versioned charts
Supports upgrades and rollbacks
Charts can use different values across environments
Stores release information in Kubernetes Secrets

What to know first

Focuses on applications running in Kubernetes
Cluster setup and operation are outside its scope

Getting started

Open the Helm website.
Choose a supported installation method for Linux, macOS, or Windows.
Install using a pre-built binary or the installer script, or use a listed community package manager.
Use the command-line client to work with charts and the Kubernetes API server.

Verdict

Helm organizes Kubernetes application resources into reusable charts, with support for dependencies, environment-specific values, upgrades, and rollbacks. It is free and self-managed, but does not cover operating the cluster itself.

Questions
