Kubernetes Helm

Helm is a tool for managing Kubernetes charts. Charts are packages of pre-configured Kubernetes resources.

Use Helm to...

• Find and use popular software packaged as Kubernetes charts
• Share your own applications as Kubernetes charts
• Create reproducible builds of your Kubernetes applications
• Intelligently manage your Kubernetes manifest files
• Manage releases of Helm packages

Helm in a Handbasket

Helm is a tool that streamlines installing and managing Kubernetes applications. Think of it like apt/yum/homebrew for Kubernetes.

• Helm has two parts: a client (helm) and a server (tiller)
• Tiller runs inside of your Kubernetes cluster, and manages releases (installations) of your charts.
• Helm runs on your laptop, CI/CD, or wherever you want it to run.
• Charts are Helm packages that contain at least two things:
  • A description of the package (Chart.yaml)
  • One or more templates, which contain Kubernetes manifest files
• Charts can be stored on disk, or fetched from remote chart repositories (like Debian or RedHat packages)

Install

Binary downloads of the Helm client can be found at the following links:

• OSX
• Linux
• Linux 32-bit
• Windows

Unpack the helm binary and add it to your PATH and you are good to go! OS X/Cask users can brew cask install helm.

To rapidly get Helm up and running, start with the Quick Start Guide.

See the installation guide for more options, including installing pre-releases.
