What is Helm?

Last Updated May 3rd 2022, 12:41:16 am

Description

Helm is a tool that streamlines installing and managing Kubernetes applications. It is a package manager for Kubernetes.

How to install Helm[1] [2]

Manual Install

  1. Download your desired version: https://github.com/helm/helm/releases

  2. Unpack it (tar -zxvf helm-v3.0.0-linux-amd64.tar.gz)

  3. Find the helm binary in the unpacked directory, and move it to its desired destination (mv linux-amd64/helm /usr/local/bin/helm)

Scripted Install

Helm now has an installer script that will automatically grab the latest version of Helm and install it locally.[3]

You can fetch that script, and then execute it locally. It’s well documented so that you can read through it and understand what it is doing before you run it.[3:1]
