There are many ways by which we can install helm 3 on to our machines

From the Binary Releases

Every release of Helm provides binary releases for a variety of OSes. These binary versions can be manually downloaded and installed.

• Download your desired version
• Unpack it (tar -zxvf helm-v3.0.0-linux-amd64.tar.gz)
• Find the helm binary in the unpacked directory, and move it to its desired destination (mv linux-amd64/helm /usr/local/bin/helm)

From Script

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

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.

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3

chmod 700 get_helm.sh

./get_helm.sh

Through Package Managers

The Helm community provides the ability to install Helm through operating system package managers. These are not supported by the Helm project and are not considered trusted 3rd parties.

From Homebrew (macOS)

Members of the Helm community have contributed a Helm formula build to Homebrew. This formula is generally up to date.

brew install helm

(Note: There is also a formula for emacs-helm, which is a different project.)

From Chocolatey (Windows)

Members of the Helm community have contributed a Helm package build to Chocolatey. This package is generally up to date.

choco install kubernetes-helm

From Apt (Debian/Ubuntu)

Members of the Helm community have contributed a Helm package for Apt. This package is generally up to date.
