Helm is package manager for Kubernetes. Helm helps you manage Kubernetes applications. Helm Charts helps you define, install, and upgrade even the most complex Kubernetes application. Charts are easy to create, version, share, and publish.

Helm is made of two components: the CLI binary named helm that allows you to perform communication with a remote component, named tiller that lives inside your Kubernetes cluster that is responsible to perform patches and changes to resources you ask to manage. 

Helm can be installed by below way:

Download installables
sudo curl -LO https://git.io/get_helm.sh

provide permission
sudo chmod 700 get_helm.sh

Execute script to install 
sudo ./get_helm.sh

 
Verify installation

helm version --client

 

Tiller

Tiller is the service that actually communicates with the Kubernetes API to manage our Helm packages.

 

cat <<EOF > tiller-rbac-config.yaml

apiVersion: v1
