Helm is a package manager for kubernetes. Helm is kubernetes version of yum or apt. Helm deploys charts, Charts are packages of pre-configured Kubernetes resources.In this blog we will see how to deploy helm version 2 in Kubernetes cluster.

Requirements :

Helm Version 2 installation:

Step 1:

Install helm,

# cd /tmp
# curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get > helm.sh

Helm version 2 is based on tiller.

First create service account for tiller in Kubernetes and bind to cluster admin,

# kubectl -n kube-system create serviceaccount tiller

# kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller

Step 3:

It can be verify by checking tiller pod is running fine,

# kubectl get pods -n kube-system|grep tiller

Check helm version,

Step 5:

Install an application via helm,

Add a repo for the particular application in helm.
