Installing helm on Kubernetes

Installing helm

In this module we are going to deploy Helm on Kubernetes.
There is a script below to install the Helm binary

#!/bin/bash

if [[ "$OSTYPE" == "linux-gnu" ]]; then
    OS="linux"
    ARCH="linux-amd64"
elif [[ "$OSTYPE" == "darwin"* ]]; then
    OS="osx"
    ARCH="darwin-amd64"
fi    
HELM_VERSION=2.11.0
curl -sL "https://storage.googleapis.com/kubernetes-helm/helm-v$HELM_VERSION-$ARCH.tar.gz" | tar xz
chmod +x $ARCH/helm 
sudo mv $ARCH/helm /usr/local/bin/

Now we will set up the service account and role binding to give Helm the permissions that it needs.

Installing Tiller

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: ServiceAccount
metadata:
  name: tiller
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: tiller
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: tiller
    namespace: kube-system
EOF

Lastly we will connect our Helm client to tiller

helm init --service-account tiller
