How to set up Helm for Kubernetes Cluster
Helm is the package manager for kubernetes, in this tutorial we will set up Helm on GKE cluster for
installing charts with Helm. Below are the steps for installing and set up Helm on GKE.
Login to Google Cloud Console
Activate Cloud Shell 
to open Cloud Shell.
Create Cluster on GKE (Google Kubernetes Engine)
gcloud container clusters create test-cluster --num-nodes 2 --enable-ip-alias --zone us-central1-a
Download Latest Helm Binary from github
Wget https://get.Helm.sh/Helm-v2.16.8-linux-amd64.tar.gz
Unpack downloaded Helm archive
tar zxfv Helm-v2.16.8-linux-amd64.tar.gz
Copy Helm binary to home directory
cp -rp linux-amd64/Helm ~
Get current user account details and save into environment variable
export user_account=$(gcloud config get-value account)
Check value of user_account
echo $user_account
Create clusterrolebinding with cluster-admin role for your user account that is saved in $user_account
kubectl create clusterrolebinding admin-binding --clusterrole=cluster-admin --user=$user_account
For deploying charts with Helm ,
server side of Helm that is tiller is required,
create tiller service account with name tiller in kube-system namespace
kubectl create serviceaccount tiller --namespace kube-system
For deploying charts kubernetes service account tiller requires cluster-admin role in the cluster,
create clusterrolebinding for tiller account with below command
kubectl create clusterrolebinding tiller-binding --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
Now initialize Helm with service account tiller
~/helm init --service-account=tiller
Check Helm version
~/helm version
Install nginx with Helm
~/helm install --name release-1 stable/nginx-ingress
If you get below error, than upgrade tiller
Error: incompatible versions client[v2.16.8] server[v2.14.1]
Upgrade Tiller with ~/helm init -–upgrade
~/helm init -–upgrade
Try again installing nginx with Helm
~/helm install --name release-1 stable/nginx-ingress
Check running pods
Kubectl get pods
