Step-by-Step Guide to Installing Helm 3 and Helm 2 on Linux

This guide shows how to install Helm 3 on a Linux host.

# Download Helm 3 binary
wget https://get.helm.sh/helm-v3.7.0-rc.2-linux-amd64.tar.gz
# Extract the archive
tar -zxvf helm-v3.7.0-rc.2-linux-amd64.tar.gz
# Move the executable to a directory in PATH
sudo mv linux-amd64/helm /usr/local/bin/helm

Next, the article explains installing Helm 2 client and the Tiller server component.

# Download Helm 2 binary
wget https://get.helm.sh/helm-v2.17.0-linux-amd64.tar.gz
# Extract the archive
tar xvf helm-v2.16.9-linux-amd64.tar.gz
cd linux-amd64
# Copy the binary to a directory in PATH
cp -a helm /usr/local/bin/

To run Tiller, a ServiceAccount and ClusterRoleBinding must be created. The required manifest (helm-rbac.yaml) is shown below.

apiVersion: v1
kind: ServiceAccount
metadata:
  name: tiller
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: tiller
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: tiller
  namespace: kube-system

Apply the RBAC configuration: kubectl apply -f helm-rbac.yaml Initialize Tiller with the created ServiceAccount and a specific image, and point Helm to a stable repository mirror:

helm init --service-account tiller \
  --tiller-image=registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.17.0 \
  --stable-repo-url http://mirror.azure.cn/kubernetes/charts

Verify that Tiller is running:

kubectl get deployment tiller-deploy -n kube-system

Finally, check the client and server versions: helm version Reference: https://www.cnblogs.com/keithtt/p/13171160.html
